I’ve also captured USB traffic via usbmon and Wireshark. With enough replug attempts I can get the flashing to work. I’ve also tested against the standard Jetson TX2 Developer Kit with the JetPack 3.3 flashing utilities with similar results. In the above log you can see the prompt that I added requesting an unplug and replug - at this point I physically unplug the USB cable to my device and then plug it back in and the tegrarcm_v2 command will succeed after one or more replug attempts. tegrasign_v2 -key None -getmode mode.txt Unplug and replug USB cable then press ENTER. tegrarcm_v2 -chip 0x18 -rcm rcm_list_signed.xml tegrarcm_v2 -chip 0x18 -updatesig rcm_list_signed.xml tegrasign_v2 -key None -list rcm_list.xml -pubkeyhash pub_key.key List of rcm files are saved in rcm_list.xml tegrarcm_v2 -listrcm rcm_list.xml -chip 0x18 -download rcm mb1_recovery_prod.bin 0 0
Type ? or help for help and q or quit to exit The output of my session is as follows: Welcome to Tegra Flash I modified tegraflash_internal.py to prompt me to unplug and replug my USB cabled when it detects an error response of ‘BootRom is not running’ which helps to overcome this issue. I’m developing on Ubuntu 16.04 on a Dell XPS 15 9570. I’m using tegraflash.py to flash partitions on a custom TX2 device but I’m experiencing hangs most of the time when I attempt this operation.
