I can’t find the I2C sensor for the 96Boards Sensors Mezzanine adapter from the RTOS on the Ultra96 board. Am I doing it wrong?
I have an Ultra96 v1 board and a 96boards Sensors Mezzanine adapter. I want to get the value from the sensor on the Sensors Mezzanine adapter via I2C_1 port from Cortex-R5 (xilinx-freertos) on the Ultra96 board. I used the overlay file for Sensors96 for the hardware of the Ultra96 board. (https://github.com/Avnet/Ultra96-PYNQ/tree/master/Ultra96/sensors96b)
In Addition, RTOS uses the iicps driver for I2C communication.
When I use the iicps driver to search for slave addresses on an Ultra96 board, I can always find two values. (0x75,0xF5) However, this address can be detected without the mezzanine board. Also, no signal is output from the I2C_1 port even if communication is started.
