Having a strange problem with framework-arduinoespressif32 version 3.20003.0 (2.0.3). It seems the bootloader path can no longer be found when uploading a newly built firmware to a esp-wrover-kit:

esptool write_flash: error: argument <address> <filename>: [Errno 2] No such file or directory: 'C:\\Users\\x\\.platformio\\packages\\framework-arduinoespressif32\\tools\\sdk\\esp32\\bin\\bootloader__40m.bin'

Right away it looks as though the “dio” is missing from the filename. I checked boards.txt and see build.boot is being set, and also tried adding build_board_boot=dio to my platformio.ini and do not see it trickling down to the esptool call.

I noticed platformio-build-esp32.py in /.platformio/packages/framework-arduinoespressif32/tools has some new logic that might be causing the issue:

def get_bootloader_image(variants_dir):
    variant_bootloader = join(
        variants_dir, env.BoardConfig().get("build.variant", ""), "bootloader.bin"
    )
    return (
        variant_bootloader
        if isfile(variant_bootloader)
        else join(
            FRAMEWORK_DIR,
            "tools",
            "sdk",
            "esp32",
            "bin",
            "bootloader_${__get_board_boot_mode(__env__)}_${__get_board_f_flash(__env__)}.bin",
        )
    )

whereas versions prior to 3.20003 do not use this method and instead use:

    FLASH_EXTRA_IMAGES=[
        ("0x1000", join(FRAMEWORK_DIR, "tools", "sdk", "esp32", "bin", "bootloader_${BOARD_FLASH_MODE}_${__get_board_f_flash(__env__)}.bin")),
        ("0x8000", join(env.subst("$BUILD_DIR"), "partitions.bin")),
        ("0xe000", join(FRAMEWORK_DIR, "tools", "partitions", "boot_app0.bin"))
    ]

which works.

I also noticed platformio-build-esp32.py doesn’t match the sources in github nor could I find any references to “__get_board_boot_mode” in github, causing some further head scratching.

Unfortunately I actually need this newer version as it fixes a problem with tls handshake timeouts when reconnecting, but the bootloader image file name is not being constructed as expected. I’ve also reviewed the platform migration notes for 5 to 6 but don’t see an obvious issue related to that.

Any clues as to what I’m missing?

Thanks!
