The K1 has a PXA255 processor (armv5 compatible). I found a toolchain that is supposed to support it:
ftp://ftp.gwdg.de/pub/linux/misc/lin...1-26-04.tar.gz
Hopefully I can (re)compile stuff (including tcc and gmplay and other apps) to support it. Though if tcc RUNS on it, I suppose that code compiled with tcc may still have compatibility issues...
But still, from what I have read so far, compiling anything with softfp OUGHT to work (though it clearly does not)...
EDIT2: I tried both toolchains recommended for the PXA255 linux kernel project (for kernels 2.4 and 2.6), and in both cases, executing a "hello world" app compiled with them (both with and without "-static") gives and "Illegal instruction" error. I guess the next step is to try this:
