The init command installs all the required python dependencies for west and initializes the cmake build environment for the STM32 side of the project.

## build
|

The build command builds both sides of the project (if configured), STM32 and Zephyr. It defaults to release mode and both cores when run without arguments.

The build command builds both sides of the project, STM32 and Zephyr. It defaults to release mode when run without arguments.
|
||||
|
||||
Multiple arguments can be passed as follows:
|
||||
```bash
|
||||
--release
|
||||
# or
|
||||
--debug
|
||||
```
|
||||
```bash
|
||||
--clean
|
||||
--CM7
|
||||
--CM4
|
||||
```
|
||||
For example to build clean in debug mode:
|
||||
```bash
|
||||
neoecu build --debug --clean
|
||||
```
|
||||
## flash
|
||||
The flash command will flash the built binaries onto a board connected over JLink. Single core flashing is done using the same arguments as build:
|
||||
```bash
|
||||
--CM7
|
||||
--CM4
|
||||
```
|
||||
If no arguments are provided it defaults to flashing whatever is configured in `neoecu.toml`
|
||||
The flash command will flash the built binaries onto a board connected over JLink. It currently doesn't support per core flashing to it will flash both binaries at once.
|
||||
|
||||
## clean
|

The clean command cleans up all build directories in the project

- Incorrect mkdir command to create the `/opt/SEGGER/Jlink` directory, updated with -p flag
|
||||
- Incorrect command for extracting JLink tarball, updated target to correct directory
|

# Background

|

This document outlines the procedure to recover a bricked Arduino Giga R1 board.
|
||||
|
||||
::: {.callout-important}
|
||||
This guide does **NOT** return the Arduino Giga to its factory state *(ie the ability to flash via USB with the Arduino IDE)*. However it can be applicable as a first step to a factory restore to Arduino defaults.
|
||||
:::
|
||||
|
||||
After having does a few tests with code generated by STM32CubeMX, I once found one of my Arduinos in a seemingly dead state, no signs of life other than the power LED and a daunting error when trying to flash: `Error: Failed to initialize DAP`. After many hours of trying things, I finally managed to figure out how to recover the mcu when it has been flashed with firmware that rendered it lifeless.
|
||||
|
||||
::: {.callout-note}
|
||||
Once the board is recovered, **CHECK** your RCC configuration in STM32CubeMX, it is likely a power configuration issue where RCC tries to power from an external SMPS when it should be set to LDO_INTERNAL
|
||||

|
||||
|
||||
# Recovery
|
||||
## Prerequisites
|
||||
In order to recover the board, you will need the following:
|
||||
|
||||
- STM32CubeProgrammer
|
||||
- A USB-C cable
|
||||
|
||||
## Process
|
||||
|
||||
{width=90%}
|
||||
|
||||
Open up STM32CubeProgrammer and set the connection mode to USB
|
||||
|
||||
{width=80%}
|
||||
|
||||
Then while holding down the `BOOT` button on the Arduino Giga, plug it in. Keep holding the button down for about 5 seconds then release.
|
||||
|
||||
{width=40%}
|
||||
|
||||
Then (1) click the refresh button in STM32CubeProgrammer, you should see a USB device appear, if it doesnt, unplug your board and try the previous step again.
|
||||
|
||||
Once the device is recognized, (2) click on connect to establish a connection to the board.
|
||||
|
||||
{width=90%}
|
||||
|
||||
You can now proceed to a chip erase:
|
||||
1. Open the "Erasing and Programming" window
|
||||
2. Click the "Full chip erase" button, acknowledge any warnings etc
|
||||
3. Once the chip erase is complete, click disconnect
|
||||
|
||||
**Congrats**, you have successfully unbricked your board, you should now be able to connect to it via JLink. Now good luck finding the config fluke that bricked it.
