Hello,
according to informations that brickOS is the most powerfull of all Mindstroms
OS's, I have tried to start it. I work with a Linux 2.6 (Fedora Core 3). I
have compiled it with rcx-egcs cross compiler C and C++ cross compilers (version
1.1.2) with rcx-egcs binutils (version 2.9.5) (I could not find a newer version,
eg. 3.0, of the g++ cross compiler for hitachi).
The system was downloaded successfully to the RCX 2.0 brick with firmdl3
program. All ok up to this moment. But I COULD NOT load ANY program with the
dll utility! Each time I got an 'error deleting program' message. The green
light shows up on the USB tower, but it seems that the RCX does not respond
correctly or at all, e.g.[igor@localhost brickos-0.9.0]$ dll -p1 -v
demo/helloworld.lx
C.P. Chan & Tyler Akins - USB IR Tower Mode for Linux.

error deleting program
I tried to switch off all possible sources of infrared light, anything, but
nothing helps. It really seems that there is a problem with the USB
communication but affecting ONLY the dll utility, NOT the system download
firmdl3! If firmdl3 works, but dll does not, then it seems, that the downloaded
(with firmdl3) brickOS (the brickOS.srec file) system does not recognise the lnp
protocol?
Did any of you have similar problems? I woud really like to hear from the
system developers - you surely must know something!
all the best,
/igor
