Hi Everyone,

I have an SD Card which has 2 FAT partitions. U-boot is in the first Boot partition and i have a text file to be read which is in another partition.

I want to read this file in the U-boot config file under CONFIG_BOOTCOMMAND. can anyone please let me know what commands U-boot introduced to support file read in the latest release?

Thanks. Harsha

OK - and what exactly is your problem? If you tried something and it failed, it would be helpful if you posted your attempts (and the resulting errors) here...

None. Reading files from FAT partition has been available for ages.

Hi ! I am sorry i should have been more specific. I am now able to load the file from a different partition and see in the memory.

I do not see any commands in u-boot help to create a New file/ delete a file / Rename a file. Is there any support for these file operations from u-boot?

Thanks, Harsha

No, there isn't. U-Boot is a boot loader, not a full blown OS.
