Do you still having issue with accessing I2C using M4? If yes, I'll look into this and get back to you. I have done some codes to access the DPS310 Pressure sensor on board QuickFeather.

Yes, I cannot seem to get any communication to start on the wishbone bus, so any example that you have would be much appreciated. I am likely giving a talk on this platform at our NuttX workshop in a couple weeks and would really like to demonstrate some of these features.

The QORC-SDK has included new application for QuickFeather that include example for adding I2C sensor to the device. Please check it out. Application "qf_mqttsn_ai_app" is using I2C for accessing QuickFeather on-board I2C sensor.
