Help with mass flash on Xavier

I’m trying to do mass flashing for Xavier AGX with SDK 4.4.1. I’m getting this error when running ./ script:
*** Boot Rom communication
/home/alexi_med/mfi_jetson-xavier/tegrarcm_v2 --instance 1-4 --chip 0x19 0 --rcm rcm_list_signed.xml
BootRom is not running
*** Boot Rom communication succeeded.

*** Checking applet
/home/alexi_med/mfi_jetson-xavier/tegrarcm_v2 --instance 1-4 --isapplet
USB communication failed.Check if device is in recovery
*** Error: Checking applet failed.

How do I enter the RCM mode? Is it holding middle button on dev kit and pressing reset. This works with normal flash script but does not seem to work for mass flash. Please advise.

hello abelakurski,

please check developer guide, To determine whether the developer kit is in Force Recovery mode.

are you able to have another way to enter forced-recovery mode?
for example,

  1. disconnected power-supply,
  2. connect power-supply, and hold recovery button,
  3. press power button to power-on the devkit.
  4. release recovery button.
