is this bad or expected

[jdkullmann]

I've just gotten the serial console working and I see this on every powerup

NAND:512 MB

Checking for BootROM Routine Errors

No. of BootROM routine retries: 524288
NAND: Nand ECC error


Running diagnostics ...

It then runs DDR2 tests one of which runs for about 5 minutes before passing.

How can I shut that off?

You can turn diagnostics off by setting the run_diag boot variable to "no". The following U-Boot commands should do the trick:

Code:

setenv run_diag no
saveenv
reset
