Re: [Flashforth-devel] Question about running FlashForth on Arduino Diecimila

[Mikael N. <mik...@fl...>]

At least in AVRSIM2 the XH register in the code sequence
below fails count over 0x08 on the 168p.
So FF gets stuck in an infinite loop just at the startup.
Even if XH is a 16 bit regsister.

In atmega source file
Try replacing this

WARM_2:
         st      x+, r_zero
         cpi     xh, 0x10  ; up to 0xfff, 4 Kbytes
         brne    WARM_2


With THIS:

WARM_2:
         st      x+, r_zero
         cpi     xh, 0x04  ; up to 0x3ff, 1 Kbytes
         brne    WARM_2

It may help also on the real hardware.
