Hi,
I am testing the AD-FMCLIDAR1-EBZ on Altera Arria 10 Soc Dev Kit by using the latest Linux image (2019_R1-2020_02_04.img).
The DK was able to boot up and detect the chips on the DAQ board (AD9094 and AD9528). However it is failed to detect the chips on the AFE board (AD5627 and AD7091).
Note:
1. 7 resistor are modified that mentioned the master branch of the hdl page.
2. The AFE board was connected to P1 and then P2 of the DAQ board. Still, nothing is detected.
3. I used a oscilloscope to probe the I2C and the SPI of the AFE board, no signal whatsoever.
So here are my questions
1. Is there any special settings on the Altera DK? I am using the default jumper/DIP settings
2. Is there any way to dump I2C/SPI message to the AD5627 or AD7091 using the serial console?
Below are the boot logs FYR.
Any help is appreciated. Thank you very much.
