Re: [beagleboard] Re: Availability - how come nobody has any BeagleBone Black to sell?

Maybe the world is a little bigger than Marietta ;-)

Distributors in Italy (RS components, Mouser, Farnell) are still without 
boards. RS says you can reserve boards for April...

 Gerald,

 I see on http://www.elinux.org/Beagleboard:BeagleBoneBlack#

 I have had Qty 1 on back-order from Digikey since Jan 13th. I would

 Any clues as to what is happening here?

[beagleboard] How to setup ethernet over USB with Debian

[Chris Frankowski]

I'm using this image:
https://rcn-ee.net/deb/flasher/wheezy/BBB-eMMC-flasher-debian-7.3-2014-01-24-2gb.img.xz

I was able to get this working with Angstrom following these instructions:
http://lanceme.blogspot.ca/2013/06/windows-7-internet-sharing-for.html

specifically:
route add default gw 192.168.7.1 
echo "nameserver 8.8.8.8" >> /etc/resolv.conf

But it's not working for me with Debian.

ping 192.168.7.1 works
ping 8.8.8.8 does not
ping google.com does not

Other details, not sure if useful:

[beagleboard] OSX not detecting BBB with Android on USB

[Malcolm Groves]

Hi,

I'm successfully booting into Android on the BBB (using the image at 
http://icculus.org/~hendersa/BBB_JB_Android_3_8_13.img.bz2), and can 
navigate to Settings | Developer Options and enable USB Debugging. 

However, OSX Mountain Lion (10.8.5) doesn't recognise it when I plug it 
into the USB port. 

I've read a few pages on how to make it show up for linux and windows, but 
the consensus for OSX is "it should just work". 

Any ideas?

Cheers
Malcolm

Re: [beagleboard] Beaglebone Black Ethernet Phy Not Detected on Boot.

[sunvale]

Does the C24 value change in revision A6A suppose to fix this problem? I 
still got this issue on my two BBB A6A. Do we need to increase C24 further, 
or have it removed completely since U16 is added?

  Hello,

 I have noticed very rare cases (~1/50) of the ethernet phy on the 
 Beaglebone Black not being detected on boot, and requiring a hard reset 
 (as 
 opposed to calling 'reset' from the command line) to get it to work/be 
 detected again.

 This problem has been mentioned in a couple of other threads (below) 
 concerning different topics (i.e. problems getting the BBB to boot, and 
 the 
 ethernet phy 'dying' some time after initially working fine), with no 
 solution/workaround for this specific problem being suggested - so I 
 thought I'd start a thread specifically for it.
 https://groups.google.com/forum/#!msg/beagleboard/
 Vp4pxwHm8BU/Iaw3p5xm0MoJ
 https://groups.google.com/forum/#!topic/beagleboard/aXv6An1xfqI

 In the first thread mlc/Mike discussed his response to the problem as 
 follows:












 *"I had issues with the network not coming up on boot, and it was 
 traced down to problems with the SYS_RESETn line.  I had a level 
 translator 
 connected to SYS_RESETn, to drive a 5V chip. It was powered by a 5V rail. 
 If the 5V rail powered up "differently" than the 3.3V rail (not sure of 
 the 
 exact relationship), I guess it  pulled the SYS_RESETn line to weird 
 levels 
 that affected the network chip but not the main processor. I'm now using a 
 GPIO to drive the external 5V chip now, instead of the SYS_RESETn 
 line. Anyway, the moral is be very, very careful with SYS_RESETn, because 
 it  can cause hard-to-trace problems with networking.*"

 I see that the A6 Revision of the Beaglebone Black has some changes to 
 the SYS_RESETn line:

 "*Based on notification from TI, in random instances there could be a 
 glitch in the SYS_RESETn signal from the processor where the SYS_RESETn 
 signal was taken high for a momentary amount of time before it was 
 supposed 
 to. To prevent this, the signal was ORed with the PORZn (Power On reset).*
 " (http://elinux.org/Beagleboard:BeagleBoneBlack#
 Revision_A6_.28Production_Version.29)

 Is it likely that this modification will improve/resolve the issue I am 
 seeing with the ethernt phy not resetting/powering-up correctly?, seeing 
 as 
 the SYS_RESETn signal also feeds into the nRST pin on the ethernet phy 
 (The 
 SYS_RESETn line is left untouched in my application).


 Some additional observations from dmesg concerning this use:

 On a good phy boot I see the following:
 [2.810749] davinci_mdio 4a101000.mdio: davinci mdio revision 1.6
 [2.817206] davinci_mdio 4a101000.mdio: detected phy mask fffe
 [2.833517] libphy: 4a101000.mdio: probed
 [2.837871] davinci_mdio 4a101000.mdio: phy[0]: device 
 4a101000.mdio:00, driver unknown

 Followed later by:

 [   21.301166] net eth0: phy found : id is : 0x7c0f1

 On a 'bad phy' boot I see the following (differences highlighted):
 [2.806763] davinci_mdio 4a101000.mdio: davinci mdio revision 1.6
 [2.813213] davinci_mdio 4a101000.mdio: detected phy mask *fffb*

[beagleboard] Re: debian: test images (2014-01-10)

[Louis McCarthy]

I'm still working on testing this image, but thought I would comment on a 
couple things before they slipped my mind.

I've flashed the eMMC on A6 and A6A BBBs and have run the flasher image as 
a live system by removing the flash-eMMC.txt file. 

The BB-BONE-AUDI-01:00A1 cape does not have a driver compiled into the 
kernel (A0 is there).
The LCD backlight frequency of 50 is causing audible whine 
(BB-VIEW4/LCD7/BB-VIEW7) when the brightness is less than 100%. I fixed 
this by changing the frequency defined in the dts file (32768 works, but I 
just chose that randomly). Which repository are these being pulled from? I 
can fork that, make changes, and issue a pull request if that would help.

With the LCD7, I don't detect much, if any, of a change between the two 
versions of touchscreen drivers. I am not saying that we should discard the 
new version, but that the new version doesn't negatively affect the system.

My thoughts, with respect to networking, are to make it easy to get a 
wireless connection up and running. Wicd is pretty good at that, but I 
notice that every 8 to 20 minutes the wireless connection is dropped. That 
could be the AP I am connected to, so I will continue to test with other 
APs. I still need to test a couple more USB adapters too.

Another comment is the screen blanking. I noticed that the LCD7 goes white 
instead of just blanking to black. Not a problem, just noticed the change. 
But in trying to disable the power saving, I open the screen saver settings 
and am greeted with a warning message that the XScreenSaver daemon isn't 
running. This may give new users the impression that something is broken in 
the image. Is there another place to disable the screen blanking timer? 

Thanks,
Louis

 First, are you sure the option is being passed to the kernel?  What 
 does 
 "cat /proc/cmdline" return? 

 Second, have you tried the 'e' flag while also specifying a resolution? 
  Try something like: 

 kms_force_mode=video=HDMI-A-1:1024x768@60e 

 ...in /boot/uboot/uEnv.txt.

Re: [beagleboard] machinekit on BBB - how to force enabled HDMI hardware from cmdline

[doog]

in the uEnv.txt file there's a line starting with "optargs="
Add to the end of that line:
" video=HDMI-A-1:e"

make sure there's a space before the "video=." and this should force 
the enabling of the HDMI port.

Do you have the pullups on the board enabled, or disabled ?

Are you using 3.12 or later kernel ?  The driver for this was only merged in 
3.12.

Did you 'modprobe htu21' or is the driver compiled into your kernel ?


I've come across a few things recently that i2cdetect doesn't see, but if you 
access them directly they work fine.

Re: [beagleboard] Re: Attention if order LVDS-Board from chalk-elec!!!

[klimets]

Hi again,

I reached Malaysia last weekend. They have national holiday (Chinese New 
Year), and office was opened today only. Here is short report:

   1. ChalkElec just moved to new bigger building, most of stuff from old 
   office still in boxes. They are unpacking now, going to start operation 
   next week. 
   2. They also bought new SMT equipment. I saw new PnP machine and 
   semi-automatic stencil printer. It should solve bottleneck with manufacture 
   speed, and they will finally have stock open.
   3. I inspected today their order processing system. Looks like it has 
   bug, because some orders are missed in system, and they exist in PayPal 
   only. So, guys were not aware about orders before customers started to 
   write emails or open PayPal claim. I will check this in more details this 
week, 
   then we will try to fix it. Regarding current customers, I requested 
   ChalkElec to provide 2 lists with orders - one from PayPal, and another 
   from internal order processing system. I will write simple program to 
   compare both to find out missed orders, and we will process them manually. 
   4. In my last post I asked you to send your claims directly to me. So 
   far I got just one claim. I really hope that this problem is pretty rare.

I see that guys really trying to do their best. Yes, they have some 
problems with planning, order processing, and support. But they are 
learning to make business. This is tough period for them, when business 
grows faster than they expected. We at ZetaOri will keep an eye on them and 
will try to pay more attention to support and advice them on key business 
points. 

For any future problems like this you can send claims directly to my email 
- I will take care to investigate and help with solving.

Should set the clock.  Note that although the BBB has an RTC, it has no

[beagleboard] uboot/drivers/mtd/nand: how to enable on-die-ecc on a flash chip / how to send command to flash chip

[star]

Can someone please give me a hint howto send a command to a flash chip, in 
my case to enable on-die-ecc?

I found at some place how to read the byte, but I don't understand how to 
modify it for write (chip->write_byte isn't the way):


* ## */
/* MICRON: Test on-die ECC status; return: 1/On or 0/Off */
int test_on_die_ecc(struct mtd_info *mtd)
{
struct nand_chip *chip = mtd->priv;
int addr = 0x90;
uint8_t data, data_;
chip->cmdfunc(mtd,NAND_CMD_GET_FEATURES,addr,-1);
ndelay(2000);
data = chip->read_byte(mtd);
return((data & 0x08) ? 1 : 0 );
}


---
Can you help me what do I have to do send this below?

ECC can be enabled using the following sequence:
EFh(cmd)-90h(addr)-08h(data)-00h(data)-00h(data)-00h(data)-wait(tFEAT).

ECC can be disabled using the following sequence:
EFh(cmd)-90h(addr)-00h(data)-00h(data)-00h(data)-00h(data)-wait(tFEAT).

Re: [beagleboard] Reading a Quadrature Encoder connected to a Beaglebone [black]

[Willie Warke]

UPDATE: I figured out the issue - I needed to burn a fresh image onto the 
SD card before the script would copy the files. I would have appreciated 
some sort of error message :P Anyways, using the manual .dtb file copy 
mentioned previously, I got the driver loaded and the device tree loaded 
for eqep0. However, I'm getting no useable output from the position 
variable. While troubleshooting, I began to wonder if the eQEPs will work 
with only Ain and Bin connected (all my encoder has). Is there a setting 
that needs to be changed to ignore INDEX and STROBE? Just wondering, though 
I'll probably figure out how to get it operational sooner or later.

[beagleboard] New case for BeagleBone Black from SB Components

[componentssb]

Hi

Just in case anyone wants an alternative to the standard BeagleBone Black 
cases, I thought I'd post this link to a new case for the BeagleBone Black 
from SB Components: SBC BeagleBone Black 
case


As you can see it comes in a number of different colours.

[beagleboard] Interfacing htu21 over i2c with Beaglebone Black

[Rushi Desai]

I got an HTU21D temperature and humidity breakout board from Sparkfun 
(https://www.sparkfun.com/products/12064). Since I'm a novice at 
electronics I'm unsure if I've made an error in connecting the device or 
there is some device driver issue. I connected the breakout to my 
beaglebone black as follows:

+ : Pin 3 (VDD)
-  : Pin 1 (GND)
DA : Pin 20
CL  : Pin 19

The datasheet says 3.8V maximum and since the VDD is 3.3V, I thought no 
logic level converter would be necessary. Running i2cdetect doesn't show 
anything connected. The output is as follows:

# i2cdetect -r -y 1
 0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:  -- -- -- -- -- -- -- -- -- -- -- -- --

50: -- -- -- -- UU UU UU UU -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --

I tried to initialize the driver by running:

# echo htu21 0x40 > /sys/class/i2c-adapter/i2c-1/new_device

This is what I see in dmesg:

[215690.914098] i2c i2c-1: new_device: Instantiated device htu21 at 0x40

But there are no directories created under '/sys/bus/i2c/drivers' 
corresponding to this driver.

[beagleboard] lcd cape and kernel 3.12

[larochelle . brian]

We have a custom LCD cape working great with kernel 3.8.  I'm hoping I will 
have better results with sgx on kernel 3.12, so i'd like to start testing 
it.  I ran into compatibility issue with our device tree file.  I resolved 
a few issues, but haven't gotten it sorted out correctly.  It doesn't 
appear any other cape's dts files have been ported as yet.  

Does anyone know of any reference material you could point me to that would 
be useful?

Thanks

Re: [beagleboard] Re: QT for Beagleboard xM

[ozkannn01]

Just a quick note for the one running Ubuntu on target:
 - Install libqt4-core, libqt4-dev, libqt4-gui and qt4-dev-tools by 
using synaptic package manager on BB-xM
 - qmake -> generates Makefile automatically
 - Qt Designer -> GUI layout and design
 - Qt Creator -> a cross-platform IDE

As an example if you have a main.cpp the following command lines build the 
executable on BB-xM
 - qmake -project
   // creates project file
 - qmake
   // creates Makefile
 - make
   // compile and build main.cpp
 - run the executable generated in the folder.

Regards,
Ozkan.

No dependencies are required for the kernel, and the kernel interface is
standard enough you can swap out versions without having to recompile
everything that sits above the kernel.

So yes, you can just swap out the kernel.  Especially a 3.8.13 kernel
for a 3.8.13 kernel patched with Xenomai!  They are virtually identical.

Re: [beagleboard] I can't make BBB rev A5C & LCD7 Cape rev 3 work together :-(

[DoctorP]

Thanks a lot, Hieu. 

I can't assure 100% but it seems that you were right. I have cut the 
problematic pins on the connector and now it is working fine. I've booted 8 
times without problems. 

Thanks again!

Manuel.

Re: [beagleboard] Xenomai master -> BBB RCNelson 3.13-bone5 kernel patches

[David Lewin]

I think I've misunderstood finally, you were explaining me how to build
tools , so indeed : I've reproduced the operations manually as from
the shu script

Besides, from the Readme :

> first run (to setup baseline tree): ./build_kernel.sh
> then modify files under KERNEL directory
> then run (to rebuild with your changes): ./tools/rebuild.sh


seems what you were talking about, therefore my modifications will be in
the 2nd part.

just grab one of RCN's eMMC flasher images
> That and swapping out the kernel gets you a working Xenomai system.


Then, I only copy the built xenomai linuxcnc kernel onto this RCN's eMMC
image ? no dependency (libs, ...)

[beagleboard] i2c4 disabled in kernel

[Maxim Podbereznyy]

Hi!

does anybody know why i2c4 disabled in kernel? Specifically I try to bring
up 3.7x to my device and found that the function omap_register_i2c_bus()
hangs when the bus number is 4. Digging into code shows that this check is
true
BUG_ON(bus_id < 1 || bus_id > omap_i2c_nr_ports());
because omap_i2c_nr_ports() returns 3.

any comments are appreciated

[beagleboard] Wifi wpa2-psk configuration

[Nuno Valverde]

I have never worked with conman. Is there any reason for using this software 
for managing the conections?  
However i can try to help you if you use the interfaces files for the 
configuration.
