* Boot: switch to DFU routines. Implements #132 part 1 of 2. * Boot: boot to DFU shortcut, hard reset USB on each boot. Implements #132 part 2 of 2. * Deploy scripts: fix path for deploy dfu. * Bootloader: initial version. Target_f2: rebase, update deployment scripts. * Bootloader: cleanup, refactor switch2 proc. Readme,wiki: document bootloader. * Wiki: deploy symlinks as files, bootloader info. * Target_f2: valid flash size in linker script. * Github CI: bootloader build and artifacts. * Bootloader: rename platforms to targets. * Bootloader: change dfu/os colors. * disable set -e * lint code * add bootloader testing page Co-authored-by: Aleksandr Kutuzov <aku@plooks.com> Co-authored-by: aanper <mail@s3f.ru>

# Building
|
||||
|
||||
## With dev docker image:
|
||||
|
||||
`docker-compose exec dev make -C bootloader`
|
||||
|
||||
## With toolchain installed in path:
|
||||
|
||||
`make`
|
||||
|
||||
## Build Options
|
||||
|
||||
- `DEBUG` - 0/1 - enable or disable debug build. Default is 1.
|
||||
- `TARGET` - string - target to build. Default is `f2`.
|
||||
|
||||
# Flashing
|
||||
|
||||
Using stlink(st-flash):
|
||||
|
||||
`make flash`
|
||||
|
||||
# Debug
|
||||
|
||||
Using stlink (st-util + gdb):
|
||||
|
||||
`make debug`

# Bootloader
|
||||
|
||||
For production targets('target_f2' and newer) bootloader must be flashed first.
|
||||
Detailed instruction on how to compile and flash you can find in `bootloader` fodler.
|
||||
|
||||
Production version will have following features:
|
||||
|
||||
- Hardware initialization
|
||||
- Firmware CRC check
|
||||
- Firmware update
|
||||
- Interactive UI
|
||||
- Boot process LED indicators
|
||||
- FS check
|
||||
- Recovery mode
|
||||
|
||||
# OS
|
||||
|
||||
We use FreeRTOS 10.0.1 for sheduling. Documentation available on [freertos.org](https://www.freertos.org/a00106.html).
