Hello,
Does anybody happen to know a reference with _details_ of how to format and mkfs an SD card to be bootable for freescale platform?
Background: I'm using a freescale utility ( https://github.com/kergoth/boot-format), but it fails at runtime, unhappy with my SD MBR. Console output is shown below.
I've run fdisk/mkfs with various tweaks, getting FAT16+ext2 partitions per the references I've found ( http://www.freescalewiki.com/index.php?title=Getting_started_Guide_for_P1010..., http://cache.freescale.com/files/32bit/doc/app_note/AN3659.pdf). But boot_format still bails out.
I suspect you are using a recent version but the git repo lives here:
http://git.freescale.com/git/cgit.cgi/ppc/sdk/boot-format.git/
boot_format expects the SD card will be formatted to it's expectation before writing to the SD card. You need to use fdisk and create a normal PC style partition and then format the one partition (not sure if it expects ext2/3 or fat32 for this). Play around with it and let me know.
The other option is to just ouput a spi image from boot_format and use dd to write that image to an sdcard and it should work just the same.
Let me know if you need more details.
