WinPicProg Forums

Hi, I'm trying to program the microchip usb bootloader software onto a pic18f4550. The code seems to burn and verify ok but I'm thinking there is problem with the configuration bits. I'm unable to get winpicprog to read the bits from the hex file exported from MPLAB so am typing them in by hand (and are subsequently unable to save them from winpicprog either I think).

Anyway, I read on some google cached versions of old winpicprog forums that configbits are modified to suit chip to aid verify and wondering if you can confirm the bits I am trying to use as taken from the configuration bits window of the bootloader mplab project should be able to be programmed onto the chip with winpicprog1.95e:

0e24
1e3f
8100
0081
c00f
a00f
400f

the first bit it refuses to write is the disable watchdog timer which would mean configure word 2 should be 1f3f instead of 1e3f,

thanks in advance for any help

18F support is still very beta, there may be configuration fuse issues!.
