BMI088 problems with interrupt with 400kHz I2C

[aswang]

Hello,

I am able to read data using INT1 from the accelerometer at 800Hz with 100kHz I2C clock frequency. However, when I increase my I2C to 400kHz, INT1 only fires at 100Hz. The gyroscope is not affected (1kHz for both I2C speeds). Do you have any ideas?

This is with the Adafruit Metro M4 and Arduino IDE.

Thank you very much!

Please confirm with a logic analyzer whether this is an issue with the sensor (Interrupt not firing) or the MCU (Interrupt not serviced). My understanding is that the latter case is most common.
