Re: [U-Boot-Users] U-Boot-Users Digest, Vol 26, Issue 219
Hi Stuart, IF u don't have the MMU for non-contiguous memory regions,try the below steps. 1)First init all the memory banks in your board initilization code. 2)When u try to flash into 1st bank,what is the starting address of the bank?If u Starting address of ur memory is 0xE010(1MB) and when u reach the last (0xE06F)1MB in first bank just map it the memory address for the next bank address(0xE100) because u-boot will store at the last 1MB or first 1MB space of first bank for execution. 3) if image is greater than 14MB,just map the 3rd bank address after reaching the 8MB of the 2nd bank and repeat the same process for 3rd bank to map the 4th bank. Try this 2 and 3 step in u-boot flashing from MMC/SD to memory and also in reading from memory to NAND code.

[U-Boot-Users] Regarding non-contiguous support for MMC in u-boot1.3.1
Hello, I'm working for non-contiguous clusters support for MMC in u-boot 1.3.1 source code for flashing the linux images. We have a u-boot,which is working for contiguous clusters in MMC. Anybody could clarify the following my doubts in u-boot 1)Is FAT16 support is present in this u-boot? 2)If yes,how to register the MMC device to support for FAT? 3)How we could read the FAT information for getting the next cluster?
