Hello, nVidia Support,
We have a set of PCIe driver for our device, which works well in kernel 4.9 and JetPack 32.5; the driver works in user mode.
After we flashed the system to SDK 5.0.2(kernel 5.10), and after re-compiling the driver, the driver no longer runs, and during DMA stage, it reports this error:
