on Atmega32u4 the caterina bootloader implements a "doube tap reset" detection so that bootlaoder enters in perpetual mode when reset button is press twice within 1 second. This is very convenient and due to reliability issue of the STM32Duino USB bootlader on OSX, which very often fail to find DFU or fail to uplaoad, i would like to be able to set perpetual bootlaoder mode easily. I know there is an IO for this but board already have a double dip swich for BOOT0 and fast charge and a reset push button.
Does anyone know how to detect double reset and set the bootloader flag accordingly (:in perpetual mode)?
Also, i imported the bootloader project into Systemworkbench (because working on it with command lines and make file is unnecesary painful) it does compile and uplaod fine however i never got it to work. The same compiled with the makefile does work normally.
I suspect some "optimisations" are the cause of this, did anyone get it to work after compilation and upload under systemworkbench?
