Hi,
I have been trying to use my lego mindstorms kit along with the USB IR
Tower in linux. I have had limited success. I managed to patch the
distribution so that firmdl3 recognizes the usb device. I compiled a
module for the USB tower device. It shows up in "/dev/usb/lego0" and I
made a link at "/dev/legotower0".
Here is the output of firmdl3 when I try to download the brickOS kernel.
/usr/local/bin/firmdl3 -u --tty=usb -d -v brickOS.srec
using priority scheduling
attempting to init in fast mode
mode = fast
testing if tower is alive in fast mode...sendrecv 1:
attempting to set timeout to 50
recvlen = 7
R 0000: 55 ff 00 ef 10 ef 10
status = no error

/usr/local/bin/firmdl3: delete firmware failed
Here is some info about my system:
GCC: 3.2.2
binutils: 2.13.90.0.18
linux-flavor: gentoo
kernel-version: 2.4.20
brickOS version: CVS
I am trying to use the patch found on the sourceforge site, dated
2002-09-11. The Request ID is 608191, and it was submitted by cfriesen
Has there been any progress made on the linux usb situation?
The firmware is hosed after I attempt the download. Lego application
needs to restore it the next time that I attempt to download a program.
Has this problem been seen before?
Thanks,
Dan
