Circuitpython without uf2 bootloader?

by criznach_bms on Mon Apr 19, 2021 12:48 pm

Is it possible to run circuitpython on a SAMD21 board without the uf2 bootloader? I'm finding that it takes around 5 seconds for code to start running on my board, and I need it to handle a power-on button press. Currently it isn't going to work. I even switched a gpio pin on in the board_init() function and recompiled, and strangely that pin gets toggled on and off several times during boot. Does board_init() get called multiple times?
