There isn't necessarily ANY onboard code required to program FLASH, other than the BDM/JTAG drivers onchip directly from Motorola.
The basics of FLASH programming consists of writing command words into command addresses and then writing the data into the desired address (re:AMD's Am29DL16xC pub#21553 Rev. C 08/23/99)... I don't see why one couldn't use MaCraigor's scripting language within the BDM Commander to carry out the entire operation THROUGH the BDM/JTAG keeping all the logic over on the host with no bootstrap code & no secondary ports required (Of Course, the specifics of your FLASH device may vary).

The question is: Using the Macrgraigor flash programmer can we program blank flash, or does some sort of boot strap need to be run in order to configure the on board memory to use the flash programmer? How do you program in production with soldered down flash? I realize this is a general embedded question.
