This folder contains differnt scripts that automates routine actions.
|
|
|
|
|
Flashing scripts are based on cli version of [STM32CubeProgrammer](https://www.st.com/en/development-tools/stm32cubeprog.html).
|
|
|
|
|
You will need to add STM32_Programmer_CLI to your path to use them.

# Flashing empty MCU/Flipper
|
|
|
|
|
|
|
|
|
|
Always flash your device in the folllowing sequence:
|
|
|
|
|
|
|
|
|
|
- OTP (Only on empty MCU)
|
|
|
|
|
- Core2 firmware
|
|
|
|
|
- Core1 firmware
|
|
|
|
|
- Option Bytes
|
|
|
|

## Otp flashing
|
|
|
|
|
|
|
|
|
|
!!! Flashing incorrect OTP may permanently brick your device !!!
|
|
|
|
|
|
|
|
|
|
Normally OTP data generated and flashed at factory.
|
|
|
|
|
In case if MCU was replaced you'll need correct OTP data to be able to use companion applications.
|
|
|
|
|
Use `otp.py` to generate OTP data and `flash_otp_version_*` to flash OTP zone.
|
|
|
|
|
You will need exact main board revision to genrate OTP data. It can be found on main PCB.

## Core2 flashing
|
|
|
|
|
|
|
|
|
|
Script blindly updates FUS and Radiostack. This operation is going to corrupt bootloader and firmware.
|
|
|
|
|
Reflash Core1 after Core2.
|
|
|
|
|
|
|
|
|
|
## Core1 flashing
|
|
|
|
|
|
|
|
|
|
Script compiles and flashes both bootloader and firmware.
|
|
|
|
|
|
|
|
|
|
## Option Bytes
|
|
|
|
|
|
|
|
|
|
!!! Setting incorrect Otion Bytes may brick your MCU !!!
|
|
|
|
|
|
|
|
|
|
Defaults are mostly OK, but there are couple things that we'd like to tune.
|
|
|
|
|
Also OB may be damaged, so we've made couple scripts to check and set option bytes.
