When you realize the AVSTx8/AVSTx16/AVSTx32 configuration scheme using Parallel Flash Loader II IP, you might need to generate the pof file for flash programming.
If the configuration device you choose is QSPI flash, you will encounter the error message "Configuration device xxxx cannot be used with selected programming mode" during the pof generation.
In the setting of configuration device, choose the CFI flash which has the same density to the target QSPI flash. The resulting pof file can be used to program either a CFI flash or QSPI flash of that density.
