custom device driver block not supported for esp32

I have created a custom device driver block accoding to link Create Custom Device Driver Block for Arduino Library - MATLAB & Simulink - MathWorks 中国. While this block is used in my model, Simulink(build or generate code) alway output "unsolved name codertarget.arduinobase.board.ESP32-WROOM(ArduinoCompatible)Board". So, the question is whether "custom device driver block" is supported for esp32.

Thanks & Best Regargs

https://www.mathworks.com/help/supportpkg/arduino/ug/add-custom-esp32-arduino-compatible-boards-to-support-package.html certainly suggests ESP32 WROOM and ESP32 WROVER are supported at the very least.

that's true. If i only add some built-in blocks（eg: WIFI、PWM..）to my model, then building or deploy to HW,everything works well. When a "customed device driver block" added to my model, the error message appeared.

in addition, i debug the process of building, the message appeared when Executing the expression “arduino.supportpkg.getBoardInfo”。arduino.supportpkg has methods like getSAMLibraryROot、 getAVRRoot...

getESPxxx not found. maybe that's the point ?

my simulink version is 2022a, it seems that this version has no option "Create Custom board" like your link

thanks

It apears that documentation page is new as of R2022b, https://www.mathworks.com/help/releases/R2022b/supportpkg/arduino/ug/add-custom-esp32-arduino-compatible-boards-to-support-package.html which implies that potentially the support was added in R2022b.

Maybe worth a try
