My embedded board is freezing when I put E9171 on PCIe. What is the meaning of Unrecoverable Machine Check error about GPU?
Could PCIe settings in .dts file cause this problem? If it is, is there any sample PCIe configuration for E9171? I attached my dts file.
System is working fine when GPU is not plugged in.
This is the last console log before freeze:
