IMM-NRF52840 module Quick Start Requirements The follows are required for software development • • • Debug J-Tag : IDAP-Link, Segger J-Link, or any ARM compatible J-Tag. Nordic SDK for ANT, BLE, Zigbee, Thread stack (https://developer.nordicsemi.com/) C/C++ embedded software development environment : Eclipse, Keil, CrossWorks, ... Flashing firmware The Nordic Softdevice is required to use ANT, BLE, Zigbee, Thread application. There are many methods to flash it in the module.
IMM-NRF52840 module J-Tag wiring The IMM-NRF52840 module has exposed the SWD (Serial Wire Debug) pins SWDIO & SWCLK, see I/O layout section. The module can be directly connected to a J-Tag tool for development by wiring the 2 SWD and the optional Reset pins to the appropriate pins on the J-Tag connector. The VIN must be wire to the VCC pin on the J-Tag. GND pad is also require to be connected to GND on J-Tag. Fig.
