Hello NVIDIA engineers:
I have a pcie question.
We are using an external RM500U 5G module mounted on the pcie above nano/nx, but the pcie bus keeps reporting an error when in use:
[ 100.375000] tegra-mc 2c00000.memory-controller: pcie9ar: secure read @0x000000ffffffff00: EMEM address decode error (EMEM decode error)
[ 100.375008] tegra-mc 2c00000.memory-controller: pcie9aw: secure write @0x00000003ffffff00: VPR violation ((null))
[ 100.375014] tegra-mc 2c00000.memory-controller: pcie9aw: secure write @0x00000003ffffff00: Route Sanity error ((null)) pcieMsi_dmesg.txt (103.0 KB)
Test environment:
Jetpack 6.2 , custom boards and devkit can reproduce the problem.
I refer to the patches inside these two links, but the problem does not improve.
Note: The same hardware environment is fine on jetpack 5.1.3. I suspect the problem may be with the nvidia pcie driver, but it’s too different from 5.1.3.
