esptool for Debian
------------------

The package does not currently ship the binary flasher stub code for the Xtensa
ESP32 chips (ESP32, ESP32-S2 and ESP32-S3), as there is no compiler and libc
for this architecture present in Debian. As a result, several esptool features,
such as higher baud rates, or erasing flash contents, will not work on these
chips. Note that stubs are shipped for the confusingly similarly named RISC-V
ESP32 chips, such as the ESP32-C2, ESP32-C3, ESP32-C6, ESP32-H2 (as well as the
ESP8266), however.

The upstream project ships precompiled binaries using Espressif's proprietary
toolchain and SDK (ESP-IDF) for all chips, which however cannot be shipped in
Debian "main" due to the Debian Free Software Guidelines.

For more information about the flasher_stub, please refer to the upstream
esptool documentation:
