We are working on custom carrier board for Jetson Nano module. On our custom board, sometimes 10-second timeout may occur during the detection of an embeded USB-HUB in L4T Cboot, as shown below. OK: [0002.962] xhci0: 64 bytes context size, 32-bit DMA [0003.002] usbus0: 5.0Gbps Super Speed USB v3.0…

Hi, There is a simple way to disable it in cboot. Please go to flash_l4t_t210_emmc_p3448.xml and remove below line. < filename> rp4.blob < /filename> After this step, cboot will not have xusb firmware so the initiation will not work in cboot. Please see if it can workaround your issue.
