This document is very much a work in progress, None of it is warranted as Correct, Accurate or Optimal.. Suggestions very welcome.

Requirements

• PineTime Dev kit
• ST-Link programmer
• POGO Pin connector for ST-LINK or soldering skills

Setup OpenOCD to use the ST-Link

Triple check the wiring! The wiring on this page is misleading

https://github.com/InfiniTimeOrg/InfiniTime/blob/develop/doc/openOCD.md

Better wiring info here

https://wiki.pine64.org/wiki/PineTime_Devkit_Wiring

Simple Updater - To check ST-Link is working

https://github.com/lupyuen/pinetime-updater

cd ~/Documents/PineTime/pinetime-updater
./run.sh

https://github.com/InfiniTimeOrg/InfiniTime/blob/develop/doc/buildAndProgram.md

Dependencies

Environment setup

Install

CMake - Build make configurations

https://zbm2.com/dokuwiki/doku.php?id=pinetime_introductionhttps://zbm2.com/dokuwiki/doku.php?id=pinetime_introduction
cd ~/Documents/PineTime/InfiniTime/build
 
cmake -DARM_NONE_EABI_TOOLCHAIN_PATH=/opt/gcc-arm-none-eabi-9-2020-q2-update/ -DNRF5_SDK_PATH=/opt/nRFSDK -DUSE_OPENOCD=1  ../

Seems to ignore ST-Link flags(?)

Make - Build the firmware with the support of the bootloader (based on MCUBoot)

https://github.com/InfiniTimeOrg/InfiniTime/blob/develop/bootloader/README.md

make -j pinetime-mcuboot-app

Flash Config File - flash_bootloader_app.ocd

init
 
program /home/nicolas/Documents/PineTime/InfiniTime/build/src/pinetime-mcuboot-app-image-1.8.0.bin verify 0x00008000
 
reset

Flash

cd ~/Documents/PineTime
sudo openocd -f ./openocd-stlink.ocd -f ./flash_bootloader_app.ocd

Github Cloud Build

With the build working locally from the command line I tried this Github cloud build. Note these articles are old and things have moved on.

https://lupyuen.github.io/pinetime-rust-mynewt/articles/cloud#add-github-actions-to-our-fork

I used the develop work flow main.yml on my fork, all runs well.

nRF Connect For Mobile app to upload the DFU file or use GadgetBridge.

VSCode Setup

https://github.com/InfiniTimeOrg/InfiniTime/blob/develop/doc/buildWithVScode.md

pip3 install –user adafruit-nrfutil

Ensure the MCUBoot python tools are already installed

Cmake tools extension configuration

Cmake: Configure Environment Environment variables to pass to CMake during configure.

ARM_NONE_EABI_TOOLCHAIN_PATH /opt/gcc-arm-none-eabi-9-2020-q2-update NRF5_SDK_PATH /opt/nRFSDK

C_cpp_properties.json

“compilerPath”: “/opt/gcc-arm-none-eabi-9-2020-q2-update/bin/arm-none-eabi-gcc”,

Build

Successfully builds from VSCode

https://github.com/InfiniTimeOrg/InfiniSim

Build simulator version

cd ~/Documents/PineTimeSim/InfiniSim
cmake -S . -B build
cmake --build build -j4 --clean-first # Clean first if needed

Run simulator

./build/infinisim --hide-status

Commands

Left mouse button: simulates your finger, just click to tap, click and drag to swipe Right mouse button: simulates the hardware button (for example turn the screen off or on again)

Using the keyboard the following events can be triggered:

r … enable ringing R … disable ringing m … let motor run for 100 ms M … let motor run for 255 ms n … send notification N … clear all notifications b … connect Bluetooth B … disconnect Bluetooth v … increase battery voltage and percentage V … decrease battery voltage and percentage c … charging, C … not charging l … increase brightness level L … lower brightness level p … enable print lvgl memory usage to terminal P … disable print memory usage s … increase step count by 500 steps S … decrease step count by 500 steps h … set heartrate running, and on further presses increase by 10 bpm H … stop heartrate

Next

• Debugging?
• Shake to refresh app view
• Multiple BLE connections? Handling of BLE messages
• Make hard wired powered dev board?

Notes to be looked at!

[T] <KieranC> pinetime-mcuboot-app.bin is different from pinetime-mcuboot-app-image.bin, the latter contains a header which is needed to boot using the bootloader [T] <Avamander> pinetime-app.bin however you can flash at 0x0 and it replaces/skips the bootloader, nice fast debugging! [T] <KieranC> You can flash the former at 0x0 and boot without the bootloader but it won't boot if flashed at 0x8 [T] <Jasmin2o22> Thx mate, perfect (re @KieranC: [M] <jf002> > <@p64protocolbot4:matrix.org> [T] <KieranC> Forwarded from KieranC: I'm doing openocd -f interface/stlink.cfg -f target/nrf52.cfg -c 'init' -c 'program bootloader.bin' -c 'reset' then openocd -f interface/stlink.cfg -f target/nrf52.cfg -c 'init' -c 'program src/pinetime-mcuboot-app-1.6.0.bin' -c 'reset' You need to flash a file called pinetime
