Hi,

May I know, How to flash the firmware for ATSAM4 which is used for flashing and debugging nRF52840. And also how to get the firmware?

Hi,

The procedure to flash the interface MCU of the nrF52840 PDK is described on this infocenter page.

The J-Link OB IF firmware can be found here.

Best regards,

Jørgen

Jorgen, I need a clarification about firmware. Whether atmel will provide the chip with default segger firmware? And whatever firmware we upgrade it will be stored either in ROM or flash of ATSAM?

Please correct me in the below context:

1. To flash firmware in to ATSAM we need JLINK tool and KEIL IDE for compiling (if required).
2. Supporting segger or mbed firmware can be downloaded from nordic website.
