I running with SSP 1.5.1 which has busy detection in the list of update, but the riic driver doesn't seem to be detecting, or reporting, busy.
I'm connecting two S5D9s to an i2c bus with multiple device and the devices are failing to respond when both masters are on the bus.
If busy is detected, how is it being reported? As a non-zero return code from the read or write, or in the call back?
