[beagleboard] Device tree load time [BBB]
Hello everybody. I have a project where I am using the BEAGLEBONE Black Revision C with the latest official Debian image. I configured the device tree to use UART1 including using *RTSn* pin. Everything is running properly and the *RTSn* pin is working well. However, unfortunately, until the device tree is read and peripherals configured by the kernel, the RTSn pin it stays low. The system takes 14 seconds to set the pin as *RTSn* and put it in HIGH state, the default state for communication. Does anyone know any way to configure that device more quickly? Or to force this pin and get high state before? P.S: I can *not* change the hardware! -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

I do understand what you are doing with these high level steps you laid

you are going to include them as patches? Is the patch already available?
Where can I find it? Thanks!

I've got bluetooth finally working. Andrew, what would be the best

Patches generated by git are fine. If you know the major parts that
you patched, you can also cd into the appropriate directory and do a git
status to show you which files have changed and just mail me those files
(hendersa (at) icculus.org). For subdirectories that are completely new
(like the Bluez added into external/), you can just tar up the directory
and send it to me. My understanding is that you added in Bluez, modified
the build scripts to pull that external project in, patched bionic, and
changed the kernel config to build in Bluetooth. Does that sound about
right?
Ok I'll start work on getting it over to you. Basically you are
correct. Here are the steps at a high level:
* Add bluez repo to the manifest and told it to not pull bluedroid.
* Patched bionic, although I see bluez has a patched bionic in a repo
for 4.4, maybe I can just change the manifest.
* Built bluetooth kernel modules from backports, 3.8 is too old
* Added insmod commands to init.{ro.hardware}.rc on boot and added
import init.bluetooth.rc
* Commented out qemu=1 check for bluetooth.
* Had to manually move some libraries to /system/lib/hw/ from
/system/lib/

I've tried it maybe a dozen times now with both a 5V and USB power supplies. I have flashed other images on my BBB just fine before, and swear I am following the same procedure. I am: What was the full image name of the file? 1. Inserting the microSD with the image, 2. Holding down the boot switch 3. Applying power 4. Waiting for the user LEDs to all turn on then start to flash 5. Release the boot switch. The LED activity looks active for only a couple minutes then it switches to the regular heartbeat pattern, and it never goes to all 4 on again and shut down like when flashing other images even if I wait hours. Was it doing they cylon pattern? The 2015-03-01 flasher should always shutdown when done... I have found that all its doing is booting from the microSD card. If I don't power down after the flash attempt, keep the microSD installed, and check version, it indicates I'm running version 2015-03-01. If I power down, remove the card, then power back up, the old image is running. Did something change with the flashing procedure? I'm guessing there is something I have to fiddle with on the image to make this work. I'm comfortable writing code in C, C++, C#, and Java, but I'm a newbie when it comes to Linux.

Re: [beagleboard] Trouble flashing 2015-03-01 Debian image
I downloaded the image from here a couple days ago: http://beagleboard.org/latest-images md5: c848627722b7a5f7bc89791cc8949e3b File name: bone-debian-7.8-lxde-4gb-armhf-2015-03-01-4gb It's not doing the cylon scan. :-) I love that show by the way. According to the reference manual I am getting a heart beat and an activity indicator after only a couple minutes just like you do after a normal boot. From the reference manual: Page 26: USER0 is the heartbeat indicator from the Linux kernel. USER1 turns on when the microSD card is being accessed USER2 is an activity indicator. It turns on when the kernel is not in the idle loop. USER3 turns on when the onboard eMMC is being accessed. I'm relatively certain USER0 is flashing a double flash every second or so. USER2 is filckering. This occurs just a couple minutes after I release the boot button. Based on this and the fact that I get into Cloud 9 at this point and get 2015-03-01 version when I check, I am relatively certain its booting from the card, but not flashing.

[beagleboard] BeagleBone Black won't boot after wiring up LED strip w MOSFETs and separate 12V power supply
I wired up a circuit with an LED strip, 3 N-channel MOSFETs, and a separate 12V power supply, with the gate pins on the MOSFETS connected to I/O pins on the Beaglebone. When I didn't connect the circuit to the Bone ground, I apparently fried 2 boards. Neither will boot up. One gives a flicker on the power light and then goes off, and on the other the power light turns on, but the other LEDs don't flash and I can't get into either board. Here is the thread on the Adafruit forum with a photo of the circuit: http://forums.adafruit.com/viewtopic.php?f=8t=69691p=353330sid=eff0f5bd69bba9338e6f0ec2d7fa70c4#p353330 *The Adafruit support said that setup should not have hurt the board. * I checked the voltage on the gate pin on each MOSFET that was connected to the Bone and it was nominal (~200mA). Does anyone have any ideas on this? How could this have fried 2 boards? Thanks for any help. And PS I posted this earlier today but didn't see it show up in the forum.

My sample code is import sys from PySide import QtGui app = QtGui.QApplication(sys.argv) --- after this line i am getting that error message. sys.exit(app.exec_()) I did search and tried these steps to give a permission to the root user to use X server export DISPLAY=127.0.0.1:0.0 xhost local:root --- and getting this error unable to open display 127.0.0.1:0.0 I checked whether X server is available and got the message Server is already active for display 0. ps aux | grep X command also returned list of processes using X server. Could you please help me resolve this issue? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] PHY problem in 3.8.13-bone70
Hello, We were experiencing the already documented PHY not found issue in the black bone. The issue seems to be solved in 3.8.13-bone70, at least, we have been able to boot more than 80 times without a single error. Could anyone confirm that point?

Hello Ken Yang,
Sorry for very late. Here is link to compiled kernel on Google Drive
https://docs.google.com/file/d/0B7PmdsPeTtVOeHpHQ3dNX0pDMk0/edit?usp=sharing
.
** USB WiFi adapter must be plugged in before power-on.
1. extract content to root file system.
tar -xvf kernel.tar.gz -C /
2. Rebuild the module list.
depmod -a
3. Probe the module.
modprobe 8188eu
4. Generate encrypted WiFi pass phrase.
wpa_passphrase ssid passphrase
ex. My SSID=Sek, passphrase=sekranger
wpa_passphrase Sek sekranger
This command will output something similar to this.
network={
ssid=Sek
#psk=sekranger
psk=f5d1c49e15e679bebe385c37648d4141bc5c9297796a8a185d7bc5ac62f954e3
}
5. copy your encrypted pass phrase. For me, it's:
f5d1c49e15e679bebe385c37648d4141bc5c9297796a8a185d7bc5ac62f954e3
6. Use your favorite text editor to edit /var/lib/connman/wifi.config.
If it doesn't exists, create one.
7. Put this into wifi.config.
[service_home]
Type=wifi
Name=ssid
Passphrase=encrypted_passphrase
ex.
[service_home]
Type=wifi
Name=Sek
Passphrase=f5d1c49e15e679bebe385c37648d4141bc5c9297796a8a185d7bc5ac62f954e3

[beagleboard] Error gathering android sources
Hi all of you BBB devs! I have been working for four months on my capstone project, which is to create an Android Application that uses Google Maps API on the beaglebone black. I was able to flash Andrew Henderson's 3.8 kernel image onto my Beaglebone black using windows but during development realized it did not support OpenGL ES 2.0. I've been trying to create my own Android image that will contain the SGX drivers necessary for OpenGL ES 2.0 however while following the tutorial on http://processors.wiki.ti.com/index.php/TI-Android-JB-4.2.2-DevKit-4.1.1_DeveloperGuide. I am unable to even get past the Android Sources step. I have tried using the rowboat repo to construct the sources but everytime I try to run a 'repo sync' it is unable to fetch some of the projects which causes it to fail. Using the Pre-Packaged Sources also does not work because everytime I try to uncompress the .bin file I get an unexpected EOF error. I've downloaded the Pre-packaged sources four times now and every single one still gives that error. HALP PLZ, I'm so lost and google search has not given me much luck regarding these particular errors. I am trying to run this on Ubuntu 12.04 btw. If anyone is aware of a pre-built Android image with SGX drivers please message me ASAP, that also yields no results on google. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Re: Analog input sampling rate
Only 7 input pins (AIN-[0-6]) are connected to header pins. AIN-7 is hard connected to the power supply on the board. I don't know what you mean by analogRead command. The TSC_ADC_SS can sample 8 channels at 200 kHz. You can sample at that speed by using libpruio http://beagleboard.org/project/libpruio/ (bindings for C and FreeBASIC are available).

[beagleboard] How GPIO input buttons read through sys file and updating in Device tree in SDK 7(3.12)
Hi all,
I am currently using SDK 7.00 for am335x custom board, I am trying to read
the value of an input. I am using kernel 3.12 kernel. The only way I have
found is to manually export the gpio and then read the value but i want
read gpio buttons through sys. here i am using pre defined gpio drive
gpio_keys.c. find the device tree bellow...
gpio_keys_s0: gpio_keys_s0 {
pinctrl-single,pins =
0x2c (PIN_INPUT_PULLUP | MUX_MODE7)
/*key_init GPIO0_27 */
0x20 (PIN_INPUT_PULLUP | MUX_MODE7) /*
Alaram_key GPIO0_22 */
0x28 (PIN_INPUT_PULLUP | MUX_MODE7) /*
Cancel_key GPIO0_26 0x28 */
0x24 (PIN_INPUT_PULLUP | MUX_MODE7) /*
Away_key GPIO0_23 */
;
};
gpio_buttons: gpio_buttons@0 {
compatible = gpio-keys;
pinctrl-names = default;
pinctrl-0 = gpio_keys_s0;
#address-cells = 1;
#size-cells = 0;
switch@1 {
label = key_init;
debounce_interval = 50;
linux,code = 100;
gpios = gpio0 27 GPIO_ACTIVE_HIGH;
gpio-key,wakeup;
};
switch@2 {
label = Alaram_key;
linux,code = 0x102;
gpios = gpio0 22 GPIO_ACTIVE_HIGH;
};
switch@3 {
label = Cancel_key;
linux,code = 0x103;
gpios = gpio0 26 GPIO_ACTIVE_HIGH;
gpio-key,wakeup;
};
switch@4 {
label = Away_key;
linux,code = 0x108;
gpios = gpio0 23 GPIO_ACTIVE_HIGH;
};
};
I can see the the events occur in /dev/input/event0.
root@am335x-evm:/dev/input# cat event1
▒Dm8▒R
▒Dm8▒R
▒Dm8'S
▒Dm8'S
▒Dm8=
The problem is I need to read the value and not trigger off of an
interrupt. but i want read the value through sys file like leds output
root@am335x-evm:/sys/class/leds/beaglebone:green:usr3#
root@am335x-evm:/sys/class/leds/beaglebone:green:usr3# echo 1 brightness
root@am335x-evm:/sys/class/leds/beaglebone:green:usr3# cat brightness
1
please help me how to read input gpio data as well as how to export gpio
buttons attributes to sys directory
Thankas Regards

It also supports GPIO, PWM and CAP. Bindings are available for C and FreeBASIC. While most IO solutions are limited to less than 10 kHz, libpruio can work at 10 times that speed and more.

[beagleboard] Booting from microSD

I have the bone connected to a monitor, keyboard and mouse. It boots normally. I insert the microSD card press the user boot button and power it up, no light comes on at all for as long as I hold the button. If I try without the button press three lights light up immediately and stay there for ever. Am I doing something wrong? I tired connected to a network and not with the same result.

I have flashed other images on my BBB just fine before, and swear I am following the same procedure. I am: What was the full image name of the file? 1. Inserting the microSD with the image, 2. Holding down the boot switch 3. Applying power 4. Waiting for the user LEDs to all turn on then start to flash 5. Release the boot switch. The LED activity looks active for only a couple minutes then it switches to the regular heartbeat pattern, and it never goes to all 4 on again and shut down like when flashing other images even if I wait hours. Was it doing they cylon pattern? The 2015-03-01 flasher should always shutdown when done... I have found that all its doing is booting from the microSD card. If I don't power down after the flash attempt, keep the microSD installed, and check version, it indicates I'm running version 2015-03-01. If I power down, remove the card, then power back up, the old image is running. Did something change with the flashing procedure? I'm guessing there is something I have to fiddle with on the image to make this work. I'm comfortable writing code in C, C++, C#, and Java, but I'm a newbie when it comes to Linux. Any help would be much appreciated. BTW, i should mention, with this newer image. Both the hdmi serial have the flashing debug info.. So if it's flashing you should see a progress log happening on both outputs..
