How much is "very limited" ?
If you want to use that board for any reasonable pourposes, which justify the use of a boot loader like U-Boot, then you probably have more than enough RAM to run U-Boot.
FLASH rather than RAM. Has anyone else done this? I played with this a couple of days with out much success. Is it do-able, without too much effort?
It would be significant effort. And it makes not much sense, as you would lose a lot of basic functionality, resp. have to work around the resulting restrictions.
It doesn't make sense to me. Rather think how to make it fit into avilable RAM. How much RAM do you have?
Best regards,
Wolfgang Denk
