# nrf52-baseproject
|
|
This is a CMake project that configure everything needed to build applications for the NRF52 MCU. It configures the toolchain (arm-none-eabi) and the NRF52 SDK.
|
|
|
|
The CMake files are taken from https://github.com/Polidea/cmake-nRF5x
|
|
|
|
I tested this project (compile only) with the following versions:
|
|
|
|
* gcc-arm-none-eabi-8-2019-q3-update (from https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads)
|
|
* nRF5_SDK_15.3.0_59ac345 (from https://www.nordicsemi.com/Software-and-Tools/Software/nRF5-SDK)
|
|
|
|
I've tested this project on the NRF52-DK board.
|
|
|
|
## How to use it
|
|
|
|
* Download and unzip arm-none-eabi and NRF52 SDK
|
|
* Clone this repo
|
|
* Call CMake with the following command line argument
|
|
|
|
- -DARM_NONE_EABI_TOOLCHAIN_PATH=[Path to the toolchain]
|
|
- -DNRF5_SDK_PATH=[Path to the SDK]
|
|
- -DNRFJPROG=[Path to NRFJProg]
|
|
|
|
```
|
|
$ mkdir build
|
|
$ cd build
|
|
$ cmake -DCMAKE_BUILD_TYPE=Debug -DARM_NONE_EABI_TOOLCHAIN_PATH=... -DNRF5_SDK_PATH=... -DNRFJPROG=... ../
|
|
```
|
|
|
|
* Make
|
|
```
|
|
$ make -j
|
|
```

## RTT
|
|
|
|
RTT is a feature from Segger's JLink devices that allows bidirectionnal communication between the debugger and the target.
|
|
This feature can be used to get the logs from the embedded software on the development computer.
|
|
|
|
* Program the MCU with the code (see above)
|
|
* Start JLinkExe
|
|
|
|
```
|
|
$ JLinkExe -device nrf52 -if swd -speed 4000 -autoconnect 1
|
|
```
|
|
|
|
* Start JLinkRTTClient
|
|
|
|
```
|
|
$ JLinkRTTClient
|
|
``` |
