I will appreciate help with this.
Spent days and can not get the bootloader to work at all. With a C program, comms Tx and Rx works and the MCP2200 Usb to serial converter works 100%.
I have tried just every option with clock speeds, configurations, etc. I also tried it with the latest bootload version.
The Osc is running 64000000 with the PLL but the code gives an error and I therefore switch off the PLL to run 16000000 hz.
Here is my user setup, changed to enable the MCP2200 and a led, tried with and without the OSCCON setup:
USER_CODE.INC:
SETTINGS.INC:
Attached is the code listing...
