I am using the Picaxe Programming Editor to download programs to the AXE090 Experimenter Board with a 08M Picaxe chip. The program will download on the first attempt without any problem. Any further downloads usually will fail with an "ERROR - Memory verification failed. (Byte 255)" message. See attachment.
I have:
reset the 08M chip by momentarily disconnecting the power.
used a Picaxe - 18X chip.
used two different versions of the Picaxe Programming Editor.
checked the continuity of the AXE026 serial cable.
checked the placement, solder connections, shorts, etc. of the AXE090.
used two different com ports on my computer.
used different baud rates for these ports.
used a 9v ac wall transformer plugged into the jack on the AXE090.
used the battery pack for power.
Now I have run out of ideas. Does anyone know why I keep getting the error message?
The Program Editor greys out the Com1 port even though I have no programs using it. I would like to try using Com1 for downloading. How can I get the Program Editor to allow me to use Com1?
Thanks,
Rich
