[U-Boot] Request for Help: How to save data to an SD/MMC card

[Graeme Russ]

Hi All,

I have a need to dump memory contents to a filesystem on an SD/MMC
card so I can transfer it to my dev PC. I don't have a working network
driver, so TFTP is out

Now I notice that U-Boot has code to support writing to FAT
filesystems, but it does not appear to be plumbed in

Alternatively, I could patch up the recently posted ext4 code and give that a go

Is there any other existing mechanism to write a file to a filesystem
on an SD/MMC card in U-Boot?

Regards,

Graeme
