Hi @all,

one minor Problem I often read about in this list is some crappy / unreadable
console output at beginning of the U-Boot start procedure. Now I have the same
"visual" Problem.

| H?NAND:  128 MiB
| *** Warning - bad CRC, using default environment
| 
| In:    serial
| Out:   serial
| Err:   serial
| Net:   macb0
| macb0: Starting autonegotiation...
| macb0: Autonegotiation timed out (status=0x7849)
| macb0: link down (status: 0x7849)
| Hit any key to stop autoboot:  0 
| ...

Sometimes I get a good readable output, which looks like so:

| U-Boot 2012.04.01-00003-gab465ef-dirty (Jul 23 2012 - 14:44:29)
| 
| U-Boot code: 23F00000 -> 23F30464  BSS: -> 23F72128
| CPU: AT91SAM9G20
| Crystal frequency:   18.432 MHz
| CPU clock        :  396.288 MHz
| Master clock     :  132.096 MHz
| RAM Configuration:
| Bank #0: 20000000 64 MiB
| WARNING: Caches not enabled
| NAND:  128 MiB
| ...

Has anyone an ideea how to fix this? Or what's the cause of it? Is it even
related to u-boot or is it something at91bootstrap is doing wrong?

Cheers, Markus
