Hi, I am trying to read flash device ID from our Arria 10 SoC based board. (Flash device is EPCQL512). I have used Intel FPGA Serial Flash Controller 2 and clock used for IPcore is10 MHz.

After setting read enable=1 , I am getting csr_rdata_valid =1. But the data corresponding to csr_rdata_valid high is “10000000”. I have attached screenshot of data captured in Signal Tap Logic Analyz...

Hi Wolfgang,

I have attached the source code used for reading Device ID. I didn't used the NIOS or System console. I captured the signal in Signal Tap Analyzer and from there I got the value "10000000".

Also I couldn't find the exact data sheet for serial controller 2 . Can share me if you have?

Thank you,

Remya
