Is this board supported in the public U-Boot git tree?
No I think, It come with sources on CDROM, however this board looks like
Well, probably you should direct your questions to Olimex technical support, then.
Hmmm... I am a novice :-) - my first time with 32 bits and U-Boot :-) - I tought that in some way memory map on U-Boot would be the same for every boards, dependant only on the MCU.
No. The memory map is something that is board specific. Actyally you define it when you port U-Boot to a specific board.
So them I assume the information on manual are what I am looking for. Is there any way to know that looking at sources of U-Boot?
Sure. Most of these definitions are in the board config file, include/configs/<board>.h
In the manual of the dev. board I have a memory map that says the 64MB RAM starts at 0x20000000 and ends on 0x23FFFFFF - If I do "tftp 0x20000000
...
Probably because you are overwriting the exception vectors?
Hmm... So I must know detailed memory map, and that depends on U-Boot usage,
Not on usage, but on the configuration chosen by whoever ported U-Boot to that board.
Try using some offset - say 256 kB or so; that should be sufficient in any case - i. e. try 0x20040000 as download address.
Can you guide me? -- If I find the right address and use it on the -Ttext link time and on the tftp load and go command, my original program should work? is just that "simple" to have a externall application?
I really think you should ask the vendor who provides the code. Only when they get a sufficient load of support calls they will learn that it's better to push their changes back upstream.
