Hi, Sir,

 

I have a BF518f-ezbrd, and download u-boot-bf518f-ezbrd-spi-2009R1-rc2.ldr from the website,  it works. When I insert the 256M SD card into the Ezbrd, type "mmcinit", it displays as following:

 

bfin> mmcinit

CID information:

Manufacturer ID:       03

OEM/Application ID:    5344

Product name:          SD256

Product Revision:      8.0

Product Serial Number: 1359397149

Manufacturing Date:    03/14

SD Card detected (RCA 58916)

CSD information:

CSD structure version:   1.0

Card command classes:    5f5

Max trans speed: 25MHz

Read block length:       512

Write block length:      16

Card capacity:          252968960 bytes

 

then I type "fatinfo" command, it diaplays:

 

bfin> fatinfo mmc

 

** Invalid boot device, use `dev[:part]' **

bfin> fatinfo mmc 0:1

 

** Unable to use mmc 0:1 for fatinfo **

 

I don't why.  Does u-boot-bf518f-ezbrd-spi-2009R1-rc2.ldr support MMC and SD Card?

 

Thank you.

 

Weeklly.

mmc should work fine.  if you're getting errors, check your syntax and make sure the card is correctly formatted.

Yes, the 256M SD Card has been formatted by PC(windows XP), it's fine.

I mean the SD Card is fine,but it doesn't wotk well in Bf518f-ezbrd, I doubt that the u-boot-bf518f-ezbrd-spi-2009R1-rc2.ldr supports MMC and SD Card.

I saw a similar problem, but after I formatted the card in Linux - the problem disappeared, and I could never make it happen again.
