Hi Steven,

I need a boot loader for an ARM7tdmi (NetSilicon 7520 based UNC20 board = from Forth Systems) has anyone seen such an animal? U-Boot seems to only = work for the ARM720, is this true?

Sorry, no experience with NetSilicon stuff, but.. U-Boot runs very well on plain ARM7TDMI core, take a look at board/dave/B2 (which is based on Samsung S3C44B0X) and cpu/s3c44b0x (which is an ARM7TDMI processor). Sorry but there is not a cpu/arm7tdmi directory ;-). Still I never try to compile in Thumb mode, but only using ARM instructions.

Best Regards,

Andrea Scian
