FPGA cannot be configured although VIVADO says the bin file has been successfully downloaded into the SPI FLASH(S25FL128SAGBHIA00). I'm not sure if there's something wrong in the schematic. Can someone take a look at my schematic?
Besides, the power of Bank14 is 2.5V. FLASH_CCLK is connected to CCLK_0 pin (E8) in BANK0.And the FPGA chip is XC7A15T-1FTG256C.
Any advice is appreciated. Thank you in advance.
Can you hook up a logic analyzer to capture waveforms upon FPGA POR? That way, you can verify if the bitstream data can be read properly from the Flash. You are welcome to post the waveforms here and we can take a look at them.
