PW2 Variable for Board ID

filonstr · 12-13-2022, 03:55 AM

The PW2 book was scribbled a long time ago, literally in the 3rd month of life. That time came and decided to restore. I connected the serial port, Putty showed that there was no Board ID and S / N, because the error

Code:

Board: Unknown
Boot Reason: [ POR ]
Boot Device: NAND
Board Id:
S/N:
I2C:   ready
Invalid board id!  Can't determine system type for RAM init.. bailing!
DRAM:   0 kB

As a result, it does not go to bist.
The command (I took the serial from the bulldozer) turned out to fill in S / N.

Code:

idme serial B0D8070834561316

But how to fill in the Board ID (what variable)?

The variable you're looking for is pcbsn, IIRC.
