Flash NRF52 by UART

[Flavien]

Hi everyone,

I would like to create my board like this one :

www.adafruit.com/.../3406

learn.adafruit.com/.../39913

I know that Adafruit changed the bootloader in them NRF52, so I would like to know if I can flash my nrf52 by UART without change the bootloader ??

Thx for reading,

Best regard,

Flavien

@Flavien, the nRF5x cannot be programmed via UART but you can use the IDAP-Link with Arduino IDE to program nRF chip. I have tested it myself sometimes ago. I may able to help to set it up.

Yes, you should only need (SWDIO, SWCLK, VCC and GND) to program the device. Also remember to power your nRF52 device!

• VDD: Reference voltage for programmer
• SWDIO: Serial wire debug data
• GND: Ground
• SWDCLK: Serial wire debug clock
