PIC 18F2520 problem [solved]
#1
Hello,

I am trying to run the bootloader on a 18F2520 @ 20Mhz.

I have changed the settings.inc file (see below) and programed the .hex with my WISP628.

When i want to connect with the PIC i run the DS30loader GUI, press on the "check for bl" and reset the pic by pulling the MCLR low. But after 10 seconds i can see : seraching fot bl ................... time out


what do i wrong?

Hi,


Problem solved. The solution came from a dutch form : http://www.circuitsonline.net/forum/view...00#1197700

The way i did change the configuration in the attached picture wasn't the right way. I changed the configuration bits at the end of te settings file.

Bootloader looks great Smile
