Re: [beagleboard] OMAP related patches to be applied on top of vanilla Linux Kernel

[neo star]

So for my understanding https://github.com/beagleboard/linux is the
location of kernel used in BBB

and

3.8 (current stable)
https://github.com/RobertCNelson/linux-stable-rcn-ee/compare/v3.8.13...3.8.13-bone66

3.14 (next stable)
https://github.com/RobertCNelson/linux-stable-rcn-ee/compare/v3.14.19...3.14.19-ti-r25

contains patches still not in the main line kernel AKA development branch.

Re: [beagleboard] Buildroot issue

[Jai Shiv]

Hi Frank

All the binaries under output/host/usr/bin having this prefix
arm-buildroot-linux-uclibcgnueabi-  .
For example for gcc it is like :
arm-buildroot-linux-uclibcgnueabi-gcc

So in Path variable i added the path of output/host/usr/bin folder.

And While compiling anything for arm target i gave CROSS_COMPILE=
arm-buildroot-linux-uclibcgnueabi-

But it's giving me same error.
In my another build machine there are symlink created for all binaries
under output/host/usr/bin folder

For example : for gcc there is one binary arm-buildroot-linux-uclibcgnueabi-gcc
and there is corresponding link present like

arm-linux-gcc ->arm-buildroot-linux-uclibcgnueabi-gcc

So while cross compiling a arm program I usually give arm-linux- and it's
work fine .


Hope You understood now.

[beagleboard] Building for BeagleBoard XM and Preparing Bootable SD card for it.

[softy]

Hi All, 
This is my first Question and kinda getting started Qs.I was searching for 
building for *BeagleBoardXM *and preparing SD card for it.I have came 
across numerous links (once by beagleboard, one by IBM, and many more 
blogs) ,But I am not able  to figure out which  one to follow.Is there any 
official page for all the instructions which could furnish me with the 
below things : 

(1) Building Package - Bootloader,Kernel,filesystem(and what ever 
necessary) for *BeagleBoardXM *to boot Linux.
(2) Creating a Bootable SD card for it and boot it with the above package.
(3) Any official page for flashing Android on 
BeagleBoardXM(System.img,userdata.img,boot.img,etc)

Please note in the past I have fair experience of building/flashing and 
booting of android(4.4.X ) on PandaBoard ES rev B.There is a readme inside 
the device/ti/panda which tells from where to download the sources , how to 
build and how to flash the boot-loader,xloader,boot.img,userdata.img for 
the Android.I am looking for the similar thing for the Android for 
BeagleBoardXM.
Eagerly looking for a slap to my post to do something about this.

Thanks and Rgds,
S

[beagleboard] Re: Getting comms going on UART1

[jfsbac]

Hi,

Not and expert here, but I did manage to get communication with a device 
connected to UART1.  What do you have connected?  If there is nothing there 
your transmit data will just go off into space.  To see data come back you 
would have to have a device in loopback mode, or at least the Tx connected 
to the Rx.  

I am running the Debian image, and used the ADAFRUIT-UART2 overlay.  It 
shows up as ttyo1 (thats oh one, not zero one).  I have a Sparkfun MAX3232 
module that translates the 3V TTL to RS232 which goes to a little micro 
that responds to commands like "/sh/s" and returns some text.  I use screen 
to type the text commands until I get my C program working on the BBB, or 
try javascript.  Oh, there are also two Zigbee modules in between the micro 
and the BBB creating a wireless RS232 link.

Hope this helps,

Jonathan

I'm not sure that I understand which binaries that you'd like. Host
tools such as the compiler can be found in the output/host/usr/bin
directory.

That does not sound like the right prefix. You didn't say what
buildroot configuration that you were using so I can't say for sure.
However, it's often longer like arm-none-linux-gnueabi- or similar. If
you look in your output/host/usr/bin directory, you should see what it
is.

Also, why don't you let Buildroot build uboot? It will set the
CROSS_COMPILE prefix correctly.

I'd recommend updating your PATH rather than creating symlinks to the
host tools.

Well you can look this up yourself, as everything is located here:

https://github.com/beagleboard/linux

3.8 (current stable)
https://github.com/RobertCNelson/linux-stable-rcn-ee/compare/v3.8.13...3.8.13-bone66

3.14 (next stable)
https://github.com/RobertCNelson/linux-stable-rcn-ee/compare/v3.14.19...3.14.19-ti-r25

This of course, doesn't showcase the fact you can run mainline just
fine, everything above is patches being submitted/worked on/etc.

[beagleboard] OMAP related patches to be applied on top of vanilla Linux Kernel

[neo]

Hi

   1. I like to know the location of OMAP related patches like for example 
   GPIO drivers, UART, I2C are maintained and updated ? This i am asking 
   because i like to know how they are written.
   2. I am assuming that when an updated kernel for BBB is released 
   maintainers take the vanilla Kernel and apply the above patch for these 
   drivers and release it. This is correct ?
   
Thanks

Re: [beagleboard] Re: 3 proposed patches for next 3.8.13-bone5x update

[Alexander Hayman]

I'm using wheezy. GNU sed version 4.2.1.  I see what's happening now.
It looks like the uEnv.txt doesn't have quotes around the kernel version
at all, so there shouldn't be any inner quotes.  The only reason my
kernel "update" worked was because the kernel version was the same, so
the sed didn't need to catch a match and update the uname_r.

It looks like single or double outer quotes work fine.

[beagleboard] Cannot read data on serial UART4 ...

[philippe . frossard]

Hi,
I'm using Linux version 3.8.13-bone40,
On board-name A335BNLT / Revision 00C0,

My slots,
 0: 54:PF--- 
 1: 55:PF--- 
 2: 56:PF--- 
 3: 57:PF--- 
 4: ff:P-O-L Bone-LT-eMMC-2G,00A0,Texas Instrument,BB-BONE-EMMC-2G
 5: ff:P-O-- Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI
 6: ff:P-O-- Bone-Black-HDMIN,00A0,Texas Instrument,BB-BONELT-HDMIN
 7: ff:P-O-L Override Board Name,00A0,Override Manuf,BB-UART1
 8: ff:P-O-L Override Board Name,00A0,Override Manuf,BB-UART2
 9: ff:P-O-L Override Board Name,00A0,Override Manuf,BB-UART2-RTSCTS
10: ff:P-O-L Override Board Name,00A0,Override Manuf,BB-UART4
11: ff:P-O-L Override Board Name,00A0,Override Manuf,BB-ADC

I have no problem with UART1 and UART2,
I connected TX to RX on UART4,
I can send data on UART4 (TX) "echo 1 > /dev/ttyO4",
But with "cat /dev/ttyO4" the data is printed out in loop with a lot of 
data ...
The buffer on UART4 seem to be not managed correctly ...

Do you have a solution ?!

My BB-UART4-00A0.dts,

compatible = "ti,beaglebone", "ti,beaglebone-black";
part-number = "BB-UART4";
version = "00A0";
exclusive-use = "P9.13", "P9.11", "uart4";

fragment@0 {
target = <0xdeadbeef>;

__overlay__ {

pinmux_bb_uart4_pins {
pinctrl-single,pins = <0x70 0x26 0x74 0x6>;
linux,phandle = <0x1>;
phandle = <0x1>;
};
};
};

[beagleboard] Is it possible to root an Android in beaglebone black?

[Caio Vinicius]

I'm using an modify image of Android distributed by Chipsee (Because i'm 
using an Capacitive LCD of them).

But now I want to access the GPIOs, SPIs, I2C and others devices. But i 
need root access for that.

How could I root my Android?

[beagleboard] Re: question about I/O expansion

[k . deganck]

Dear,

We have a campaign running on Indiegogo : http://igg.me/at/kunio
We offer a robust and modular I/O expansion system, up to even hundreds of 
I/O or more.
It uses a very simple interface ( like SPI with a few bits. )
We will also offer analog in and outpus in the near future, within the same 
concept.
If you have any questions, just let me know.
I hope this could help you.

regards, Koen

[beagleboard] serial port with LCD chipsee 4.3

[giorgioazzoli]

Hello
I have the BBBlack and the chipsee display 4.3" C5-BBB-EXP43
I have the WINCE OS working, it is in "bundle" in the chipsee CD.

I connected the UART2
GND
RXD_2
TXD_2 

To  RS232 device.

On the BBB, i compiled an application that works on other windows mobile/CE 
devices with the serial port.
The same application is running on BBB with the 4.3" display 
I set COM1, at 115200 (like the connected device) but i can not see data.

Can you help me ?

This works on wheezy:

sed -i -e "s:uname_r=$older_kernel:uname_r=$version:g" /boot/uEnv.txt

Selecting previously unselected package linux-image-3.14.19-ti-r25.

I'll fire up jessie/trusty/utopic and make sure it works there too.

The only intellectual property rights violated are those of our common

Re: [beagleboard] Re: 3 proposed patches for next 3.8.13-bone5x update

[Alexander Hayman]

Hmm, this didn't fix the problem.

Preparing to replace linux-image-3.8.13-bone66 1cross (using 
linux-image-3.8.13-bone66_1cross_armhf.deb) ...
Unpacking replacement linux-image-3.8.13-bone66 ...
Setting up linux-image-3.8.13-bone66 (1cross) ...
update-initramfs: Generating /boot/initrd.img-3.8.13-bone66
zz-uenv_txt: Updating /boot/uEnv.txt [uname_r=3.8.13-bone66]
sed: -e expression #1, char 24: unterminated `s' command
run-parts: /etc/kernel/postinst.d/zz-uenv_txt exited with return code 1
dpkg: error processing linux-image-3.8.13-bone66 (--install):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 linux-image-3.8.13-bone66

However, a colleague found this solution, which works fine:
sed -i -e 
's:uname_r='"'"'${older_kernel}'"'"':uname_r='"'"'${version}'"'"':g' 
/boot/uEnv.txt

Re: [beagleboard] Re: Rev. B and Rev. C board availability

[anupsingh chandel]

Dear Jason,
 
Thank you for all the documents and such an amazing product. I want to use 
BBB in my design as an LCD driver and USB host. Can I use it..? But i don't 
need other componets on the PCB apart from my requirement. Can I develop 
PCB using the gerber provided? will there be any intellactual property 
rights violation?
 
Please let me know.
 
Thank & regards,
Anup.

Re: [beagleboard] Home Automation Cape with KNX/EIB, Enocean and four dedicated Onewire-Busmasters (IBB-Cape)

[Robert Budde]

Sorry for the pictures, I logged out of the forum and checked but obviously 
it still recognized me as a member for some reason.

Pictures of cape: 
https://plus.google.com/photos/109748949078391340253/albums/6062167373953605841

I do not recommend using the RTC because it is in most cases a waste of 
money as long as the BB is connected to the Internet. Technically there is 
no reason not to fit it, it actually works as expected.

Regards,
Robert
