I am new to Mindstorms, but not new to computer science. Anyway I am unable
to load any program to the RCX robot using the dll. I have built the brickOS
system using a egcs (v. 1.1.2) hitachi cross compiler on a Linux platform
running the 2.6 kernel, Fedora 3 edition. I managed to dowload the brickOS
system, therefore the USB IR tower I am using seems to operate correctly.
But any time I wanted to download a program, it ended up in an 'error
downloading program' message! A typical output is like
[igor@localhost demo]$ dll -p1 -v helloworld.lx
C.P. Chan & Tyler Akins - USB IR Tower Mode for Linux.

error deleting program
What is the matter? The IR connected and the RCXTTY environment variable set to the /etc/udev/usb/legotower0 device file (the green lamp in the tower lights up), the RCX is switched on, there seems to be a connection (different bytes are returned on subsequent tries), the brickOS was transferred successfully with firmdl3.
What is the real problem? Is there is something wrong with the dll program?
Answer please if you know anything.
