PIC to PIC Bootloader feasibility question

[davefromnj]

Hello,

I have a quick question regarding PIC bootloaders:

Let's say I have a test fixture that has a PIC with MSSP, its own test program, and the latest version of the code for the PIC in a separate board.


If I was to develop, then install a bootloader in the separate board, is it possible / feasible to have the test fixture PIC send the latest version of the code to the PIC in the separate board?


I read in another post that perhaps the flow control necessary to write from the test fixture PIC to the separate PIC would be very slow since the separate PIC has to stop executing instructions to self-write to its own FLASH Memory.


I was thinking that it would work like:

Separate PIC receives command that a new version of firmware is available. Test Fixture PIC then begins to stream the firmware to the Separate PIC over I2C.



Should I just avoid this approach all together?

Yes this is possible - in fact this product does just that...
