Other Parts Discussed in Thread: TDA4VH-Q1
Tool/software:
Hello everyone,
We are currently working with SDK 10.0 on a custom board based on the J784S4 and are encountering Linux kernel panics under heavy RAM and CPU usage. This issue was initially reported by our customer while developing applications on the board, and we have been able to reproduce it using the stress-ng --vm 5 --vm-bytes 2G --timeout 10m tool. Based on our observations, we suspect that the issue may be related to RAM misconfiguration.
As part of our modifications, we removed two instances and reduced the total RAM from 32 GB to 16 GB. I will provide a patch detailing all the changes we made.
Additionally, we ran the memtester application as part of our diagnostics, but it did not report any errors.
Could you provide guidance on how to further investigate and resolve this issue? Any insights would be greatly appreciated.
Best regards,
Dušan Stanišić
