[fpc-devel] Is target mips-embedded possible / planned?

If you install some software on the target for self-programming, you of 
course can use any (serial) interface to transfer the user software and 
burn it into the Chip's Flash. That way an USB-to-serial Adapter 
providing async, SPI and/or I²C offers perfect speed. (As the serial USB 
Adapter you can use the PICKit hardware which is rather cheap and comes 
from Microchip pre-programmed with the appropriate firmware as "Serial 
Dongle" or similar.

Of course you can't (easily) do debugging via such a serial interface. 
here using the debug hardware built in the chip seems much more 

The debugging (and "hardware" Flash programming) pins of the PIC chips 
are not necessary handled in a "bit-banging via USB" mode. The ICD-3 
Adapter (but supposedly not the PICKit) uses internal intelligence here 
and the image to be programmed is transferred in blocks of bytes via USB.
