Embedded system I/O errors

We’ve installed QNX 4.25 on a DiskOnChip on an Ampro PC/104 board.

For some reason, certain functions don’t work, even as root.

For example,issuing traceroute or “sin | grep something” returns an
“Input/Output error” (EIO?).

However, piping in general works (“find . | sin more” works fine).

There may be an obvious answer but I’m not thinking of one. Might this
be DiskOnChip related? Other functions that open/read/write/close files
seem to work fine.

Ideas?

Never mind. Some of the executables on this box were truncated to
exactly 8k in size. I hope this isn’t a common problem on these
DiskOnChips :frowning:

I would suspect DOC related. The EIO error is probably not from Pipe,
but from trying to load one of the commands of DOC.
