Buid.link error: bad value

[henriterhofte]

I got a bad value error while during linking firmware.elf after cloning this repo yesterday, doing a 'clean all' and building this repo using Visual Studio Code (v1.74.2), PlatformIO (Core: 6.1.5; Home 3.4.3) and Windoes 11 Education (v21H2). I also get the same error when I change the platform line in platromio.ini to espressif32. Similarly, I also get the same error when compiling the source code in the v2.0.0 release. More details below.

What could be the problem here?

This does not look correct:
framework-arduinoespressif32 @ 0.0.0+sha.caef400

when i update the platformio.ini file to the latest arduino version, this is the output:

Building in release mode

Try deleting the files in the .pio folder, this will let platformio re-download packages

here is my current platformio.ini file for this project:

Short:
Your platformio.ini file (with [platformio] added as a first line) resolves the framework-arduinoespressif32 @ 0.0.0+sha.caef400 error, but now I'm stuck with the missing bootloader error, which was also reported in issue 36.
I even uninstalled and re-installed PlatformIO and Visual Studio Code and updated esptool.py to version 4.4.0, but I got the same result.

In more detail.
Deleting the files in the .pio folder seems to have the same effect as usung the 'Clean All' option in the left PlatformIO menu in VSCode:

 *  Executing task: C:\Users\henrgi\.platformio\penv\Scripts\platformio.exe run --target cleanall --environment release

However, I get the error *** [.pio\build\release\bootloader.bin] Source C:\Users\henrgi.platformio\packages\framework-arduinoespressif32\tools\sdk\esp32\bin\bootloader__80m.elf' not found, needed by target .pio\build\release\bootloader.bin'.

I also tested with esptool.py upgraded to version 4.4.0by including the line directly below in platformio.ini, but the error did not go away:
platform_packages = tool-esptoolpy@~1.40400.0

[henriterhofte]

After running the build command with the --verbose option added, i.e.
C:\Users\henrgi\.platformio\penv\Scripts\platformio.exe run --verbose --environment release
it becoms clear that the FLASH mode option is not used in the toolchain, i.e. the board_build.flash_mode = dio in the file platformio.ini is not used by the toolchain when looking for the proper elf file.
The toolchain seems to depend on python; I am running

and indeed, after copying bootloader_dio_80m.elf to bootloader__80m.elf the error changes to an error in the arguments used for esptool elf2image in the toolchain. Using the --verbose option, I can see that the following the `` -- flash_modeis not followed bydio`, which seems to cause the error

The crucial line is:

[henriterhofte]

The error may be related to this change, committed 2 days ago:
platformio/platform-espressif32@d0835e9

[henriterhofte]

And indeed, changing the line that specifies the platform in platformio.ini to the line below finally allowed me to sucesfully complile and upload the Sensorbox-2 firmware!

platform = https://github.com/platformio/platform-espressif32.git#develop

So, it seems commit specified in platformio/platform-espressif32@d0835e9 that is currently in the develop branch is needed to compile the firmware properly!?

[henriterhofte]

The fix is incorporatedin release v6.0.0 of the espressif32 platform

So, after pulling v6.0.0 from GitHub, in platform.ini for the platfrm line, you can now simply use the line
platform = espressif32

and then the issue is gone.

[mstegen]

Thanks for debugging this issue.
Just tried a fresh installation of Ubuntu + VScode + PlatformIO, and i ran into the same issue where the bootloader could not be found.

platform = espressif32 did not work for me.
Somehow it did not install the latest version, but instead installed framework-arduinoespressif32 @ 2.0.6 weird...

platform = espressif32 @ 6.0.0

did install the correct platform, framework and esptool
