During the startup process of my chip, I received a prompt indicating this issue. After executing for 6 seconds, it got stuck on the bpmp log and stopped starting the system.
I have two questions: (1) Under what circumstances will it be triggered, and what are the triggering conditions? Could you provide some source code interpretation?
FATAL ERROR [FILE=platform/drivers/emc/lib/t264/dvfs_training_sequence.c, ERR_UID=9999113]: fatal error: 0x0000000
(2) Is it related to bpmp? Currently, we have reproduced the issue on two devices, and the output logs are stuck at bpmp logs compared to normal:

What error codes represent?
Is the source code for dvfs_training_sequence.c open source?
[mos][11-22 15:47:31]FATAL ERROR [FILE=platform/drivers/emc/lib/t264/dvfs_training_sequence.c, ERR_UID=9999113]: fatal error: 0x00000008
It is a known issue to us and we are still debugging for the fix.
jetpack 7.1 版本能否修复？
这个问题和bpmp 有关系吗？
请问这个是否是thor单体间差异造成的？
no, this issue is from bpmp firmware.
再请问nvidia 的复现方法也是开关机压测吗？我们用不同设备做了大量的开关机测试，都没有复现问题。只是在两台机器人整机上做开关机测试偶现了这个问题。
Is this question the same as the one below, and will it be resolved in JP7.1?
One device always happen this issue when booting, and it cannot boot normally,
How to resolve this issue one this device? It is serious problem.
If only on this device, then suggest to contact our local distributor to do RMA.
