yosemite flash confusion

yosemite flash confusion

[Peter Fercher]

hi,
the yosemite (revision 1.1) i got has a 512 MBit Flash chip on it
(S29GL512).
u-boot 1.1.3 that came with it was configured to use only 32 Mbytes ???

trying to use the whole size of the flashchip on the board I run into the
following problem:
when i try to use the u-boot.bin (newest from the denx homepage:
ftp://ftp.denx.de/pub/u-boot/images/amcc/yosemite/) then i get:
(reprogrammed using the yosemite.cfg that was mailed to this list some days
ago)
U-Boot 1.1.4 (Oct 24 2005 - 09:23:33)

AMCC PowerPC 440EP Rev. B
Board: Yosemite - AMCC PPC440EP Evaluation Board
        VCO: 1066 MHz
        CPU: 533 MHz
        PLB: 133 MHz
        OPB: 66 MHz
        EPB: 66 MHz
        PCI: 66 MHz
I2C:   ready
DRAM:  256 MB
FLASH: 64 MB
*** Warning - bad CRC, using default environment

PCI:   Bus Dev VenId DevId Class Int
In:    serial
Out:   serial
Err:   serial
Net:   No ethernet found.

Type "run flash_nfs" to mount root filesystem over NFS

Hit any key to stop autoboot:  0

it sees the 64MB flash but somehow can't find the ethernet anymore..
does anybody know what the problem is there ?

cheers, peter

Dear Peter,

Seems they installed an old version of U-Boot.

This means you did not set up your environment and used "saveenv"  to
store it. This also means that your MAC address is undefined.

You forgot to set the MAC address...

Please set the "ethaddr" environment variable to define a  valid  MAC
address,  then  use "saveenv" to save it to flash, and then reset the
board...


BTW:  this  is  off  topic  here.  You  should  have  posted  on  the
U-Boot-Users mailing list instead.

Best regards,

Wolfgang Denk
