Hi,
if I am not wrong, I have a problem similar to Martin's:
When I load the legOS-0.2.2 kernel to the RCX,
the kernel dies leaving "on -" on the LCD.
It doesn't accept any key input,
only removing the batteries helps.
When I nevertheless try to load a user program, the
"V"-like transmission symbol appears for a
fraction of a second, then nothing...
Strangely, the same kernel with the same firmdl3
loads and runs smoothly on Markus's machine
while his doesn't on mine.
BTW, I had no problems at all with legOS-0.1.7.
Can anyone help me?
Thanks,
Heiko
