Hello,

This looks like a standard hardware recovery. We have a known bug in the GPU driver described here:

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1218318/faq-tda4vm-are-there-any-known-bugs-and-patches-that-i-should-use-in-my-gpu-driver

My suggestion would be to first ensure that it is not related to the known bug by applying the a-type patch to U-boot as described in this section:

Please let me know if you still see the GPU driver dumps when you apply this patch.

Thanks,

Erick
