[beagleboard] Disable serial consol on ttyO0
One for Robert I'm guessing, unless anyone else can help! How could I disable the serial console on ttyO0. Our hardware engineers have used this for a device I need to talk to, which I can do after the board has booted by disabling /etc/init/serial.conf however I think the board still dumps info on this port during boot, which is bad for our device and I need to power up the external device after boot to stop it going crazy... Not good. I see /boot/SOC.sh specifies serial_tty=ttyO0 and also I think I can set console= in the uEnv.txt, however playing with these stops the board booting. Is there a ncie clean way?

Re: [beagleboard] Board won't flash
So I booted off the patched SD card, cd to /opt/scripts and did a git pull. I commented out the cmdline check and ran tools/eMMC/init-eMMC-flasher-v2.sh Seemed to work fine, but the board stalls on boot from the eMMC, no error, no panic, just stops. Great. I'm guessing the scripts needs to be run from boot. Can't do that though as I get the /proc/cmdline error.

Re: [beagleboard] Board won't flash
Brilliant, I was just about to ask that. So I have my kernel build honed now, and can get our board without ethernet booting by removing the TI drivers, there are other kernel options I will play with later. So, to sort out a flasher, or use a non flasher as a flasher, even manually? (I have had no luck simply touching the trigger file...)

[beagleboard] Custom audio cape with mic - DTO?
Hi all, Bit of a strange question... We are working on something which uses a tlv320 in the same layout as the audio cape, with one difference, we have *added* an electret mic. So our board has line out left/right, line in left/right and also mic in. Apart from changing the i2c bus everything else is the same. With a modded overlay (addressing the right i2c bus) output and line input work as expected. However, the mic is not powered as no bias is being provided. Also the Alsa mixer does not mention the mic anywhere. My assumption is that I need to modify the device tree overlay to tell the driver that we have a mic present (I'm rather new to audio and dto's, so forgive me if I'm talking rubbish). Could anyone point me in the right direction to getting this mic working? Thanks in advance!

[beagleboard] Apply a patch to 3.8.13-bone47 and recompile kernel
Hi, I'm running Robert Nelson's Linux arm 3.8.13-bone47 on a beagle bone black and would like to apply a patch to /sound/soc/davinci/davinci-evm.c. I guess I need to recompile the kernel. Can someone tell me what I need to download from where and the steps I should follow to achieve this? Robert, are you out there? ;) Thanks, Tris -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

We are working on something which uses a tlv320 in the same layout as the audio cape, with one difference, we have *added* an electret mic. So our board has line out left/right, line in left/right and also mic in. Apart from changing the i2c bus everything else is the same. With a modded overlay (addressing the right i2c bus) output and line input work as expected. However, the mic is not powered as no bias is being provided. Also the Alsa mixer does not mention the mic anywhere. My assumption is that I need to modify the device tree overlay to tell the driver that we have a mic present (I'm rather new to audio and dto's, so forgive me if I'm talking rubbish). Could anyone point me in the right direction to getting this mic working? Thanks in advance!

Re: [beagleboard] Apply a patch to 3.8.13-bone47 and recompile kernel
Cheers Robert :) If I wanted to maybe mod a flasher SD card with the new kernel, and then reflash, would that be easier?

I have done the build on a linux box. Would I copy the resultant build folder to the BBB and run the /tools/installkernel.sh on the BBB? Sorry, I feel like a right idiot! There's so simple way, other then coping the built files from your pc and extracting them on the bbb while running from eMMC..

Re: [beagleboard] Apply a patch to 3.8.13-bone47 and recompile kernel
Nice one :) Yeap, and for a hint. Take the current non-flashing debian image - OK with Ubuntu too? install your kernel - by running tools/installkernel.sh on the pc with the SD card plugged in? Feel like I'm getting closer :) Thanks!

[beagleboard] Microphone Bias Voltage Level
Hi, I'm wondering how I can set the mic bias voltage level on the Audio Cape, it is currently off and I cannot get my mic to work. Can I do this via alsa or something similar?

Re: [beagleboard] Microphone Bias Voltage Level
Thank you, does that mean I need a device tree overlay that tells the
driver I'm using a mic as well as line in?
Will I need to recompile the kernel to apply this patch?

[beagleboard] Disable BB-BONELT-HDMI using uEnv
I'm rather confused. I cannot seem to disable BB-BONELT-HDMI using the uEnv capemgr.disable_partno optargs arg. My uEnv.txt line looks like this: optargs=capemgr=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN but: root@StockBBB:~#* cat /sys/devices/bone_capemgr.9/slots* 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-*L* Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI Yet I can see the uEnv was read: root@StockBBB:~# *cat /proc/cmdline * console=ttyO0,115200n8 *capemgr=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN*root=UUID=458951f9-fd96-459c-b1a3-6f2300e0fa58 ro rootfstype=ext4 rootwait fixrtc ip= Does anybody have any ideas? As a side question, the firmware for things like the BB-BONE-AUD-01 are apparently compiled into the kernel now. How could I force the dtbo to be loaded from a file? Thanks in advance for any help.
