Hello,

i have the same problem with the Error at address 0x0000.

First i checked the hardware (Ram,Latch...) but i cant't find a bug.

In the archive i found this message that descibe a softwarebug on faster
machines.
But i tested HBDL with a P133 and P60. With the same wrong result :-(

I think this machines are slow enough ;-)

Has anybody some other ideas what's happen?

sincerely

Dear Jacob,

the same problem i have solved 4 days. Is solved now, but must prepare the
new files ready to send to others.

Now i can recommend.

1. There is a SW waiting loop which length is short for quicker CPU.
2. Use a Pentium till 200 MHz for downloading with the HBDL.EXE
3. Use a Pentium till 150 MHz for downloading with Charles Hacker
     HandyBoard.exe

Hello,

I've made it up to step 6.0.5 of assembling my first handyboard.  I
purchased the unassembled components from Patrick Hui, so there may be 1 • or
2 substitutes, but everything's gone smoothly so far.  All previous
assembly and testing steps have been completed successfully.

When I power the board on, the 16 blocks appear on the LCD.  They aren't
faint though, they're pretty dark.  The yellow charge LED flashes
continuously.

I power on while holding Stop to get into bootstrap mode.  The 16 dark
blocks appear on the LCD, and the charge LED doesn't flash.

I run HBDL and choose to download pcode_hb.s19.  The monitor downloads
successfully, but as soon as the code begins to download I get the
following message from HBDL: "Error at address 0x000"
....

Hi, That error message is actually to do with a fault in the Borland Delphi code for serial transfer, NOT a fault with the HandyBoard!

This was the case for the error that I was getting. I switched to a slower machine and things worked after that. -Jake ---...--- Forwarded by Jacob Levirne/Trilogy on 09/08/1999 03:57 PM ---...--- "Dvorak Viktor" <dvorakv@cesnet.cz> on 08/28/1999 (...)
