To use the ASMI Parallel II Intel FPGA IP for reading and writing data to external flash devices, you need to follow these steps:
1. Connect the IP to the Avalon memory-mapped interface of your FPGA design.
2. Use the Avalon memory-mapped interface to access the control status register (CSR) for other operations.
3. Translate the generic commands from the Avalon memory-mapped interface into device command codes.
4. Use the Avalon memory-mapped interface to perform direct flash access (write/read) through the IP.
5. Set the clock frequency to lower or equal to 50 MHz.
6. Hold the signal for at least one clock cycle to reset the IP.
7. Make sure you are using the supported configuration devices (EPCQ, EPCQ-L, and EPCQ-A). If you are using third-party flash devices, you need to use the Generic Serial Flash Interface Intel FPGA IP.
8. Ensure that you are using the Intel Quartus Prime software version 17.0 or later.
