The 177Bug Debugger Command Set

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.
