Hello, I am struggling with the SDP platform for ADAR1000 . We controls the ADAR by using SPI interface from FPGA to ADARs but unfortunately, when we write the data to the ADAR1000's registers by using P3 PMOD connector we could not read the same datas by using SDP platform the were not set. We just want to test the SPI whether write the correct data or not but we could not see the same data by using SDP platform.
Also, when we write the data ADAR1000's registers by using P3 connectors, we could not see the SCLK or CSB on the oscilloscope by using P6 connector which is digital interface connector. We wanted to see the SPI signals which are SCLK SDIO and SDO via P6 connector. Aren't these connectors connected to each other? because there are also same pins SCLK SDIO and SDO.
Can you suggest any idea with these issues.
P3 isn't directly connected to P6. The signals are separated by a few level translators. If you aren't getting any signals on the P6 connector, that means something is wrong, probably with the level translators.
Thank you for your supporting.
