In that particular order? The boot partition has to be first and should have a bootable flag enabled. If your boot.bin is correct you should at least see a message from FSBL. I suggest you byteclone your reference card to yours (if your is the same size or bigger) to start with the correct partition table in the first place. You can then wipe out contents before trying with yours from the build. Actually, the only REAL requirement is that the first partition is FAT (16 or 32, doesn't matter) because that is what the ROM needs. It need not be marked bootable at all. This partition only needs to hold boot.bin (and u-boot.img if you use SPL) so it could be only a few megabytes in size. U-boot (after the ROM started it) will locate the bootable partition and look for a boot script named "/boot/boot.scr". If found, it executes whatever is in there. You can mark the ext4 partition as bootable for example, provided that you put the bootscript (and kernel and devicetree which it will probably want to load) in it. This allows you to have multiple partitions on the SD card (or eMMC). That in turn allows you to update a partition that you aren't using, and then mark it bootable, thus performing a "live" upgrade. No more walking around with SD cards! Xilinx' default strategy is to have no partition marked bootable at all, which causes u-boot to hunt for the bootscript on the first partition. Also works. ... -- Mike Looijmans System Expert TOPIC Embedded Products B.V.
