Blackfin 533 stamp board. How to boot kernel with uboot, i.e. from the images, like "linux"or "linux.initramfs", how to convert them into "ldr" file, which can be burn into flash memory. After power on, the system will be on automatically. Does "bfin-elf-ldr" be used for the convertion? If yes, does "bfin-elf-ldr -T bf533 -c image.ldr linux" OK for the convertion? Thanks a lot.

In theory - yes that should work - although no one has tried is since ldr formats do not support compression natively, and most people want the flash image gzipped to save some space.

it'll work in the sense you'll get a valid ldr, but it wont work in the sense that it'll actually work

 

the kernel does not handle programming of clocks in an init block and it probably wont for a while since this is a very low priority item (due to some of the reasons Robin has listed)
