Re: [Flashforth-devel] PIC18 has been updated to compile with PIC-AS

[Peter J. <pe...@me...>]

Mikael,
I dusted off my other boards and updated those build and install sections.
https://pajacobs-ghub.github.io/flashforth/ff5-tutorial-guide.html#_building_for_the_pic24fv32ka302

I also tried to build and use FF on a PIC18F16Q40 by adapting your 
config for a 16Q41.  Although I got the chip programmed and the 
interpreter starting ok, it would not write new definitions to flash 
memory.  Here is a sample of the session with the programmer still 
attached to the ICSP pins. After exercising words, I sent a file 
containing my little flash-led text.

When I remove the programmer and power up the microcontroller, it resets 
itself every couple of seconds.

Any hints as to what I am doing wrong? I have the microcontroller 
mounted on a bit of strip-board with the bare minimum of support so I 
may not be giving it the electrical environment that it needs.  I will 
need to give it some thought...

Cheers,
