No transmitted data via i2c

Hello together,

it seems that the i2c bus of the SKR 2 Rev B is not functional in combination with the "EXPERIMENTAL_I2CBUS" feature of Marlin (Version 02000901). I used a 24MHz Logic Analyzer (5MS/s and 2Mhz with pulseview) but could not record any signals.

same setup with my older SKR 1.4 worked fine.

I noticed that the SKR 2 now has a capacitor between GND and 5V VCC which the SKR 1.4 did not have.

Since in the near future SKR 1.4 probably won't be produced anymore, it would be good if that feature works.

Maybe someone has any suggestions how to solve the issue

greetings 2MSL
