Arria 10 will not load from Micron MT25QU256 PROM

Hi Nooraini,

I have already programmed the MT25QU with the .jic file using my USB Blaster. I selected the MT25QU256 as the programming device in the Quartus programming device options and as the target device in the file conversion program. I am using the device in ASx1 mode. The PROM programs fine. It just fails to load the FPGA at power-up.

What I am seeing at power-up is that the A10 reads the PROM status register, reads the device ID registers and then begins a fast read opeation from the PROM. It read about 33 bytes then during the 34th byte the CS to the prom is terminated after 7 bits. Please refer to the scope images in my original post to see the SPI bus transactions.

Can I really use a Micron MT25QU256 device with an Arria10 or do I need to use a MT25QU512 as indicated in some cross reference chart I saw.

Regards,
