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?
What kind of error do you get?
Andy
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
