Apologies for reviving this topic, but I faced the same issue.
My ArduinoCore-mbed framework’s version is 4.2.4
I resolved it by following this post.
The includes.txt
file on windows should be at C:\Users\<username>\.platformio\packages\framework-arduino-mbed\variants\PORTENTA_H7_M7
This is my platformio.ini
file
[env:portenta_h7_m7]
platform = ststm32
board = portenta_h7_m7
framework = arduino
lib_deps =
khoih-prog/AsyncMQTT_Generic@^1.8.1
lib_ignore =
STM32Ethernet
STM32duino LwIP
STM32AsyncTCP
