Hello,

I have an ESP 32 WROOM and would like to get its internal LED to flash.

When compiling, I get the following error message:

Hallo HansJuergen

Did you install the ESP toolchain?

More infos here:

https://flowcode.co.uk/wiki/index.php?t ... _Toolchain

I have installed the ESP toolchain. The folder is approximately 2.23 GB in size.

Hello.
Your project compiles for me OK
Have you completed a full component database update?
Help > Library Updates...
Change Files in-use to Full database

What path have you got for the ESP32 location?
File > Global Settings.. > Locations Tab

Finally can you try deleting C:\FC_ESP\mtxesp32s_sdkconfig

Then compile your project again.

Hello,

Unfortunately, the proposed measures have not been successful.

Have you completed a full component database update
I have performed all updates.


What path have you got for the ESP32 location?
The storage locations is: C:\Program Files (x86)\Flowcode v10\FC_ESP\.
The folder was entered by the system as follows.


deleting C:\FC_ESP\mtxesp32s_sdkconfig
I deleted the mtxesp32s_sdkconfig folder.

That is your issue.
C:\Program Files (x86) requires elevation which you won't get, hence the errors you are seeing.
The correct default location is on the C root drive.
Can you delete the ESP32 toolchain and reinstall to the default C drive i.e. C:\FC_ESP
Restart your project and make sure the path for ESP32 is also correct within File > Global Settings.. > Locations Tab
