Hi, we are using 7 Jetson AGX Xavier modules on our PCB, and make each module connected via PCIe & ethernet.
We are running JetPack_4.2-L4T_R32.1 with some modifications on PCIe driver and ethernet driver, and let other components untouched.
Since we cannot migrate to the latest JetPack in coming few month, so we cannot make sure whether this issue will gone in new JetPack SDK.
So we want to know how to debug this issue? Are there some internal debug methods to check ARMv8 core state?
Please give us some advices and guidance, thanks.
The previous thread as a reference:
By the way, when Linux hangs, we can interact with BPMP using jetson-demux, we can make sure that BPMP is alive and ARMv8 core has no interrupt at all.
