The problem he's describing, if it's the same one I have, is
independant of the position, direction, and power level of the tower.
It seems to have something to do with BrixCC itself. The only thing I
find puzzling is that Matt (the other Matt :-)) reports the error
happening at different stages of the download, whereas mine is
consistanly at 0008.
I ran into this problem when I was preparing for an RTL Toronto
tournament in early November. It seems to me (IIRC) that I was able to
get around it by using the serial tower early on, but later, due to my
haste, just used the USB tower and RIS2.0 for the firmware downloads.
What I'm saying here is that I didn't experiment with it enough to
determine for certain that it is a USB only problem (and only under
BrixCC).

| The size of the firmware isn't going past the 0xcc00 boundary, is it? The firmware in the RCX only does a sum on the bytes up to 0xCBFF in the downloaded firmware, as far as I recall... Cheers, Ralph (22 years ago, 13-Dec-02, to lugnet.robotics.rcx)
