We had been building a handyboard(hb) but we have severe problems,
We download the buffalo using the hbdl windows downloader (dl indicates a
serial timeout, dlm just hangs up).
When Buffalo is succesfully loaded (it sometimes halts with a error in
address 0x0000)and a power cycle is made the memory is lost. If we connect
pin 17 of the HC11 (reset) to GND instead of a power cycle the system resets
and the buffalo prompt is displayed. Buffalo seems to be working as the help
and load commands work properly.I tried making a block fill to the motor
outputs. The command is carried out successfully as the motor leds light up
correctly. Unfortunately, the buffalo prompt is not displayed again
afterwards.
I then tried loading the IC pcode. When I power cycle the noard and run IC
the program indicates a board not present. If I reset the chip without a
power cycle and then run IC, it just hangs up without displaying a message.
If it is of any help, our current computer is an AMD K6-2 at 300Mhz with
48Mb RAM.
Please help! We are supposed to deliver a fully working handyboard by the
end of the week as a school asignment.
Fernando
Thanks, we hope to hear back from you soon!

If you use MS Windows 95/98/NT hbdl is your best bet as a downloader, since dl or dlm hang up under these OS's, even in a MSDOS terminal window. dl and dlm work (...)
