Part Number: AM3354
Other Parts Discussed in Thread: AM3358,
Hi,
Our customized board is based on Beaglebone Black. Due to parts shortage, we had to use both AM3358 and AM3354.
We encountered an issue that Linux crashes when starting up, and it happens only on AM3354, not on AM3358.
TI has previously confirmed there is no software change needed to use AM3354 and AM3358 interchangeably.
So here are my questions:
1. Is this a known issue that has been fixed? If yes, which commits from the dunfell branches contain the fix?
2. Or anything needs to be modified (in device tree?) for the Linux kernel to be able to boot from both AM3354 and AM3358?
Please help. Thank you!
Here are the TI kernel information:
TI kernel ti-linux-5.10.y branch, tag: cicd.2022.10.28.09.04.44.
Kernel is built using Yocto build system:
poky branch dunfell 4ddc26f4e4c7 (~10/17/2022)
meta-ti branch dunfell 4d6de396af24 (~11/04/2022)
I also attached the kernel start up log here.
