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: https://docs.espressif.com/projects/esptool/en/latest/esp32/esptool/flasher-stub.html -- Faidon Liambotis Tue Feb 28 03:33:27 2023 +0200
