I would like to code standalone app under uboot that would test my eth chip. I tried running hello_world.srec from ram location and I got 'prefetch abort' on go. My procedure follows: tftp a0100000 hello_world.srec go a0140004 test test2 (go a0100000 test test2)
How comes you are using 0xa0100000 as load address? Did you modify the Makefile so that this address gets used? The default value used in U-Boot for ARM systems is 0xc100000 ...
I'm trying to download hello_world.srec to the memory and run it from the memory, as i do with the kernel. I didn't change any Makefiles nor any of the sources. Was it wrong to think that I could execute an image from the memory that way ?
address value for go is memory location plus offset defined in Makefile. Both go commands yield an error and reset the board.
Try running the code under a debugger...
Yet to learn :). Going slow though.
