Hi, Is there an other way to force the core to go in DFU mode for flashing (instead of mode+reset button combi) in order to speed up and automate flashing locally during development. That would reduce test cycles. Thanks

Hey @focsic , Yes! The easiest way to do this is to add the following define to your local build: #define DFU_BUILD_ENABLE You can also tell the bootloader your code shouldn’t be run again, and to reboot into dfu mode with the following code. This way your firmware could receive a message, and r…

Thanks Dave, will try it out. Any idea where’s the bootloader code ? I found old ref to https://github.com/spark/bootloader but doesn’t exist anymore apparently.

Hey @focsic , That code I provided can be run directly from the normal user-space firmware, it communicates with the bootloader by manipulating flags that it checks. You are correct that the bootloader repo is here: https://github.com/spark/bootloader We plan on releasing it again, but we were hop…
