Hi Team,
Download on the diamond programr software using the HW-USBN-2B downloader.
1) The normal download can be done using the SSPI SRAM, as shown in the following figure:

2) Error reported using SPI flash download as shown in the following figure:

Question A: As shown in 1), it can be downloaded so it can be confirmed this is not a downloader and wiring issue. When download it using the configuration below it will report error, what might be the possible cause?

B. The customer downloads the FPGA firmware to verify it since their team made a custom board based on the MMCAS-DSP-EVM design files and needs to verify that the firmware is available.
Did TI's FPGA firmware download into nor flash on the FPGA chip via the download method in 2), enabling a one-time download?
Could you help check this case? Thanks.
Best Regards,
Cherry
