Any idea what is wrong with my image, or what could be done to get debug informations?
The scratchpad has to fit in a special area below 1 MB. Considering various other constraints, the maximum size is probably around 512k. A bigger scratchpad will clobber interrupt vectors and wrap around to the top of the 4 GB address space. The decompressor will then write to the area occupied by ROM (writes discarded) and non-RAM areas (writes discarded). That's a bad thing.
If a compressed payload needs more than 512k scratchpad, the payload is most likely corrupt.
how can i check if the payload is corrupt or not? the uncompressed payload, the compressed one and an manually uncompressed ( lzma-utils from http://tukaani.org/lzma/) are included here: http://rapidshare.com/files/117291876/payloads.tar.bz2.html
Don't use the tukaani.org lzma-utils. They have a different header format and our decompression will choke on it.
