Hi,

I am trying to program a 12C508A with a simple morse code program and
here is what happens.

I am using icprog v. 105c with the 508 dll included, and I have a
JDM programmer.

I open icprog

I set device to 12C508A

I set osc to internal rc

I load the hex file into icprog

I press program all

icprog reads the config and then comes up with the following
warning "no oscillator value found. Do you want to use value from
file (0fffh) instead?"

Whether I press yes or no it continues on and says programming code.

Then it comes up with the error: "failed to verify at address 0000h.

What am I doing wrong?

Any help would be greatly appreciated.

Regards,
Sheeraz Khan
 

pic 12C508A and jdm hawe a problem .let see shematic of the programer.
tray winpic800 as software,or pony prog.
 

when a programmer write's the code block hex to your chip
it first reads the config from the hex you added in your code
usualy as a config_ etc etc.....

failing to define the frequency of the internal clock
will have the effect your describing

and becouse there is a fail to set it icprog then fails to write the code
and you get the chicken egg.. second error
becouse the code isnt there then the chip also cant be varified

check this sources config in this guys source to confirm your setting in asm
