I'm a fresh user trying to get acquainted with FPGA/ZYNQ programming. I wanted to translate the csi rx example project desgined for zcu102 to my zcu104.
In the xmipi_example program, i already changed the external clock generator to the 8T49N24 on zcu104 instead of the Si5324 on zcu102. And I can got the hdmi output and saw the colorbar produced by the program itself on the monitor.
However, i counldn't set up the imx274 camera sensor because the program stuck in sending data to the sensor through iic.
Sending data through iic didn't call the callback function and the transmitcomplete flag remained 1.
I have not made any changes to the program except using the 8T49N24 instead of the Si5324.

Could you please check your IIC clock and data lines on your board ?
Are they pull-up at "1" when there is no transaction occurs ?
Can you show me the oscilloscope waveform capture of your IIC lines ?

Thank you for your reply.
I got the waveform from ila.
They pull-up at "1" all the time and didn't have any change when the transaction occured.

You might want to add a trigger to your ILA on a falling edge. Else, if you just try to capture randomly, you will probably not see anything happening.
You might want to check my Video Series 31 – Debugging a Video System using an ILA for the basics of using an ILA.
