I am trying to get the WiFi demo project to run on an ESP32 board ( https://heltec.org/project/wifi-kit-32/ ) I am finally able to make the model build and compile for the ESP32, but I don't think it is working.
On the Serial Monitor I expect to see the results from the GET request, but all I see is some startup messages and what looks like an error to do with the crystal frequency.

It says that the crystal frequency is set to 40Mhz, while the crystal that is actually on my device is in fact 26Mhz. I can't work out how to change the config for the crystal frequency in the "Waijung 2 Target Setup" block.
Is there somewhere that this can be configured?
( I think the relevant settings are automatically put into sdkconfg.h , but i do not know where in the simulink code generation process this is done)
