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:
Code:
; UserInit()
; Description: this is executed immediately on start-up before the boot loader code
;------------------------------------------------------------------------------
UserInit macro
; enable MCP2200
movlw b'11110110' ; setup clock to 16M clock speed
movwf OSCCON
bcf 0x0F93,6 ; tris B6 out
bcf 0x0F81,6 ; pin B6 // ce low
bsf 0x0F81,6 ; pin B6 // ce high
bcf 0x0F93,4 ; tris B4 out
bsf 0x0F81,4 ; pin B4 blue led
;

I am trying to run PIC18F firmware on PIC18F14K22 too.
I have changed settings.inc file like this;
