|
|
|
Welcome to [Flipper Zero](https://flipperzero.one/)'s Firmware repo!
|
|
Our goal is to create nice and clean code with good documentation, to make it a pleasure for everyone to work with.
|
|
|
|
# Update firmware
|
|
|
|
[Get Latest Firmware from Update Server](https://update.flipperzero.one/)
|
|
|
|
|
|
Flipper Zero's firmware consists of three components:
|
|
|
|
- Core2 firmware set - proprietary components by ST: FUS + radio stack.
|
|
- Core1 Bootloader - controls basic hardware initialization and loads firmware
|
|
- Core1 Firmware - HAL + OS + Drivers + Applications
|
|
|
|
All 3 of them must be flashed in order described.
|
|
|
|
## With STLink
|
|
|
|
### Core2 flashing procedures
|
|
|
|
Prerequisites:
|
|
|
|
- Linux / macOS
|
|
- Terminal
|
|
- STM32_Programmer_CLI added to $PATH
|
|
|
|
One liner: `./flash_core2_ble.sh`
|
|
|
|
### Core1 Bootloader + Firmware
|
|
|
|
Prerequisites:
|
|
|
|
- Linux / macOS
|
|
- Terminal
|
|
- [arm-gcc-none-eabi](https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads)
|
|
- openocd
|
|
|
|
One liner: `./flash_core1_main.sh`
|
|
|
|
## With USB DFU
|
|
|
|
1. Download latest [Firmware](https://update.flipperzero.one)
|
|
|
|
2. Reboot Flipper to Bootloader
|
|
- Press and hold `← Left` + `↩ Back` for reset
|
|
- Release `↩ Back` and keep holding `← Left` until blue LED lights up
|
|
- Release `← Left`
|
|
<!--  -->
|
|
|
|
3. Run `dfu-util -D full.dfu -a 0`
|
|
|
|
# Build from source
|
|
|
|
## Prerequisites
|
|
|
|
1. Install [Docker Engine and Docker Compose](https://www.docker.com/get-started)
|
|
2. Clone the repo:
|
|
```sh
|
|
git clone https://github.com/flipperdevices/flipperzero-firmware
|
|
cd flipperzero-firmware
|
|
```
|
|
3. Prepare the container:
|
|
```sh
|
|
docker-compose up -d
|
|
```
|
|
|
|
## Compile everything
|
|
|
|
```sh
|
|
docker-compose exec dev make -j$(nproc)
|
|
```
|
|
|
|
## Flash everything
|
|
|
|
```sh
|
|
docker-compose exec dev make -j$(nproc) whole
|
|
```
|
|
|
|
## Compile bootloader
|
|
|
|
```sh
|
|
docker-compose exec dev make -j$(nproc) -C bootloader
|
|
```
|
|
|
|
Bootloader compilation results:
|
|
* `bootloader/.obj/f7/bootloader.elf`
|
|
* `bootloader/.obj/f7/bootloader.hex`
|
|
* `bootloader/.obj/f7/bootloader.bin`
|
|
* **`bootloader/.obj/f7/bootloader.dfu`** - should be used to flash
|
|
|
|
## Compile firmware
|
|
|
|
```sh
|
|
docker-compose exec dev make -j$(nproc) -C firmware
|
|
```
|
|
|
|
Firmware compilation results:
|
|
* `firmware/.obj/f7/firmware.elf`
|
|
* `firmware/.obj/f7/firmware.hex`
|
|
* `firmware/.obj/f7/firmware.bin`
|
|
* **`firmware/.obj/f7/firmware.dfu`** - should be used to flash
|
|
|
|
## Concatenate bootloader and firmware
|
|
|
|
You might want to do this to distribute the firmware as a single file.
|
|
|
|
That's exactly how we generate our `full` builds.
|
|
|
|
1. Concatenate HEX files:
|
|
```sh
|
|
docker-compose exec dev srec_cat \
|
|
bootloader/.obj/f7/bootloader.hex -Intel \
|
|
firmware/.obj/f7/firmware.hex -Intel \
|
|
-o firmware/.obj/f7/full.hex -Intel
|
|
```
|
|
2. Convert HEX to DFU:
|
|
```sh
|
|
docker-compose exec dev hex2dfu \
|
|
-i firmware/.obj/f7/full.hex \
|
|
-o firmware/.obj/f7/full.dfu \
|
|
-l "Flipper Zero F7"
|
|
```
|
|
|
|
Finally, you will have **`firmware/.obj/f7/full.dfu`** file that can be distributed and flashed.
