I am migrating our design from the BMI090L to the BMI088. Both part datasheets state an accelerometer noise performance of 160 ug/sqrt(Hz) for X/Y, and 190 ug/sqrt(Hz) for Z. I am observing significantly higher accelerometer noise for the BMI088 as shown in the plots below. The parts are mounted on identical host boards and use the same configuration: GYRO_RANGE_2000_DPS, ACCEL_RANGE_24G, and ACCEL_DATA_SYNC_MODE_400HZ. I am using the latest drivers for both parts. If i remove the line bmi08a_load_config_file(&dev) from the BMI088 set up code then the accelerometer noise performance is improved significantly as shown in the plot below. I suspect there is an issue with the BMI088 driver.
