OpenSK source recover without reset button. about opensk HOT 5 CLOSED

I already mentioned this here, that's the 2nd bullet point: #81 (comment)

On the Makerdiary, if I'm correct, maintaining the button pressed while inserting the dongle does the job. I tried many things with the Nordic dongle without any luck so far. I have to look on the source code which button/GPIO they assigned to this feature.

I'm in the same position, I flashed my dongle and didn't succeed but I lost DFU mode. I've currently got micropython on there which I've flashed with SWD (nucleo). But I'd like to get my DFU mode back so I can try the new deploy.py you're working on.

Looking at schematic I see RESET is attached to GPIO 0.18, 0.19, 0.21, 0.23 and 0.25 so I'm guessing pulling any of those LOW would trigger DFU mode if using the nordic DFU trigger library

But , how to use nordic dfu trigger library in opensk source code ?

Have you solved this problem？ I have checked nordic office doc some days,and no ideas

This is a feature of the Makerdiary / Adafruit bootloader. It claims to work on the Nordic boards as well.

On the Nordic PCA10059 Dongle board, DFU is connected to the white button. FRST is connected to pin 1.10. Ground it to pull FRST low, as if you had pushed an FRST button. There is an adjacent ground pad.
