[Elecraft] Fwd: K3 Failed DSP Firmware Download

[Dick Dievendorff]

The PIC18F8722 microcontroller used has 128KB of flash program memory and a bit less than 4KB of RAM. Its a Harvard architecture machine, not the Von Neumann model. Your "simple" suggestion is infeasible. There is no place on chip to buffer the firmware in its entirety.
