would you be able to come up with a short list of "fixes" that have been done?the notable problem fixed in OMAP4 vs OMAP3 boot code is related to how the ROM code will read the FAT table. in OMAP3 if you keep replacing the MLO/uboot/uimage (whether you cp or mv to it) after a while (~10 iterations, iirc) the ROM code will not be able to locate MLO anymore, and you need to reformat the card. this problem is fixed on OMAP4. there might be other things, but this one was really the biggest issue i think.
thanks!
also, note that the SD can be used as RAW instead of FAT, in which case you aren't going through the embedded FAT implementation and avoid such issues.
sure, that's how we boot from emmc :)
