PuCrunch not working as intended
Closed this issue · 4 comments
I've compiled all the tools required to make the build and when make runs:
pucrunch -f -c64 -x0x5000 build/bsw/kernal_combined.prg build/bsw/kernal_compressed.prg 2> /dev/null
it fails with the output:
make: *** [Makefile:330: build/bsw/kernal_compressed.prg] Error 1
running the command:
pucrunch -f -c64 -x0x5000 build/bsw/kernal_combined.prg build/bsw/kernal_compressed.prg 2
gives the following error:
Only two filenames wanted!
and running the command:
pucrunch -f -c64 -x0x5000 build/bsw/kernal_combined.prg build/bsw/kernal_compressed.prg
gives the following error:
Only programs from 0x0258 to 0xffff can be compressed (the input file is from 0x785c to 0x1285b)
Any ideas on how to fix it?
Thanks.
0x1285b-0x785c=45055 so the length is ok, but the offset is strange.
Please compare

@polluks Using the same command as you the output is the following:
Only programs from 0x0258 to 0xffff can be compressed (the input file is from 0x785c to 0x1285b)
@El-Virus The message from pucrunch about loadaddress 0x785c shows first two bytes of assembled file instead of loadadress 0x5000.
Check what is your shell. I had /bin/sh linked to /bin/dash (Ubuntu 18.04) and the part in Makefile that saves loadaddress failed for me. Please see this comment #11 (comment)
