PineTime Smart Watch Logo Loader

Load your Custom Boot Logo to PineTime Smart Watch. Works with the PineTime MCUBoot Bootloader.

If our PineTime is not running on the MCUBoot Bootloader, flash the bootloader with PineTime Updater
Click Fork to fork this repo
In the new repo, click Actions → I Understand My Workflows Enable Them
Click Code → Add File → Upload Files
Upload a PNG image file with the following format...
- Filename pinetime-graphic.png
- 240 x 240 resolution
- 24-bit RGB color
- See sample logos in logos
GitHub Actions will auto-build the firmware (see the workflow)
Click Actions. Click on the latest build.
Wait about 5 minutes for the build to complete.

Click on the Artifact named my_sensor_app.img
Unzip the downloaded file.

Flash the unzipped firmware my_sensor_app.img to PineTime via PineTime Updater at address 0x8000
When the firmware runs, it will write the Boot Logo to PineTime's External SPI Flash.

PineTime will show Boot Logo Updated
Restore the PineTime firmware by flashing the latest InfiniTime firmware via PineTime Updater
PineTime will now boot with the new Boot Logo stored in External SPI Flash...

Automated Build with GitHub Actions

The MCUBoot Bootloader and Rust+Mynewt Firmware are built automatically in the GitHub Cloud.

Just fork this repo, update the source code and the built firmware will be available for download under "Actions".

The Automated Build is performed according to the following GitHub Actions Workflow...

.github/workflows/main.yml

The Worklow is similar to the one described in this article...

Build Instructions

If you are building from this repository from scratch instead of the Released Packages, here are the steps for Linux (including Raspberry Pi) and macOS...

Install Build Tools

Install OpenOCD from The xPack OpenOCD. Older versions of OpenOCD are known to have problems flashing with ST-Link.

Download and unzip OpenOCD for macOS: gnu-mcu-eclipse-openocd-0.10.0-11-20190118-1134-macos.tgz

For Raspberry Pi: Install openocd-spi according to the instructions here...

"OpenOCD on Raspberry Pi: Better with SWD on SPI"
Install GCC and Python build tools for Linux (or the macOS equivalent)...
```
sudo apt install gcc gcc-arm-none-eabi python3 make
```
For Majaro and Arch Linux...
```
sudo pacman -S arm-none-eabi-gcc
```

Install rustup with support for nightly target thumbv7em-none-eabihf.

Follow the instructions at https://rustup.rs/

Press Enter to select 1) Proceed with installation (default)

Then execute...

# Latest nightly-2020-04-20 fails with asm error, so we use nightly-2020-02-16
source $HOME/.cargo/env
rustup update
rustup default nightly
rustup target add thumbv7em-none-eabihf

Install the newt build tool for Mynewt. Refer to these scripts...
- scripts/install-version.sh: To set the version numbers
- scripts/install-pi.sh: To build and install newt, look under the section "Build newt"

Download Source Files

Download the source files to ~/pinetime...

mkdir ~/pinetime
cd ~/pinetime
git clone --recursive https://github.com/lupyuen/pinetime-rust-mynewt

Update the MCUBoot version number to 1.3.1. Edit ~/pinetime/pinetime-rust-mynewt/project.yml

Change...

repository.mcuboot:
    type: github
    vers: 1.5.0

to...

repository.mcuboot:
    type: github
    vers: 1.3.1

Download the source code for Mynewt, NimBLE and MCUBoot...

cd ~/pinetime/pinetime-rust-mynewt
newt install

We should see...

        ext/mbedtls/include/mbedtls/config.h
Please move or remove them before you switch branches.
Aborting

Ignore the mcuboot error above and proceed to the next step.

Restore the MCUBoot version number to 1.5.0. Edit ~/pinetime/pinetime-rust-mynewt/project.yml

Change...

repository.mcuboot:
    type: github
    vers: 1.3.1

to...

repository.mcuboot:
    type: github
    vers: 1.5.0

Download version 1.5.0 of MCUBoot to repos/mcuboot

cd ~/pinetime/pinetime-rust-mynewt/repos
rm -rf mcuboot
git clone --recursive --branch v1.5.0 https://github.com/JuulLabs-OSS/mcuboot

Why are we doing this? Because we are using a more recent version of MCUBoot (1.5.0), but that's not in sync with the older Mynewt version (1.7.0). This will cause newt install to fail. Hence we do this workaround to force Mynewt to build with the newer MCUBoot.

Select the OpenOCD Interface: ST-Link or Raspberry Pi SPI

Edit ~/pinetime/pinetime-rust-mynewt/scripts/config.sh

If we're using ST-Link v2 for flashing PineTime, set swd_device as follows...

#  Select ST-Link v2 as SWD Programmer
swd_device=scripts/nrf52/swd-stlink.ocd

If we're using Raspberry Pi SPI for flashing PineTime, set swd_device as follows...

#  Select Raspberry Pi as SWD Programmer
swd_device=scripts/nrf52-pi/swd-pi.ocd

Flash MCUBoot Bootloader

Edit ~/pinetime/pinetime-rust-mynewt/scripts/nrf52/flash-boot.sh

Change openocd/bin/openocd to the path of our installed openocd (for ST-Link) or openocd-spi (for Raspberry Pi)...

#  Flash the device
openocd/bin/openocd \
    -f $swd_device \
    -f scripts/nrf52/flash-boot.ocd

The path of the built firmware file is defined in ~/pinetime/pinetime-rust-mynewt/scripts/nrf52/flash-boot.ocd. We shouldn't need to change this.

For ST-Link, check that the Adapter Speed is set to 1000 kHz. OpenOCD won't work at higher speeds.
```

If the flashing fails, check whether any openocd processes are running in the background, and kill them.
