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 can successfully read back FLASH_RD_RDID. I got value 20h.

But when I tried to read back DEVICE_ID_DATA_x value, all give me value 00h .

Thank you,

Remya

Hi Remya,

The default value of DEVICE_ID_DATA_x is 0x00.

Thus, it is expected behavior.

Below is my Cyclone 10 LP DEVICE_ID_DATA_x:

Thanks
