When you say it doesn't work, what happens? Do you hear
the long low buzz sound that Dick Swan mentions? Or, does
the RCX just crash?
I'm not very familiar with ELF files, but I did look up the
format. Are you certain your program is all code? If you're
writing a C program, then the "Do you knock..." string will
be in the data segment. Plus any compiler generated
data, like jump tables for a switch() statement, will go into
a seperate segment. Each of these segments appears to have
a header in ELF, so these headers may be interfering
with the contiguous memory layout of your program. The
various segment headers will cause the data to appear at a
different address than expected by the program.
So, in other words, are you sure you can just strip off the
ELF header? Perhaps you could properly parse the ELF
file format and load the file into local memory before
downloading.
Hope that helps,
Mark
