Please look at the website and manual for more information about how to flash.

Please make sure to download the firmware matching your board from these locations:

• latest (latest development version)

Firmware files are named as follow:

• YaSolR-<VERSION>-oss--<BOARD>.bin: for the firmware used to update
• YaSolR-<VERSION>-oss-<BOARD>.factory.bin: for the firmware used to flash for the first time or to do a factory reset

Where:

• VERSION: YaS☀️lR version, or main for the latest development build
• BOARD: the board name, from the list of Compatible ESP32 boards

Images ending with -debug are for development purpose or to troubleshoot issues: they are not optimized and output a lot of debug logs.

• .github: CI/CD workflows
• data: Build components added to the firmware
• include: Firmware include code
• lib: Firmware libraries
• pio: pio scripts
• src: Firmware source code
• test: Firmware tests
• tools: Some random tools
• partitions.csv: ESP32 custom partition table
• platformio_override.ini.template (to copy to platformio_override.ini): PlatformIO configuration override
• platformio.ini: PlatformIO configuration

1. Configure platformio_override.ini to your needs (you can copy the template file platformio_override.ini.template to platformio_override.ini for that)

2. Build the file system and the firmware:

pio run -t build

First time, flash the entire firmware which includes the partition table and all partitions:

esptool.py --port /dev/ttyUSB0 \
  --chip esp32 \
  --before default_reset \
  --after hard_reset \
  write_flash \
  --flash_mode dout \
  --flash_freq 40m \
  --flash_size detect \
  0x0 YaSolR-VERSION-MODEL-CHIP.factory.bin

Next time, just upload the partition you modify

pio run -t upload
pio run -t monitor
