[U-Boot-Users] MMC 4GB with at91sam9260 ...

[Pierre Savary]

Hi,
I need some help because I want to use an eMMC of 4GB but my U-Boot (1.1.5)
see it but can't use it... So I think it is a problem with "Max read data
block length" but I don't know what I can change in the code ...
Have somebody already try this?
Could you help me please?

Thanks in advance,
Regards,

Pierre

I can't read on the MMC. When I make "mmcinit" :
Manufacturer ID:       15
OEM/Application ID:    0000
Product name:          000000
Product Revision:      1.11
Product Serial Number: 2701132109
Manufacturing Date:    00/10
CSD data: 9026012a 0f5903d3 f6dbffe9 96404093
Supports partial reads
Does not support partial writes
Card capacity:          556032 bytes
Write protection:
max_blksz = 1

and when I make "ext2load" :
....Failed to mount ext2 filesystem...
** Bad ext2 partition or disk - mmc 0:1 ** 

Thanks for your help,
Regards

Pierre
