Upgrading Kernel on BeagleBone Black

My guess is the environment or directories was not built. Please capture  /etc/rc.local/ here.

Please, find below the content of '/etc/rc.local':

     #!/bin/sh -e

     #

     # rc.local

     #

     # This script is executed at the end of each multiuser runlevel.

     # Make sure that the script will "exit 0" on success or any other

     # value on error.

     #

     # In order to enable or disable this script just change the execution

     # bits.

     #

     # By default this script does nothing.

     echo ttyO2_armhf.com > /sys/devices/bone_capemgr1/slots

     echo ttyO5_armhf.com > /sys/devices/bone_capemgr2/slots

     exit 0

Just comment out two echo lines since by default it does nothing.

Hi,

I have just commented both lines, and the process goes well until console starts to show:

"INIT: Id "T0" respawning too fast: disabled for 5 minutes"

Then, the process enters into an infinite loop showing message every 5 minutes.

What process is T0? And how can I solved this?

KR!

The "respawning too fast" message is telling you that your X-server (or xorg.conf file) is miss-configured, and the X-server is crashing when it tries to start and trying to restart too fast or too often.

From the command line, look at /var/log/Xorg.0.log to see why the X-server crashed, and fix the problem.

I believe you need to recheck the tutorial or restart the build? This is not a small issue.

Hi,

is is fixed.

Finally, I have changed the BBB's kernel (3.8.13 -> 4.1.16).

I had to modify one line into '/etc/inittab' file.

• Original: T0:23:respawn:/sbin/getty -L ttyO0 115200 vt102
• Modified: T0:23:respawn:/sbin/getty -L ttyS0 115200 vt102

Then, after doing the whole process I have written my own tutorial with the steps that worked for me.

KR!

Glad you found the bad line, Do you know why the change?

Please mark helpful comments that helped you Thanks

What I have found about is:

    By default, the console definition is based on ttySx, nor as for BeagleBone where it has been changed to ttyOx.

    Then, when changing the kernel, default values are loaded again.

    There must be take into account we are compiling a linux kernel, specific for BeagleBone, but a linux kernel in its core.

That is what I have understood.

Please, correct me if I am wrong.

Curious why the beaglebone guys changed that, but good to know. Thanks
