Possible problem with power fail about wolfboot HOT 5 CLOSED

Hey @UffTechn ,

Thanks for reporting this.

Your approach seems valid. The fork_bootloader() should do nothing if the contents already match. Which means it should only run once after the installation. Which would be equivalent (after the first run) to your current approach of flashing wolfBoot at the beginning of both banks.

I'm going to open a PR to address this the right way and update the porting documentation for the fork_bootloader() feature.

@UffTechn I changed the fork_bootloader call so that it returns immediately if the content in the second bank already matches. Please confirm this would solve your case, and regardless whether you want to upload the bootloader to both banks you should not need to comment out the invocation of the fork_bootloader() call.

Could you confirm this is a valid fix for your use case?

Thanks,
