Problem flashing TX2-NX modules

I have been able to flash/program a lot of TX2-NX from recovery mode for a long time.
But now i have problems after getting a new batch of TX2-NX modules.
My sudo ./doFlash.sh script now starts hang on “Can not open USB”:

i have tried on several modules in same batch and have same issue.

Have any body had same behavior and found the reason/solution?

Keyword here is “new batch”. What Jetpack version is in use?

Most likely due to PCN update.

thank for the input - I will try to see if the FAB or SKU are updated for the new modules.

Now I have this debug info:

flashing old batch module ( PASS) : BOARDID=3636 BOARDSKU=0001 BOARDREV=H.0 BOARDSN=1421224255416 Fuselevel=fuselevel_production

flashing new batch module ( FAIL) : BOARDID=3636 BOARDSKU=0001 BOARDREV=C.0 BOARDSN=1424724347769 Fuselevel=fuselevel_production

My yocto build are based on kirkstone-l4t-r32.7.x (l4t r32.7.3 - jetpack 4.6.3)

By searching i see a possible solution here by upgrading to 32.7.4:

I will let you know when tested l4t r32.7.6 - jetpack 4.6.6 (final eol version for TX2 support)

Great news.
By using l4t r32.7.6 - jetpack 4.6.6 my flash/programming problem is solved.
It works on both old and new batch of the my TX2 NX modules :)
