Hi Mark,

Thanks for bearing with us. It seems like the Windows environment variable IDF_TARGET is being set to "esp32" somewhere. We don't have any explanation for why this has happened, though. Setting this environment variable is not required to use ESP-IDF, but it is optional to automatically override the selected target (which is why you keep getting these errors - there's a conflict between the "overridden" value in the environment variable and the target you're asking to build).

If you open a clean cmd window and then immediately run "echo %IDF_TARGET%" (before running export.bat or anything else), do you still see esp32?
If you "edit system environment variables" and check the list of environment variables for both the system and your user (both lists are in the same window), then do you see IDF_TARGET in the list anywhere? If it's there, please delete it.
If that doesn't lead anywhere, could you please post the output of "idf.py version" (after running export.bat)?

Thanks again for your patience.

When I echo %IDF_TARGET% in a clean CMD window, it does report esp32. I'm pretty sure that I didn't set that myself but it was easy to fix.

After changing the environment through Windows "Advanced System Settings", closing the old CMD window, and opening another, project building works as documented without having to change the IDF_TARGET variable.

Everything seems to be pretty good now.

Thank you Angus!

I'm running into this same issue on MacOS and haven't been able to solve it. I can't set the target to esp32. I get the same error message:

Code: Select all

What do I need to change to avoid this error? I've tried following the steps in this thread, but they don't seem to change anything.

Possibly your IDF_TARGET variable is set to something. Can you do an 'echo $IDF_TARGET' and post what it says?

all of a sudden I'm getting this error too. I opened a the touch_pad_interrupt example in vscode on ubuntu 21.10

Version: 1.63.2
Commit: 899d46d82c4c95423fb7e10e68eba52050e30ba3

but even after selecting esp32s2 as a target, i get:

Code: Select all

IDF_TARGET in CMake cache does not match IDF_TARGET environment variable

. At first, after selecting esp32s2, the entry would change. After restarting vscode, it no longer changes either, and I still get the error. when I go to the integrated bash terminal or open any external terminal and type

Code: Select all

echo $IDF_TARGET

all I get is an empty line.

I found out it's only regarding the esp-idf terminal window in vscode. When I open a regular terminal and run an export.sh from esp/esp-idf directory, the conversion to another chip works fine.

@ESP_Angus

Hello. I have come across this post and I thought I would ask for help. I am trying to set the esp-idf target via the ESP-IDF terminal but it does not work! I cannot wrap my head around this issue and its driving me nuts:
