I am trying to program the ttgov2 board using platformIO on windows 10.
Compilation seems to be ok, but I have the impression that there is no upload (although there is no error message): the board keeps runnning the same code (that it was probably programmed with by the supplier)
I checked the device manager and the board shows up on COM7
When ik start debug (F5) I get the following:

Thanks for the fast answer.
I tried: Terminal â Run Task â PlatformIO â PlatformIO: upload
But the first time, I got a âtimed outâ error (see below)
The upload is ok though, when I use the reset button at the moment that the tool tries to upload.
Is that the normal procedure, or can de bootloader be activated over USB?
The auto-reset circuitry is board-design dependent, some boards require the âflash buttonâ (GPIO0) to be held down, then a reset push, then release of the flash button. So it may okay that some require it and some donât. I donât know the specifics of the TTGOv2 Paxcounter board, but Iâm sure the schematics are available to be looked at somewhere to figure that out whether it just has buttons or an on-board usb-uart adapter with RTS and DTR connected via 2 transistors to EN and GPIO0.
The usb-uart adapter on the board indeed has RTS and DTS connected to RST/EN and IO0 using transistors.
Even so, when I use the Terminal â Run Task â PlatformIO â PlatformIO: upload task, the upload times out if I donât manually reset the chip at the right time.
Do I have to add something to the task, or use another one to use the RTS/DTR lines of the UART to do the reset for me?
With this firmware, I first got an error, saying it didnât know the board, so I downloaded the ttgo-lora32-v21.json file and put it in the expressif32/boards directory.
After that, it starts to compile, but I get âfatal error: pins_arduino.h: No such file or directoryâ
No thatâs not fully how to add a ânewâ board (variant folder in framework-arduinoespressif32 missing), but the point is that that should never be needed. platform-espressif32 should have the board if its properly updated. The project compiles fine for me with the ttgo-lora32-v21.json file after selecting the board in in the platformio.iniâs default_envs and removing the _example filename part of the LoRa keys.

Please remove all <home folder>/.platformio/platforms/espressif32* and <home folder>/.platformio/.cache rebuild the project to get a clean download again.
I did as you asked (deleted both dirs, got a clean install from git and renamed the keys_example file.
Now, I donât get the âboard not foundâ message any more, but I still get the âpins_arduino,h: No such file or directoryâ error (see below)
Under âPROBLEMSâ there are also some messages that might be related:

Something is really wrong here, that platform version is ancient, it should be 4.2.0 (see here) with framework-arduinoespressif32 being 2.0.2. But the project just declares that the regular platform version is to be used.
Can you cleanly redownload the project again and do
I remember now that I have used platformIO a few (5?) years ago under atom on this PC, and it seems that this installation still exists.
This might be the cause of the problems.
What is the best way to remove both installations of platformIO and reinstall it under VSC only?
Remove the PlatformIO extension from both Atom and VSCode, then remove the C:\Users\<user>\.platformio folder completely. Restart VSCode, add back the PlatformIO extension and let the installation complete + restart VSCode. Then try building the project again.
