How to flash uf2 bootloader / circuitpython on pitaya go #216

Closed rcmz closed 3 years ago

rcmz commented 3 years ago

Hello I’m trying to flash the uf2 bootloader on my pitaya go in order to install circuitpython but I’m having trouble.

If I try to flash pitaya_go_bootloader-0.6.1_s140_6.1.1.zip using this command adafruit-nrfutil dfu serial -pkg pitaya_go_bootloader-0.6.1_s140_6.1.1.zip -p /dev/ttyACM0 -b 115200 I get a serial.serialutil.PortNotOpenError: Attempting to use a port that is not open error

If I use the nrf programmer desktop application and try to write pitaya_go_bootloader-0.6.1_s140_6.1.1.hex I get a DFU failed: Error message for known extended error code from DFU target: The init packet does not contain a signature. This bootloader requires DFU updates to be signed error

Do you know how can I sign the hex / successfully flash the uf2 bootloader ?

Again, generally you will need a external programmer like jlink, but you should try to ask vendor that makes your hw board.
