How to fix PlatformIO No such file or directory bootloader__80m.bin/bootloader__40m.bin

Problem:

While trying to upload/flash an ESP32(S2/S3) project using PlatformIO with a platformio.ini like this:

platformio.ini
[env:esp32-s2-saola-1]
platform = espressif32
board = esp32-s2-saola-1
framework = arduino

you see an error message like

platformio_bootloader_missing.txt
esptool write_flash: error: argument <address> <filename>: [Errno 2] No such file or directory: '/home/uli/.platformio/packages/framework-arduinoespressif32/tools/sdk/esp32s2/bin/bootloader__80m.bin'
*** [upload] Error 2

or

platformio_bootloader_missing_esp32.txt
esptool write_flash: error: argument <address> <filename>: [Errno 2] No such file or directory: '/home/uli/.platformio/packages/framework-arduinoespressif32/tools/sdk/esp32/bin/bootloader__40m.bin'

Solution

This is a bug in version 2.0.4 of the arduino-espressif32 framework. In order to work around it, use version 2.0.3 until this bux is fixed. You can do this by appending

platformio.ini
platform_packages = framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32.git#2.0.3

to platformio.ini. Full example:

platformio.ini
[env:esp32dev]
platform = espressif32
platform_packages = framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32.git#2.0.3
board = esp32dev
framework = arduino
