I am trying to boot linux with a ramdisk on a board based on TI dm6446.
I am facing a weird problem: it correctly boots images smaller than 2.5MB, while bugger ones stop boot after image decompression, before the kernel boots.
I'm not able to find out the reason why it hangs.
Do you have any suggestion?
One common pitfall is that during decompression some vital code is overwritten by the decompressed data. Double check that the memory area to which you are decompressing your image is large enough to hold the uncompressed data and doesn't overlap with any code.
Thanks for you answer Markus,
this is what I suspect, but I don't have any idea how I can check it. I mean, how can I see where the decompressed image is put? I tried giving a look at lib/inflate.c to check how gunzip() works, but I'm not able to figure out where inflated data goes....
Bye,
Ottavio.
