Hello,
I hope I am not sending mail to the wrong mail list.
I am porting u-boot to our Xscale based board, with 32MB Nor Flash on board. And in this board, it is required that, the u-boot should be able to read some files from a FAT file system on one of the Nor Flash partitions. The Nor Flash is managed as MTD device under Linux OS.
In current u-boot implementation, I can use fatload to read files from mmc or USB storage device, which is also FAT filesystem. And I can also use fsload command to read files from JFFS2 filesytem on NorFlash or NandFlash.
But I found I cann't uses these command to read files from a FAT filesystem on NorFlash. I cann't format this partition to JFFS2 filesystem because it is exported to Windows/Linux host via USB gadget after system boots up.
Can someone tell me the best way to solve this problem, or give me some hints of which part of code I need to change?
I am creating a new command following fsload, using MTD devices in U-Boot, and try to mount the FAT filesystem, but failed at reading the real file data out, although I can read the file name, the file size and the file start sector number out.
