Additionally, both of these PFLASH commands do the same thing
when J8 is removed as they do when J8 is installed, regardless of
any SFLASH command that may have been executed. In the case
where the bug is programming over itself the user will not regain
the bug prompt. Successful programming is indicated by the FAIL
LED blinking twice per second. If the programming fails or if the
programmed image is corrupted then it is likely that the bug image
in lower flash is corrupted and the only recourse is to replace J8 and
execute the bug from ROM.
For additional information on the PFLASH command consult the
Debugging Package for Motorola 68K CISC CPUs UserÕs Manual.
