Hello there,

I am working on an application now, where I need to send a command to the mcu through USB in order to reset the mcu and jump to system memory bootloader. On my board boot1 is shorted to ground, that means if I reset the mcu with boot1 pulled up, the system starts from bootloader. User however wont have access to boot1 phisically, so before watchdog reset I need to set boot1 in software somehow. Is that possible? I would apreciate all help!

    I get the overal concept, but my application is kind of tricky. I basically have to jump to bootloader on demand from user application. I cannot perform any additional actions during boot time of the machine or etc. That is the problem.
