New ContributorArria 10 will not load from Micron MT25QU256 PROM
I am using an MT25QU256 PROM to program an Arria 10 10AX027E4 device. The MSEL setting is active serial standard power on (011). The programming voltage is 1.8V. It appears that the access to the PROM starts normally then terminates early. I have attached scope shots of the transactions between the FPGA and the PROM. One thing I see is that the FPGA de-asserts the select and stops the clock just before reading the last bit of a byte.
I have followed all the recommendations for using the MT25Q devices. I believe that the file is compressed.
Can somebody explain what I'm seeing and how to fix it?

Hi JCass5,
Since you mentioned that you are able to program the Arria 10 with a .sof file, I assume that you are able to use Quartus programmer and a download cable (such as USB Blaster) to program the Arria 10 via JTAG interface. Are you able to program the MT25QU flash device with a .jic file using Quartus programmer? The Quartus Prime v18.1 should have the option to allow users to generate the .jic file for MT25QU for Active Serial configuration. Thus you can test the MT25QU with the standard programming process using Quartus programmer and .jic file. If the Active Serial configuration is successful after programming MT25QU with the .jic file, this indicates no hardware or signal connection issue.

JCass5I have verified that the control signals are working properly and I have changed from a compressed file to uncompressed.
Also with the processor disable I can load the FPGA with the SOF file. I am keeping the processor disabled while trying to load from the PROM so there is no chance of interference.
