For ARM GCC
- Set in /home/he/nrf/components/toolchain/gcc/Makefile.posix
- Set GNU_INSTALL_ROOT ?= /usr/bin/
Compile Blink
- locate file at example folder: /nrf/examples/peripheral/blinky/pca10056/blank/armgcc
- make directly, and output

Setup for DAPLINK for NRF52832
- tick reset and run
- RAM for algothirum, start at 0x20000000, size 0x2000
- Add programming as image
old
- NRF52 Series in Keil
- Project add core and startup
- Options for target: 16mhz, tick "use microLB"
- IROM1: start 0x0 size 0x80000
- IRAM1: 0x20 000 000, size 0x10000
Arduino Support
https://github.com/sandeepmistry/arduino-nRF5
- Require J-Link or DK board, intall mbed driver
- Use sketch -> upload via programmer
https://forum.mysensors.org/topic/9266/guide-nrf5-nrf51-nrf52-for-beginners
- Use mysensor arduino board (ebyte) and arduino nRF5
Arduino NRF52 Flash Guide use Electrodragon DAPLINK
Error and Bugs
For Keil
- Also need to install 8.27, 8.28, 8.29 device family from here https://developer.nordicsemi.com/nRF5_SDK/pieces/nRF_DeviceFamilyPack/
For Arduino Upload Error
- Check if the board in DFU mode, LED blink in 'timebome' sequence
- Disconnect and reconnect FTDI cable
Demo Video
- Send 00 / 01 to control LED - https://www.youtube.com/watch?v=w0axAV4OE-w
