# Reflashing

Ideally you build the code and flash, but that will be your code signing.

You can also flash these binaries.

You need `esptool`

## esptool

`esptool.py -p /dev/ttyUSB0 write_flash 0x1000 Faikin-S1-PICO-bootloader.bin 0x8000 partition-table.bin 0xd000 ota_data_initial.bin 0x10000 Faikin-S1-PICO.bin`

- The `Faikin-S1-PICO-bootloader.bin` needs to be the relevant release bootloader binary file for the chip used.
- The `Faikin-S1-PICO.bin` needs to be the relevant release binary file for the chip used.
- The bootloader address differs between ESP32 versions S1 and S3. For the S1 versions the bootloader is located at 0x1000. For the S3 models this needs to be changed to 0x0.

## 8266 port

The ESP8266 port is maintained by Pavel Fedin; project URL is: https://github.com/Sonic-Amiga/ESP8266-Faikin .
Since this is a backport; it may lack some features of the newest ESP32 version. Please contact the author for any questions.

Flashing command (addresses differ from ESP32 !!!)

`esptool.py -p COM3 -b 460800 --after hard_reset write_flash --flash_mode dio --flash_freq 40m --flash_size 8MB 0x8000 partition-table-8266.bin 0xd000 ota_data_initial-8266.bin 0x0 Faikin-8266-bootloader.bin 0x10000 Faikin-8266.bin`
