Help on programming bootloader to PIC18f452 with Willem PCB5.0

Testing/Troubleshooting
1

Hello to all.

Today i spent the entire day on programming the PIC18f452.

Nothing worked!  :frowning: ???

This is what i have and what i did.

Hardware: Pentium4 2.40ghz - 992RAM (plus the videoRam on board) with Windows Server 2003®

A short Parallel cable on LPT1 port with ECP/EPP enabled

Programmer: Willem PCB5.0 (powered by USB)

PIC: 18f452  (For a MIDIbox SID single core) Tried 4 different Pics

Software:

  • Original Willem Eprom PCB5.0 Ver. 0.98D8
  • IC-PROG 1.06b either with and without the icprog.sys driver
  • WinPIC compiled in August 2008
  • WinPic800 ver 3.64

With all of these applications i can read/erase the Pic, but i cannot program.

The standar error is at the 000000h address.

Tried all kind of delay settings, also i used the API (but i think they go on only with USB).

WinPic800 says: ERROR-> Writing address 0x000000 Written: 0xEF06  Read: 0x0000

Willem Eprom PCB5.0 Ver. 0.98D8 says: ERROR Program memory at 0x000000

Below you can read the WinPic log

I’ve read others treads about 000000h error but i really didn’t find anything useful or maybe i didn’t understand, i need help on testing the mclr voltage, i don’t know how to do it. I mean that i don’t know where to put the Ground probe of the Voltmeter.

Also what other stuff i must check?

On the Willem Eprom PCB5.0 Ver. 0.98D8 there are two weird settings: tWP (uS value) and tWC (mS value). Don’t know what they mean.

Thanks to all,I hope you could help me.

Hi

Read in some forums:

  • better to use a 12V AC  adapter instead of USB, or powered from other’s computer’s USB port,

  • tWC= 8-10, tWP=30

There are many fuses for Pic Mcu’s too

Be patient

Regards, Janis

Thanks, i tried with the external psu (both AC and DC at 12v) but it didn’t work.

Also tWP=30 cannot be assigned to the Original Willem Eprom PCB5.0 Ver. 0.98D8 software, maximum is 13.0mS.

If someone could help me on testing the voltage while the Pic is programmed… I dunno where to put the Voltmeter probes.

You can read about programming voltage testing for Pic Burner in Uccaps too.

“+” probe to Pin 1 , MCLR

“-” probe to Pin12 or Pin31, GND , both pins are connected.

For everybody that come to this post, an update:

I’ve tried the Willem PCB5.0 with the ICSP connection to the 18F452 with a breadboard and some resistors like described here http://www.tinet.cat/~sag/pic452.htm. It seems that the Willem application can listen to the PIC without the identification, i’ve tried to burn a PIC without goal.

Thereafter i decided to etch the PicBurner module and i used that to burn some PICs without problems, so my suggestion is to use the PicBurner.

Regards.

Yes indoodlydeedly.

Often the simpler solutions work better.

good burning
