Invalid value MemBct dram size: 0 MB” Error When Flashing 8 GB Jetson Xavier NX on JetPack 4.6 (L4T 32.6.1)

Hi all,

We’re trying to flash several 8 GB Jetson Xavier NX modules (part number P3668-0000, production date Q4-2024, Micron DRAM) with JetPack 4.6 / L4T 32.6.1 .

Every attempt stops at the BCT stage with the message:

[   5.5341 ] 0000000000000102: E> NONE: Invalid value MemBct dram size: 0MB for slot: 0.
Error: Return value 2
Failed flashing t186ref.

Is there an updated MB1/BCT package for JetPack 4.6 that supports this Micron DRAM revision on 8 GB NX modules?
or
Has anyone succeeded in flashing these newer 8 GB boards on JP 4.6, and if so, what exact patch or overlay did you use?

Please check PCN center

If there is no PCN overlay for the version you need, please upgrade the BSP.

I couldn’t find a suitable overlay for my Jetpack 4.6 XavierNX device at the PCN Center. However, I can’t update the BSP either because all my programs are compatible with JP4.6. Is there another solution?

Nope. No other solution.
