Re: Feb 6 - Day 3 – Bootloader Firmware Design

NO RATINGS

Yes, the MAL have been very helpful!

Is there a way to fail over to another hex file or another image (perhaps the last known good image) if BootApplication() fails?

 

@N3WWN: Yes..It's a simple matter of programming :-) For simplicity, I loaded a single .hex file to the microSD.  You can have multiple files on the microSD all with differing images.

Instead of just collecting the one expected file, you could scan for them all and select the one you wish to load. If BootApplication() failed, you have had a catastrophic error occur and the NUKE button (ABORT) would have to be brought into play.
