To write a program from the Arduino IDE to the NINA-B306 module

Official Hardware Nano Family Nano 33 BLE Sense

Hello.
How can I write a program from the Arduino IDE to the NINA-B306 module and use it?
In other words, I want to use the NINA-B306 module alone like using the Arduino nano 33 BLE Sense.
Please give me hints.

you have to put the Arduino bootloader (or the Adafruit bootloader) into the nRF52 wth an SWD programmer

Thanks for your prompt reply. I'm happy.
Is the Arduino bootloader the same as written for the Arduino uno?
Or is there a different bootloader for each type of board?

different. it can be 'burned-in' with Arduino IDE, but you need a hardware programmer for ARM.

Thank you Juraj! I can write nano33ble bootloader to NINA-B306 through Arduino and SWD programmer, right? I check where on the NINA-B306 module the SWD pins correspond.

Jumping on this thread since I’m working on something similar.

After flashing the nano 33 ble bootloader, can one control the gpios using standard pinMode, digitalWrite, etc?

I’m also wondering how I might use I2C with a NINA on a custom board, if the I2C pins I use don’t match the ones on the Arduino Nano BLE 33.

Is there a boards definition file I can modify? Where to find it?

Thanks
