Wolfgang,
i followed your advice :
Well, did you check "examples/Makefile" ? Right at the beginning it reads:
ifeq ($(ARCH),arm) LOAD_ADDR = 0xc100000 endif
And replaced the load address to point to 0x20000000, which is the start of RAM banks on the 9200EK. After tftp loading at 20000000 the hello world application worked fine. I also tried to boot directly (btw of u-boot) this application, previously stored in flash, by changing the "start" env variable, and it also worked fine.
I could not load u-boot 1.1.6 in my board, but it seems to be not compliant with it (i ve read some posts about patches that must be applied but i don t know how). However, loading u-boot 1.1.6 is not mandatory to be done for me, i just wanted to start booting custom code (in few words, we are trying to port a component-based OS to that platform).
So, thank you very much for your help !
PS : i just wonder if it should be possible to duplicate the 9200DK board conf and override the load_address for examples, it is just an idea but i am not very sure the include order of makefiles allows that.
Baz.
