In a typical boot, we have a SD card with two partitions, one for the file system and one for for kernel image. To update a file system, we placed the SD card in a reader and copied the new file system over. I would like to be able to tftp a file system image over. As I understand it, the tftp can be done from the 2nd stage u-Boot. However, it can only dump the image into the fat32 partition. I would like to mount the file system directly from the fat32 partition. Has anyone tried do this? Yes, I realize I can make a RAM Disk. However, I would like to avoid the boot time penalty of having to push the file system image into main memory.
