Problem with multiflashing Jetson TX2

With README_Massflash.txt , I created an archive mfi_jetson-tx2.
Flash two jetson TX2, it’s ok. When flashing three boards, one of them disconnected.

The aborted log is following:

*** Boot Rom communication

hello hotspear89,

please refer to Topic 158896 for the fixes of multi-flash.
thanks

Thanks, it’s work.
Another question. I’m use custom kernel (-K ) and orbity [CTI-L4T-TX2-32.3.1-V003) at ./flash.sh. How can i use them when massflashing?

hello hotspear89,

I’m not sure what’s your image type of orbity (CTI-L4T-TX2-32.3.1-V003)
please note that, flash script using the binaries under $OUT/Linux_for_Tegra/kernel/* to flash the board.
you may replace your customize images for flashing.
thanks

Theoretically, I can replace jetson-tx2.conf in orbity.conf. Will it work?
