[beagleboard] Re: Build a QT/11 application for beagleboard black by cross compiling from ubuntu

[Mirko Fucci]

Yes i meant on the BBB copying the executable file.
That tutorial worked well for me, consider that to run tha executable
you need to exit form X-environemt and launch the program with -qws 
parameter.

Whati kind of problems did you have ?

Does your router have another port?  You need to connect your BBB to your 
router so that it can talk to the network.  At the moment it's only talking 
to your desktop via USB.

[beagleboard] Re: To CANBUS or not to CANBUS

[Rusty Wright]

Mind you, I haven't done anything like this, but if I did I'd use zigbee. 
 I read and enjoyed the book Building Wireless Sensor Networks (second 
edition) by Robert Faludi.  It's specifically about zigbee.  He uses the 
XBee radios, from Digi International; they look reasonably priced.  For the 
computer he uses an Arduino, but it'd probably be easy to translate the 
concepts to the BBB.

What I think most or maybe just me is not getting is why you're not just
making the package yourself? There is no "porting" to be done. It is
already setup to run for linux, and like the other post said you just
need to do it for armv7 vs armv6. You just need to compile for your
needs, very simple to do yourself.

Also what OS are you doing this on? If you were on Arch you could use
their PKGBUILD and just type this
makepkg
pacman -U pkgname
bam

I know on debian/ubuntu it pretty simple to make your own pkg as well
angstrom well I wont even comment.

If you really just want a package for the BB and just cant be bothered
to compile it yourself, then contact me off list

Re: [beagleboard] Re: Touchscreen Jitter / Jumping on Beaglebone Black LCD Capes

[Terry Storm]

Ditto.

Regarding the fix which makes this work 99% of the time...
Have you considered the noise could be on the power lines which power the 
touch screen?
One could assume the power rails are meant to be between GND and VCC, 
however this may not be the case. It then assumes GND is 0 and VCC is Max. 
Since there are 4 AIN's used, it should be possible to read the voltages... 
Maybe do some sort of ratio calculation or something.
Just a thought.

Mark,

 

This is not my first rodeo. I am not expecting something for nothing.

 

In the posts on the Sedona forum, I said ...

I am comfortable with some software, not proficient in enough areas.

If someone has a BBB and would do this ...

If someone wants me to buy them a BBB so they can do this ...

 ... it would save me that much time.

I know what I am good at and where my time is best spent.


If it is OK to say here, I am willing to pay someone to do this.

 

I am not looking for any more pointers to give me direction. I am looking
for someone to do the task.

 

Tony

Re: [beagleboard] Re: Clone Ubuntu EMMC on BBB

[Brian Piccioni]

Thanks to the help of Robert and William I have successfully cloned a 
Ubuntu BBB. For posterity (i.e. the next Noob who struggle with this, I 
have written up the procedure I used.

Thanks again for the help.
Brian

*Start up the source BBB, booting Ubuntu off eMMC.*

 

*In order for this to work, uEnv.txt and /etc/fstab must use UUIDs for the 
root file system. My fstab was automatically generated and used UUIDs, 
however, uEnv.txt did not which meant the copy process did not function 
properly.*

 

*So you have to make sure uEnv.txt uses UUIDs. So, to the Find out what 
your UUIDs are*

brian@arm:/boot/uboot$ sudo blkid

/dev/mmcblk0p1: LABEL="storage" UUID="5bdb27fd-1cb8-4a08-b2c2-51062e8b2fa7" 
TYPE="ext4"

/dev/mmcblk1p1: SEC_TYPE="msdos" LABEL="boot" UUID="AEA7-4FDD" TYPE="vfat"

/dev/mmcblk1p2: LABEL="rootfs" UUID="d933e4fe-59f6-4344-9935-8f86c04b7481" 
TYPE="ext4"

 

*Edit uEnv.txt to use UUID for rootfs*

sudo nano /boot/uboot/uEnv.txt

 

*Replace the line*

mmcroot=/dev/mmcblk1p2 ro

 

*With the UUID of the root (i.e :UUID=d933e4fe-59f6-4344-9935-8f86c04b7481) 
and add mmcrootfstype as appropriate*

mmcroot=UUID=d933e4fe-59f6-4344-9935-8f86c04b7481

mmcrootfstype=ext4 rootwait fixrtc

 

*Save the file, double check to make sure you've saved it, made the right 
changes, etc..*

 

 

*Now to make a copy image (you do this once). On the Source BBB Remove Powe*

Insert bootable microSD ( I used Angstrom, marked ‘O’)

Insert thumb drive

Push ‘Boot’ button (near microSD card) and insert power AT LEAST until all 
4 LEDs light

Log in (as root, no password)

 

df - to see where the Thumb drive is mounted (/media/Lexar)

cd /media/Lexar

fdisk –l to list drives (eMMC will probably be /dev/mmcblk1)

 

*Copy mcblk1 to a backup image*

dd if=/dev/mmcblk1 of=BeagleBoneBlack-eMMC-image-Jan82014.img bs=10M

*(This takes about 5 minutes and you should get a result like this:*

183+1 records in

183+1 records out

1920991232 bytes (1.9 GB) copied, 336.935 s, 5.7 MB/s

 

 

*On the second (destination) BBB Remove Power*

Insert bootable microSD ( I used Angstrom, marked ‘O’)

Insert thumb drive

Push ‘Boot’ button (near microSD card) and insert power AT LEAST until all 
4 LEDs light

 

df - to see where the Thumb drive is mounted (/media/Lexar)

cd to the thumb drive /media/Lexar

fdisk –l to list drives (eMMC will probably be /dev/mmcblk1)

 

*Copy backup image to mcblk1 *

dd if=BeagleBoneBlack-eMMC-image-Jan82014.img of=/dev/mmcblk1 bs=10M

 

And get this result 

183+1 records in

183+1 records out

1920991232 bytes (1.9 GB) copied, 303.132 s, 6.3 MB/s

 

*Remove the uSD and USB Stick, reboot, log in and, find out what your UUIDs 
are (they should be the same as the source BBB)*

brian@arm:/boot/uboot$ sudo blkid

/dev/mmcblk0p1: LABEL="storage" UUID="5bdb27fd-1cb8-4a08-b2c2-51062e8b2fa7" 
TYPE="ext4"

/dev/mmcblk1p1: SEC_TYPE="msdos" LABEL="boot" UUID="AEA7-4FDD" TYPE="vfat"

/dev/mmcblk1p2: LABEL="rootfs" UUID="d933e4fe-59f6-4344-9935-8f86c04b7481" 
TYPE="ext4"

hi, Robert

Thank you for your advice.
The problem has been solved with usb-serial cable.

I'll ask this kind on freenode next time.

 The above link is an article I wrote in the subject of network booting.
 uboot, MLO, and uEnv.txt are on an SD card, but the kernel, and device tree
 overlay  is pulled in via TFTP, finally rootfs over NFS.

 This works fine, and might be a little slow, but nothing like what
 you're explaining in your post. I am just using the standard package that
 comes with Debian wheezy stable, and I have never experienced these
 problems you're mentioning here.

By broken out, I mean like built into a cape or something specific to being

[beagleboard] Minecraft Cape

[Joey Carlini]

Okay, so I loaded up one of Rob's images for Debian on the Beaglebone 
Black, and was able to get the Minecraft Launcher running with the Open-JDK 
and was able to login, but no dice getting the game to launch. Would it be 
possible to get a client running with the Beaglebone using some Java 
trickery, and if all went well, could it be broken out into it's own little 
unit, similar to Gamebone?

Re: [beagleboard] Re: 4D Systems 4DCAPE-70T, no display

[Brian Yee]

Terry,

Yes, the user light is on solid.  The curious thing is that this behaviour
is the same for a couple of
other BeagleBoards and 4D LCD shields.  I don't think it is the hardware,
unless there is some
sort of design problem.  Have you gotten one to work?

Thanks,

Brian

 That might be the problem then.
 The 4DCAPE-70T is based on the LCD7 A3, and the LCD7 A3 support on
 Angstrom only came out in August 2013 I believe.
 So reflash using the latest image and it should work, albeit the touch
 related issues which are discussed elsewhere.
 You could try the latest test release: http://downloads.angs
 trom-distribution.org/demo/beaglebone/testing/BBB-eMMC-
 flasher-v2013.06-2014.01.03.img.xz

 Else flash Android which is linked in the Datasheet from 4D, which does
 work correctly.

Re: [beagleboard] BeagleBone ProfiBus Cape

[guerreski]

Thank you for your answer,

yes, I checked, it says that this cape should be available since last 
spring, but it is not!

I have seen from the TI site the follow link, where they propose to use the 
integrate ISO1176T:

http://www.ti.com/tool/TIDA-5

do you think I can use that circuit instead waiting for the profibus cape?

Thank you very much,

Ubuntu is fine.. Remember this is just the "image-builder" it uses
debootstrap in a chroot to create a new fresh/clean image..

The kernel on the other hand.. you can build anywhere, native, cross, etc..

Well technically it's only one file different in the first boot partition:

https://github.com/beagleboard/image-builder/blob/master/scripts_device/am335x_evm.sh#L54

So if it finds "flash-eMMC.txt" in the first partition it'll flash the
eMMC... It's easier to just push out two images with different
functions then explainnig.. "mount ; rm flash-eMMC.txt ; "

Sounds good, I only have one of the breadboard capes which I have enabled 
two USARTS on.  so 3.13 
sounds like where I should start playing.

So to build for my one BBBk,  I would be better off doing the build on 
another ARM based machine running Debian.  Probably my best option would be 
to use my Odroid U2?  It has a 16gb emmc on it and i can plug in a 
microsd...   I am currently running Ubuntu on it, but can install Debian.

So  if I am reading this correct, Each time will overwrite the eMMC... I

I was porting it from my v3.7.x branch which had set everything up for
the xm..  However a lot had changed so I was tweaking things right up
to the point i found out it wouldn't work for my environment..

so as long as you cp the stuff from the ignore directory and place it
in the right spots it should work..

i think part of the problem, i haven't exactly finished the "install"
part of the sgx build script... so other then building stuff, it
doesn't finish the install..

The demos run fine for me. The default SDK places the demos in /opt

You need to run the following first:

sudo /etc/init.d/rc.pvr start

Then I run the demo as follows:

cd /opt/gfxsdkdemos/ogles2
./OGLES2ChameleonMan

Re: [beagleboard] Re: 4D Systems 4DCAPE-70T, no display

Is the USER LED flashing for you, or on solid?
If its not flashing then I don't think the Cape has been identified by the 
BBB correctly.
If you cant get it working, then you might have a dud one. Claim RMA and 
get it replaced.

[beagleboard] Re: weather cape

[David Anders]

Eric,

Koen Kooi was the original designer of the weather cape. the weather 
cape has been discontinued and no software support is planned for future 
releases of the example linux distribution shipped with the beaglebone 
black. the weather cape was initially marked as hardware incompatible 
because it does use a gpio as a test point that is also used by the on 
board eMMC used with the black.


there is no support provided for the weather cape when used with the 
beaglebone black

It's for the AM335x EVM but it should be easy enough to adapt it to any
AM335x system.

 Which version of u-boot are you using? Could it not also be the ethernet
 drivers? I would try updating to the latest u-boot version and see if
 you're still having issues.

how can I find out who that is that designed the weather cape?  The

[beagleboard] Re: Code protect

[mark . s . schaefer]

You might want to look at some of the Freescale processors.  Last time I 
heard (~2010), they had multiple levels of protection built in to the 
product.  You can burn in (write-once) an encryption key and then encrypt 
the contents of the FLASH using that key.  You can also have it checksum 
the contents of the boot code to prevent malicious code execution.  All of 
this does slow down the boot and causes headaches in manufacturing, but if 
you want to protect the bits, it's one of the few ways to do it.  Here is a 
security whitepaper for 
Freescale: http://cache.freescale.com/files/32bit/doc/white_paper/IMXSCRTYWP.pdf

Re: [beagleboard] Re: recommend usb external drive for booting?

[William Hermans]

Sounds like fun. The idea of being able to run a swap partition in this
instance sure does seems nice. In fact the drive I used to test the
material for the article I wrote: I forgot to add a swap partition. So I
created a swap file with dd . .  .it seems to work just fine.

For what it is worth. For my own ideal development environment I prefer to
netboot. Simply because I have the added horsepower of my "desktop" system,
and the ease of moving things around without having to interact with the
BBB directly. Generally this means that single non system files I can copy
over on the fly and test, while system directories or files can be done on
the fly, but *will* require a reboot. Plus the added benefit of using "non
destructive" media.

Have fun with your exploration :)

 So, what is a BIOS ? If in this case you are correct, then no computer
 system out there can boot off of USB. As all computer devices need to know
 how to bring up the hardware, DDR memory(
 now days ) , and from where to boot.

 Ok, so I was wrong, guess you do not care if someone can boot their
 BBB's off of a USB drive.

 You are correct those instructions should be modifed to note the
 reliance on
 the sd card or eMMC.

 I recall that the lack of booting straight from USB was designed in
 but I don't recall what the reason was. Do you know? It's common
 for devices to boot from USB and I even recall reading USB was
 checked
 during the boot process, after SPI (I think). I may have  read that
 in the
 TRM or is it SRM...?

Re: [beagleboard] Re: To CANBUS or not to CANBUS

[mark . s . schaefer]

Hi,

 I've done a bit of work with CAN, mainly in automotive and Freescale. 
 CAN is used heavily in automotive because it is deterministic, as you say. 
 That is, you can come up with a priority scheme that guarantees that 
higher priority messages get sent out without collisions.  You can read 
about the scheme on Wikipedia.

 I'm not sure about the CAN controller on the BBB, but one of the 
problems with CAN implementations is large numbers of interrupts on busy 
networks.  CAN is essentially a pub/sub network, where the receiver (at 
COMPILE time) registers for the set of messages it wants to receive.  Those 
messages are then compiled into a set of filters that get loaded into the 
CAN controller so that the number of hardware interrupts are reduced.  I'm 
not sure if the interrupt issue is still a problem, but there is still a 
lot of FUD around the industry about that.

 The Linux SocketCAN driver (developed at VW) is, I think, a vastly 
superior approach that uses some of the existing Linux network stack, but 
it doesn't use the hardware filtering capabilities of the hardware.

 For home use, I would look at Insteon (wired/wireless), Z-Wave 
(wireless) or Zigbee (wireless).  SmartHome is a good place to look at 
what's out there.  If you're going to create your own sensors, RS-485, 
suggested above, is probably an easier implementation than CAN.  Perhaps 
more information on your problem would help towards picking the right 
technologies.

The demos run fine for me. The default SDK places the demos in /opt

You need to run the following first:

sudo /etc/init.d/rc.pvr start

Then I run the demo as follows:

cd /opt/gfxsdkdemos/ogles2
./OGLES2ChameleonMan

Just start with wheezy:

http://elinux.org/BeagleBoardDebian#Debian_7_.28wheezy.29

install v3.13-rcX
wget http://rcn-ee.net/deb/wheezy-armhf/v3.13.0-rc7-bone3/install-me.sh
sudo /bin/bash install-me.sh

sudo reboot

then read up on:

[beagleboard] Re: Looking for someone to port software for me for BBB

[mark . s . schaefer]

It'll take getting your hands dirty or making it worth someone else's time 
and effort to get their hands dirty.  People in forums tend to be helpful 
when it comes to small requests, but it sounds like you're asking for 
someone to donate a weeks' worth of effort to just hand you something on a 
silver platter.  Just sayin'.

If you want to win kudos, you can do the work and then post the steps for 
others to benefit from your labor.

Re: [beagleboard] Re: recommend usb external drive for booting?

[Rusty Wright]

Yes, the writes to flash memory is my concern; wearing out the flash 
memory.  But I'm thinking that "doing a lot of development naively" isn't 
as much a problem as when you're running Linux.  Unix is a disk based 
operating system and it historically has written to the disk willy nilly. 
 Syslog is writing regularly, inodes are being updated when files are 
accessed, etc. My idea is exploring the BBB as a low power unix server.

Oh it's device tree based... The 'old style' is gone forever...  It's
just not 100% dynamic and endlessly configurable like 3.8 was...

Hi,

 I'm in the same boat.  I went through all of the listed suppliers, and 
now I'm bidding on a sole BBB on eBay.  Not in a huge hurry, since this is 
for a pet home project.  It really seems that the BBB has hit a sweet spot 
in terms of capability and price.  I have an HP server running my network 
that costs me $25-$30 a month in electricity, and I believe a BBB + a 
Synology NAS could to the same job for a fraction of the power consumption. 
 Just a DNS cache, NTP server, RADIUS/NIS/AD auth and SAMBA/NFS shares. 
 Maybe Asterisk.

Re: [beagleboard] TFTP from u-boot: slow and buggy

[lee]

Thanks, and I'd seen that article, but you're right--I'm doing something 
different. I have a BBB-based development board, and I'm writing a script 
that loads a full distribution onto it starting from a blank slate--i.e., 
nothing in the eMMC, no SD card. Most of it is working.

I think Jack is right--it's a network driver issue. When I revert to the 
stock u-boot v2013.10, the tftp works better.

Re: [beagleboard] Re: Which build would you recommend?

[William Hermans]

Robert, OK so maybe I am a bit slow on the uptake on this conversation, but
does the fact that you're trying to write in most / all capes indicate that
device tree will not happen in 3.12/3.13 ?

If this is right, does this mean the "old style" will be re implemented ?

Re: [beagleboard] Re: recommend usb external drive for booting?

[William Hermans]

The point was, if I had not answered the OP he would have been left with
the district feeling that what he wanted to do was not possible. When in
fact it was.

 If you want to be a 100% nitpicking techno-junkie, then a purely 100%
 SD/eMMC-less boot  can be had by using eprom . . . as it stands, this form
 of USB boot satisfies me, and 99% of the other people out there :)

If you want 'full' cape support stick with 3.8.. If you are just using
usb/ethernet with simple capes* (usart/i2c/spi) use 3.13 (i'm working
on adding most capes to 3.13 at the moment..)  ignore 3.12.. ;)

The scripts assume linux, mostly tested on debian jessie, but works in ubuntu..

Note the "image-builder" works best native on arm hardware.. (qemu is
too bit rotten for 100% reliably between distro versions)

There will be a traditional "flasher" which will overwrite the eMMC
and a secondary "4gb img" which you can dump to your microSD and it'll
run on that.

Re: [beagleboard] Re: Which build would you recommend?

[KurtE]

Yes, it is working good for me.  :)

But after reading the happy new year message, I have also been wondering 
that if the standard release will be Debian, should I try building my own 
images from the links that were listed there for both the actual image and 
kernel?  

But if I do, should I stick with the 3.8 kernel?  Or 3.12 or 3.13?  

My assumption is the build scripts assume I am running linux.  Can dual 
boot to this on my main dev machine to Linux Mint, or could use my NUC 
which I think right now I have running Ubuntu 13.04.

A few more things to investigate:
1) If I build an image and write it to an SD card, can I try it out (boot 
off of it) without it overwriting the EMMC?

2) I am trying to learn ROS and convert my code of at least one of my 
robots to use it.  I tried building it on my BBBk, but don't think 2gb is 
enough storage to build even the minimal install from sources.  Some 
options to look at:
a) Is there some place to apt-get install from? I saw a posting for 
downloading on Angstrom and maybe Ubuntu... More to look at.
b) Run off of SD card with more storage? 
...

3) Boot off of EMMC, but have more storage external.  SD or USB thumb???

Re: [beagleboard] TFTP from u-boot: slow and buggy

[William Hermans]

http://www.embeddedhobbyist.com/debian-tips/beaglebone-black/beaglebone-black-network-boot/

The above link is an article I wrote in the subject of network booting.
uboot, MLO, and uEnv.txt are on an SD card, but the kernel, and device tree
overlay  is pulled in via TFTP, finally rootfs over NFS.

This works fine, and might be a little slow, but nothing like what you're
explaining in your post. I am just using the standard package that comes
with Debian wheezy stable, and I have never experienced these problems
you're mentioning here.

Re: [beagleboard] Re: 4D Systems 4DCAPE-70T, no display

[Brian Yee]

Yes, I double checked the insertion of the board.  Also, the LED's came on
and the reset and power switches worked ok.
I also flashed the latest image from the BeagleBoard.org site:
BBB-eMMC-flasher-2013.09.04.img.xz
with the same results.  The images suggested earlier (
BBB-eMMC-flasher-v2013.06-2014.01.03.img.xz)
had some errors
when I tried to unpack them with 7-Zip.

I may try ordering a cape from another vendor (Circuitco) and see if that
has the same problem.  I am presuming it
uses the same driver.

TIA for the dialog on this from everyone.

Brian

Which version of u-boot are you using? Could it not also be the ethernet
drivers? I would try updating to the latest u-boot version and see if
you're still having issues.

[beagleboard] TFTP from u-boot: slow and buggy

[lee]

I have a setup that loads u-boot onto the BBB over the serial port, and 
then tells u-boot to load the .dtb and kernel from a local TFTP server. 
Loading the small .dtb file works perfectly (although slowly), and 
succeeds. Loading the kernel takes too long, causes lots of retries, and 
finally errors out. If I manually get the kernel from that same TFTP server 
onto my laptop, it loads in about 11 seconds--over wifi--so the server is 
working fine. It's just u-boot's TFTP client that seems to be causing the 
errors. I have seen other messages around the net advising changing the 
server's block size to 1468, which I did, and telling u-boot to turn dcache 
off, which isn't an option anymore, but it still fails.

Has anyone actually got this working? Which tftp server are you using, and 
what parameters? Is there a patch to u-boot that might fix its client?

[beagleboard] Re: Build a QT/11 application for beagleboard black by cross compiling from ubuntu

[dlewin555]

I don't understand when you talk about "deployed" did you mean "on the BBB" 
?
FYI I've also tried from the same blog you linked and have been tried it 
during days
with Angstrom and never succeeded . 
Even if I've read many post about it  here Qt on the BBB seems to be a hard 
path.
Or maybe we both missed a tutorial that should be officially posted 
somewhere

[beagleboard] Windows android adb issues

[Doug Nappier]

I am working with Android Jelly bean and am having some adb issues when it 
comes to Windows 7. I can not get windows 7 to recognize the device as an 
Android device and can not find it with adb. When I boot into my linux host 
machine I can use adb to find the beagleboard.  

I ran lsusb on the device in my linux host and got the following output:
Bus 001 Device 011: ID 18d1:9018 Google Inc

I read in the TI ADB install 
guide that 
you need to add the following lines to you the .inf file:

%SingleAdbInterface% = USB_Install, USB\VID_18D1&PID_9018
%CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_9018&MI_01

When I go to my device manager, where the device is mistakenly being 
established as a mass storage device, and attempt to point Windows at this 
new .inf file it gives me the error "Windows could not find the driver 
software for your device"

Does anyone have any ideas how to fix this.

not getting an RTS when I open my serial port.

Re: [beagleboard] Could someone help me troubleshoot a paid program called screenconnect?

[Jacob Bell]

all this help is appreciated, but is over my head, even the reporting mono 
to debian group and mono group I dont follow.  I will try to get the 
screenconnect people to help acomplish this.  I am just a user that wants a 
low powered cheap computer to run screenconnect and debian has other nice 
packages I could use for other things so I can multi-purpose it for greater 
value and usefulness.  I at this time am forced to return to the stock 
Angstrom 6.20 image and reinstall screenconnect there where it works 
decent.  It just isnt any fun to have to find how to tweak the image with 
all that garbage (cloud9, Bonescript, etc) going and hogging resources in 
one way or the other.  Angstrom does not cut it when it comes to other 
guides to install such and such to work because nobody uses angstrom,  most 
guides are in debian or mostly ubuntu.

The device tree overlay is wrong. Use the one supplied with your
distribution or change the line:

 0x190 0x13/* P9_31 = mcasp0_aclkx.spi1_sclk ,
OUTPUT_PULLUP | MODE3 */

to

 0x190 0x33/* P9_31 = mcasp0_aclkx.spi1_sclk ,
INPUT_PULLUP | MODE3 */

I don't know anything about the IOoo library but I know that libsoc
works well for interfacing with the SPI bus.

Not sure what your issue is. You may need to request and RMA and get it
looked at to see if there is a HW issue. 1 time out of 100 seems to

Yuk!  It still might be worth a try as that was nearly two years ago.  It
might also be worth going back to the mono developers (non-debian) list and
asking there.

According to the Debian package pages, mono is available for ARM, but only
armel not armhf.  It might be worth going to the mono list for debian at
pkg-mono-gr...@lists.alioth.debian.org and asking if it is simply that
no one has gotten around to building it for armhf, or if there is some 
reason (like the JIT has some assembler code which is endian dependant and
no-one has rewritten it for armhf).  If there is a call for it they might
try building it for you.

[beagleboard] Could someone help me troubleshoot a paid program called screenconnect?

[Jacob Bell]

I bought a program called ScreenConnect at screenconnect.com.   Anyone can 
freely use this for one month with trial key which immediatly after 
registering you get your key.  This supposed to work with the Beagle Bone 
Black.  

The problem is that I can get it working in the default Angstrom 6.20 image 
but if i flash to newer image it does not work, nor does it work in any 
version of ubuntu or debian.  My perferred choice is debian 7.3.  

The install scripts for this program spits out an error:

./install.sh: line 248:mono: command not found


--- So screenconnect support responded with this after they SSH into my 
beaglebone and saw the same problem and was not sure how to fix it:

Hey Jacob,

Jake said that the following command and, more importantly, the system 
response below form the crux of the problem:

root@arm:~/ScreenConnect_4.1.5867.5115_Install/Installer# ldd 
mono_linux_01_armv7 
not a dynamic executable

Jake said that you may want to ask on the forum with the particular command 
as the basis.



- so im only doing what they ask.  any help would be greatly 
appreciated.

Re: [beagleboard] Re: Touchscreen Jitter / Jumping on Beaglebone Black LCD Capes

[Micka]

OK,

Maybe it's time we work together and try to fix this bug. *A beaglebone
black that doesn't support correctly the touchscreen, it's a SHAME !*

So I'm going to try to fix it by myself =>

I prefer to put my conclusion here, because I don't hink everyone has the
time to read my research :




 *1) Presentation of the BUG*



   - When you touch the screen repeatedly ( up and down up and down ) the
   bug seems to happen ! ( rarely, but it does )
   - When you touch the screen continuously, you can see that sometime the
   mouse go far away from your finger .


*2) The driver*

The name of the driver is TI - TSC ADC (Touschscreen and analog digital
converter)

It's easy to find the source of this driver =>
drivers/input/touchscreen/ti_am335x_tsc.c

 *3) The  Interesting part*

 The interesting part of this driver, is this function :

static void titsc_read_coordinates(struct titsc *ts_dev,

u32 *x, u32 *y, u32 *z1, u32 *z2)

{

unsigned int fifocount = titsc_readl(ts_dev, REG_FIFO0CNT);

 unsigned int prev_val_x = ~0, prev_val_y = ~0;

unsigned int prev_diff_x = ~0, prev_diff_y = ~0;

 unsigned int read, diff;

unsigned int i, channel;

unsigned int creads = ts_dev->coordinate_readouts;

*z1 = *z2 = 0;

if (fifocount % (creads * 2 + 2))

 fifocount -= fifocount % (creads * 2 + 2);

/*

 * Delta filter is used to remove large variations in sampled

 * values from ADC. The filter tries to predict where the next

 * coordinate could be. This is done by taking a previous

 * coordinate and subtracting it form current one. Further the

 * algorithm compares the difference with that of a present value,

 * if true the value is reported to the sub system.

 */

for (i = 0; i < fifocount; i++) {

read = titsc_readl(ts_dev, REG_FIFO0);

 channel = (read & 0xf) >> 16;

read &= 0xfff;

 if (channel < creads) {

diff = abs(read - prev_val_x);

 if (diff < prev_diff_x) {

prev_diff_x = diff;

 *x = read;

}

prev_val_x = read;

} else if (channel < creads * 2) {

diff = abs(read - prev_val_y);

if (diff < prev_diff_y) {

prev_diff_y = diff;

*y = read;

}

 prev_val_y = read;

} else if (channel < creads * 2 + 1) {

 *z1 = read;

} else if (channel < creads * 2 + 2) {

 *z2 = read;

}

}

}



So did you watch this code ? Well, In my case, I understand why there is
this huge bug !

We have to admit, that sometime there is noise during the transfer of the
coordinate between the LCD and the driver.

So, this code is supposed to filter any of noise with this :



diff = abs(read - prev_val_x);

if (diff < prev_diff_x) {

prev_diff_x = diff;

*x = read;

}

prev_val_x = read;


Well, I'm sorry, but if the noise happen, you should not save the noise
value has the last position (correct me if I'm wrong ?) .

So, I changed the code with something like that :

 if (channel < creads) {
printk("raw x=%d\n", read);
diff = abs(read - prev_val_x);
if (diff < prev_diff_x) {
printk("x=%d & diff=%d\n", read, diff);
prev_diff_x = diff;
*x = read;
prev_val_x = read;
}

} else if (channel < creads * 2) {
printk("raw y=%d\n", read);
diff = abs(read - prev_val_y);
if (diff < prev_diff_y) {
printk("y=%d & diff=%d\n", read, diff);
prev_diff_y = diff;
*y = read;
prev_val_y = read;
}

} else if (channel < creads * 2 + 1) {
*z1 = read;

} else if (channel < creads * 2 + 2) {
*z2 = read;
}

Also, it's important to note that this function is called by the
function irqreturn_t titsc_irq:
I put a printk to be noticed when the function is called :

static irqreturn_t titsc_irq(int irq, void *dev)
{
struct titsc *ts_dev = dev;
struct input_dev *inp

Yeah.. the "5_00_00_01" drivers are useless for anyone not running
