'INIT: Id "AMA0" respawning too fast: disabled for 5 minutes Beaglebone Black Yocto
I'm having trouble getting a Linux distribution to run on my board. I compiled a new project following the instructions on the yocto website(https://docs.yoctoproject.org/brief-yoctoprojectqs/index.html). I cloned code from Poky repository by tag name yocto-3.1. I'm also add changes to the local.conf file. The compilation was successful but when I upload the code to the SD card and turn on the board I can see the logs but the system locked in the AMA0 initialization. I tested compiling Linux in QEMU and it works. I don't have any idea to solve this problem.
I'm added logs from compilation:
WARNING: Host distribution "ubuntu-20.04" has not been validated with this version of the build system; you may possibly experience unexpected failures. It is recommended that you use a tested distribution.
