Re: [Flashforth-devel] building larger program words -- arduino mega2560 FF5

[craig b. <dab...@ya...>]

Fascinating...  Well I just discovered that I haven't got a spare arduino here at home, so I'll either have to run back up to work to try that or wait till Monday.
Do you have any special things added on top of the base install?  I put in core, arrays, forget, math, bits, and asm (not asm2).

Compiles and runs fine on my atmega2560. I replaced both .rdump and
.read with rdump.
Assuming just typos in the mail.

There is no such risk on the Atmegas, and for..next do nest until the
stack is full.

You could run SEE on TRY and see if it decompiles nicely.
There is always a risk of bad flash bits.
FF verifies the flash writes, but you never know.
