Hi, > [@linuxfan](#): > > ASSERT [ArmCpuDxe] /out/nvidia/bootloader/uefi/Jetson\_RELEASE/edk2/ArmPkg/Libra) It seems that the assertion error might have been truncated. Please record the entire serial console log for our review using the following command: ```bash sudo minicom -C ./serial_log.txt -D /dev/ttyACM${your port} -8 -b 115200 B ``` Thanks ---

SDK manager can not detect device via usb. The device’s usb is not shown in host pc. Do you have manual for flashing nand in device using jtag ( j-link )? Thank you for your supports. ---

Did you put the board into recovery mode before your flash attempt? If you didn’t do that then sdkm won’t detect your board for sure. ---

> [@WayneWWW](#): > > id you put the board into recovery mode before your Yes, I did. But, no usb device is found from the host. Only I can see the log attached via debug port. ( mini usb, not usb c) That’s why I can not re-flash the board. ---

if the debug port is outputted, it may not enter recovery mode. I will check if there is a problem with the recovery button. Thank you for your quick response and it helped to define the problem. ---
