I just bought a NANO 33 IOT. I was trying to run Micropython and was following this document https://docs.arduino.cc/tutorials/nano-33-ble/getting-started-omv.
One of the instruction is to do the below one and when i load the script in IDE and hit upload
en, open: **File>Examples>Nano33_System>Nano33_updateBLandSoftDevice
I get the below errors. on the board the greenlight is stable and yellow is slowly blinking
