I build an embedded linux with YOCTO for the KARO TX6S-8035 target. I
use the fsl yocto project
<https://www.karo-electronics.com/1646.html?&L=1> given by KARO.
I use the Mfgtools-TX6-2018-01 tool to flash images into the board but
when i boot the device i have the following error:
*Kernel panic - not syncing: Requested init /linuxrc failed (error -2)*.
How can i fix this?
Here is the result of printenv from U-BOOT: printenv
<https://pastebin.com/7jvaM0wV>
This shows the Karo u-boot is configured to start /linuxrc:
(...)
default_bootargs=setenv bootargs init=/linuxrc console=ttymxc0,115200 ro
debug panic=1 ${append_bootargs}
(...)
Solution 1 is to create a file fixboot.env in the
/mfgtool/Profiles/TX6/custom directory containing a single line:
default_bootargs=setenv bootargs init=/<real_name_of_init>
console=ttymxc0,115200 ro debug panic=1 ${append_bootargs}
with <real_name_of_init> replaced by your actual init (e.g. /sbin/init).
In the Mfgtools setup MfgToolSetup.bat you need to select this .env file
when asked for additional environment settings that are found in the
custom folder.
Solution 2 is to create a small executable script called /linuxrc in
your rootfs with the following contents:
#!/bin/sh
echo "Executing /sbin/init $@"
exec /sbin/init "$@"
This worked fine when I worked with Karo modules using a Ubuntu rootfs.
Obviously, this assumes that /sbin/init is your real init.
Cheers,
Bas.
