Dear NVIDIA,
We are testing jetson agx xavier 8GB module with custom carrier board and we have used XR17V352 Pcie to Uart IC for PCIe to uart conversion and XR17V352 is connected to C3 controller of jetson agx xavier. when we try to transfer data from other system to jetson through UART(Jetson to other system communication is ok), system is crashing and below is the log file from debug port. Please check and provide the solution.
