" From: Peter Stokes <peter at ashlyn.co.uk>
" I guess there is a way of mapping the boot rom into memory space and running a
" forth loop to print the contents from the ok prompt on a serial console such
" as Putty, then copy/paste the results to give a binary hex output, but no idea
" of the mapping or the forth loop required, maybe someone here can help?
this puts me in mind of a little program i ran as part of bootup on my
eeprom 'nvramrc=probe-all install-console
: cache-page dup pgmap@ cacheable swap pgmap! ;
here origin do i cache-page pagesize +loop
its objective was to run warm boots out of ram, as it was faster than
bootrom. i got this from somewhere and only vaguely understand how it
works; i have only the most superficial knowledge of forth but perhaps
it holds a clue.
