Worked last week, now Fails to compile: ESP32 KeyError: "Invalid board option 'build.cpu'": #4056

drphil3d · 2021-09-15T20:33:18Z

PlatformIO Core.

Configuration

Operating system:
Windows 10
PlatformIO Version (platformio --version):
PlatformIO Core, version 5.2.0

Description of problem

Compile fails on project that's been working flawlessly for the past 8 months. Last week was able to compile just fine, noting has changed in the code base yet this week I get an obscure error that I'm unable to find any relevant documentation or solutions to. I'm getting this error on my other Windows 10 desktop as well. However, I'm able to compile a similar project with the same PIO file without issue.

I've done the regedit fix for python 3.9, didn't help. Uninstalled 3.9, same problem.
I currently have Python 3.7.7

maxgerhardt · 2021-09-16T17:36:20Z

Also noted in https://community.platformio.org/t/precompiled-libraries-error-in-5-2-0/23486/

The platformio\builder\tools\piolib.py tries to access the board.cpu field which many board definitions do not provide, e.g., all the ESP32 ones (https://github.com/platformio/platform-espressif32/blob/v1.10.0/boards/firebeetle32.json#L1-L11)

platformio-core/platformio/builder/tools/piolib.py

Lines 566 to 571 in e6fd766

    
           if self._manifest.get("precompiled") in ("true", "full"): 
        
               # add to LDPATH {build.mcu} folder 
        
               board_config = self.env.BoardConfig() 
        
               self.env.PrependUnique( 
        
                   LIBPATH=os.path.join(self.src_dir, board_config.get("build.cpu")) 
        
               )

This was introduced in a recent commit that was supposed to correctly apply the "precompiled" flags of the library.properties manifest, dce5a39, from 3 days ago in order to fix #3994

CC @ivankravets critical.

maxgerhardt · 2021-09-16T17:44:14Z

A workaround for now is to downgrade PlatformIO to the previous release. In a CLI, type pio system info to find the "Python Executable", then execute a command with that path plus -m pip uninstall platformio, then again with -m pip install -Iv "platformio==5.1.1". But I think this will be fixed rather quickly.

ivankravets · 2021-09-16T17:45:04Z

Please give us a few minutes, we will release 5.2.1.

@maxgerhardt, thanks for the report! 🙏

maxgerhardt · 2021-09-16T18:14:34Z

One thing that may be important when writing the fix is not only defaulting to board.mcu for when board.cpu isn't there (and throwing a nicer error message if that also isn't there), but how the code handles it when the project already uses build_flags to link in the library like in the original issue. Will it work when they are multiple same -l<library> flags in the linker command? Should the code detect that and compensate? Just a few thoughts. Also PlatformIO CI should add a few test cases for test-compiling a project with a precompiled lib for multiple platforms to prevent regressions.

maxgerhardt · 2021-09-16T18:26:41Z

Hmm the fix which now leaves CPU empty if it's not existing is not correct.

platformio-core/platformio/builder/tools/piolib.py

Lines 569 to 571 in 5546932

    
           self.env.PrependUnique( 
        
               LIBPATH=os.path.join(self.src_dir, board_config.get("build.cpu", "")) 
        
           )

E.g., the BSEC library does have an esp32 and esp8266 folder: https://github.com/BoschSensortec/BSEC-Arduino-library/tree/master/src

That fix would just add the source folder of the library to the search path. I'd propse something like

            cpu_arch = board_config.get("build.cpu", board_config.get("build.mcu", ""))
            if cpu_arch == "": 
                pass # error handling
            self.env.PrependUnique(
                LIBPATH=os.path.join(self.src_dir, cpu_arch)
            )

ESP8266 boards also have mcu not cpu: https://github.com/platformio/platform-espressif8266/blob/develop/boards/d1.json

drphil3d · 2021-09-16T18:41:18Z

I added this line to my environment. Didn't fix anything.
board_build.mcu = esp32

maxgerhardt · 2021-09-16T18:43:15Z

That is already there in the board definition, so it won't have any effect. If anything, on the buggy 2.0.0 version, try board_build.cpu = esp32 in the platformio.ini. But dynamic changes may not yet register in that code. Best to wait for an official & released bugfix. (pio upgrade --dev in the CLI)

drphil3d · 2021-09-16T18:46:40Z

sounds good, thank you. I was loosing my mind I'm glad I reported the issue. 🥇

ivankravets · 2021-09-16T19:14:09Z

We tried to follow Arduino's specification https://arduino.github.io/arduino-cli/0.19/library-specification/#precompiled-binaries . However, those guys are strange. MCU & CPU are the same for them. As result, we see a mix of CPU & MCU among the library https://github.com/BoschSensortec/BSEC-Arduino-library/tree/master/src

I've just added a workaround at 369e994 . It should work in all cases. Please re-test with pio upgrade --dev.

maxgerhardt · 2021-09-17T18:19:31Z

Can confirm that PlatformIO now links against precompiled libraries in the example of my original issue with a ARM Cortex-M4 based mkrwifi1010. It also works even when the legacy build_flags with the linker options are included. Also tested an ESP32 with the BSEC library (unmodified) and it works. The nice thing is now that even when I delete the BSEC library's library.json file, it now links correctly, just using the now-respected properties of the library.properties.

freemanr7 · 2021-09-26T15:08:52Z

I'm having similar problems as was presented by drphil3d. I'm having some difficulty understanding how to incorporate your fix into my installation. Based on info below, I think I may have broken something else. Can you recommend how I might get this fixed please? Thanks, Robert

https://docs.platformio.org/page/faq.html#multiple-platformio-cores-in-a-system

You have installed PlatformIO incorrectly, there are multiple cores in your system. Follow the referenced link to get more info. In short, try to uninstall all PlatformIO installations (pip uninstall platformio, pip3 uninstall paltformio, sudo pip3 uninstall platformio, remove <home folder>/.platformio completely) and reinstall it. (Once all cores are removed though, the PlatformIO VSCode plugin will recognize that and try to install PlatformIO again).

freemanr7 · 2021-09-27T11:47:19Z

Thanks very much. I was able to get things restored and get the dev version installed. That took care of the errors tied to this thread. I am still not able to get that BSEC library to link. Not sure if I need to change a setting or flag somewhere. Getting closer :-) Kind regards, Robert

Please edit your previous post to format the output as code using three backticks in Markdown and not just copy-paste the output. I can't see the dependency graph at all in this formatting.

Where does the BSEC library come from? You don't include it via lib_deps as shown here.

When you open a CLI what does pio --version return?

freemanr7 · 2021-09-28T02:51:59Z

@maxgerhardt
Thank you very much for your counsel. I'm not sure I understand your formatting request, but I will work to learn more and do a better job in the future.

The BSEC library is from Bosch. You helped ukarthiksg on https://community.platformio.org/t/bsec-2-0-and-bme688/21813.

pio --version now returns: PlatformIO Core, version 5.2.1b2.

I added

build_flags = -L/Users/robertfreeman/Documents/PlatformIO/Projects/BME688-BSEC2/lib/esp32/ -lalgobsec.a
to the ini file and found some files I had the wrong version and/or in the wrong folders. Seems to be working now. Compiling with no issues.

Warm Regards,

Robert

Okay so you were not talking about BSEC Arduino Library but BSEC2.

But it's still the same story -- no extra build flags are needed for linking to work if you correctly copy the library. When I download the referenced bsec_2-0-6-1_generic_release_04302021.zip file, unpack it, create a new blank project for the ESP32Dev, copy the BSEC_2.0.6.1_Generic_Release_04302021\examples\bsec2 folder into lib/, copy the BSEC_2.0.6.1_Generic_Release_04302021\examples\bsec2\examples\basic_config_state\basic_config_state.ino into src/ and add build_flags = -DLED_BUILTIN=2 (to define the LED -- the sketch needs that) to the platformio.ini, it compiles without problems. The <BSEC Software Library> 2.0.100 is picked up by PlatformIO and the precompiled library from the esp32/ folder is linked in automatically.

That sounds very elegant. I will give it a try. Thanks very much, Robert
