I've put the app up here:
http://www.nominous.com/empeg-wideband if someone could please verify that it's working ok ?
It's the complied version of the Innovate wideband reader/display source which was posted quite a while ago.
I think you've used the wrong compiler. That file appears to be EABI (ABIv5) (judging from arm-linux-readelf -e), whereas the car-player is "old ABI".
You're getting a "exec failed" sort of error because it requires the EABI dynamic loader (/lib/ld-linux.so.
3), which isn't present; an old-ABI program uses the old-ABI dynamic loader (/lib/ld-linux.so.
2).
Where did you get your ARM compiler?
Mark Lord's page has binaries of a suitable cross-compiler from x86 Linux (search for "armtools-empeg").
