    Hi, for CRC error, i think it could be due to the incorrect bitstream / bitstream order when loading it into the QSPI flash. I would suggest to select the appropriate data format when generating RPD file. You can select little endian for it. Otherwise, you need to do bit reversal.

hi how can we read back flash besides flash controller IP, is there any utility or method to read a FLASH via FPGA using jtag or serial interface.

thanks & regards!
