Honored ContributorHi Dave,
Thanks for the quick response. I believe you are talking about Manufacturing ID (0x20) and Device ID (0xBA). They are all the same for all N25Q devices including the 64M and 1G devices. The only difference is Memory Capacity ID(0x17 for 64M and 0x21 for 1G part). Also the 1G part support all 64M part commands(OPCODEs) for backward compatibility. I've checked with scope the what the FPGA reads from the SPI on boot and I can see that the data in both cases (64M and 1G) is read correctly (at least first several bytes that are different form 0xFF). I can try to capture more using LA, but it is going to take time. About the idea to disable ID check - I'm not sure how to do that. The file conversion tool does not work for generating rbf files for active serial mode. I found that the hard way after couple of days of trying - the only way I know to get a good rbf file is to set the rbf file to be automatically generated with the sof file in the device configuration options. Is there another way to disable ID check and get good rbf file for active serial mode? Are you sure the ID check option is for the FPGA boot or for the JTAG debugger when programs the jic file? Thanks again, Krassimir
