What I'm doing is to prepare the debuggng kenel and crunch with debugging symbols (which of course are waaaay to big for any floppy except for LS120), and then just start the machine with this kernel and MFS image loaded from hard disk (see the standard boot floppy for the right incantations). Then I mount my hard disk filesystem and if I get a coredump, I simply copy it to that FS for analysis. You can even start gdb if you set your paths correctly. > - If I suspected that the crunch process was incompatible with some > program, how would I go about getting a non-crunched version on there? > When I grabbed the binary straight off my desktop and ran it on Pico, > it complained about ld_elf.so not existing.
