I've run into this problem a couple times, and can't figure out what the problem is.
Connected to the dingoo via usb networking, or even via a serial cable, I'm in a shell session, and I try and execute a program, and it tells me the program is not found -- yet if I list it, the program is right there:
-sh: ./some-script: not found
# ls -al some-script
-rwxr-xr-x 1 root root 58 May 5 16:14 some-script
I can't figure out what makes it do this, but if it says it once, it will never execute the program. In the case of a shell script, I have to just delete it and rewrite it, or write it again with a new file name.
In the case of a compiled program, I don't know what to do - I have a bunch of programs compiled for Dingux that work under a different zImage but don't work under the normal one. I've checked the md5sum to ensure they didn't get corrupted when I moved them. Everything seems legit, but Dingux just refuses to run them...
Is there something I'm missing?
