I need help with a pic 12c508a

Started by bruce_shurtz September 20, 2003
Hi,

I am new to pics and programming so please bear with me.

I am trying to program a 508a 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 (which is what I want)

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.

Thanks,

Bruce



Bruce,

I suffered the exact same problem trying to program a 12C671. Built a
JDM programmer and this happened. Then bought one, same problem.
Built another type of JDM, no luck.

Gave up and bought a Microchip PicKit1 Flash starter kit - glad I
did. USB programmer and it programs a range of 8/14 pin flash devices
(not like the crappy one time programmable jobbies!)
