Ardiuno+Seed : error compiling Board Generic STM32H7

Hello,
I installed everthing like discribed on your arduino installation guide.
blink and other own programms work with upload to seed.
But this minimal program or other examples (echo…)
#include “DaisyDuino.h”
void setup() {}
void loop() {}
don´t compile: message: error compiling Board Generic STM32H7.
What is going wrong?
I have tried this from another post (copied files to src/utility/DaisySP in documents/adruino…) but it did not help.

in the folder:
docs/arduino/libraries/daisyduino/src/…
there are:
daisy_field.h
daisy_patch.h
dasiy_petal.h
daisy_pod.h
BUT NO
daisy_seed.h

maybe this is the problem - I don´t know
Thanks for help

Hi I think there’s a conflict between STM32Duino Core v2.0 and DaisyDuino v.x.x
Haven’t tried it but a solution may be to downgrade STMDuino core to v1.9
