Hi,
I’m trying to bring-up a new Jetson Xavier NX carrier. We have a carrier that we’ve been using for a couple of years, this new carrier is just the same but in a different form factor.
There are some small differences between the design of the old and new carrier which I could explain if anyone thinks it is relevant.
Because we believe that this new carrier is the same as the old carrier I’ve tried to flash the NX using the same procedure. I have an old and new carrier on my desk. I can flash the NX on the old carrier. I then connect the USB to the new carrier but when I repeat the commands, ./flash.sh fails.
The error message that I see is:
[ 10.8854 ] Sending bct_mem
[ 10.9354 ] [................................................] 100%
[ 10.9413 ] 0000000000000102: E> NONE: Invalid value MemBct dram size: 0MB for slot: 2.
[ 10.9578 ]
Is there anything I can try to debug what’s going on?
At the moment I don’t know if this could be a problem with the new carrier or if I need to do something different in the flashing procedure.
The Jetson Xavier NX modules have the same part number, 900-83668-0030-000. I haven’t tried moving a module between carriers because it is quite hard to disassemble the old carrier and remove the heat sinks.
Below is a longer extract of the output I see, I can provide more if anyone thinks it will help.
Any thoughts greatly appreciated,
Matt
