Hi all, when I reboot I see this:


CPU:   ADSP BF537 Rev.: 0.2

Board: Bluetechnix CM-BF537 board

       Support: http://www.bluetechnix.at/

Clock: VCO: 500 MHz, Core: 500 MHz, System: 100 MHz


Device ID of the Flash is 890016

Flash Memory Start 0x20000000

Memory Map for the Flash

0x20000000 - 0x201FFFFF Single Flash Chip (2MB)

Please type command flinfo for information on Sectors

FLASH:   2 MB                ****

In:    serial

Out:   serial

Err:   serial

Net:    ADI BF537 EMAC

Hit any key to stop autoboot:  0


But the Bluetechnix CM-BF537 board has 4MB on flash, not 2MB. Why is it?, How to change it?



When I see the flash information:


CM-BF537> flinfo


Bank # 1: MT_MANUFACT_on_CM-BF533

    20000000 (RO) 20020000      20040000      20060000      20080000   

    200A0000      200C0000      200E0000      20100000      20120000   

    20140000      20160000      20180000      201A0000      201C0000   



Why CM-BF533 now?, Could it be the problem? How can I change it to CM-BF537?

you didnt say what version of u-boot you're working with


as for the flinfo output, that is simply what is hardcoded in the custom flash driver

The version is: U-Boot-1.1.3-ADI-2006R1 (May 12 2006 - 11:22:12)



I am afraid of upgrading due to it worked well before with the NFS, is it necessary?

i dont understand ... u-boot doesnt know/understand/care about NFS in any way


the tinyboard has 4 megs, but only 2 are mapped at a time.  if you want to flip to the other flash, just use the pf4 command.
