Help Needed: Implementing UART and SPI on Altera MAX II EPM240 CPLD

Hi everyone, I'm currently working with the Altera MAX II EPM240T100C5N CPLD and I'm trying to implement UART and SPI communication protocols on it. I'm using Verilog HDL and targeting a 3.3V logic ...

Hi,


Forgot to mention that you need to change device under Device tab.

    Hi, @ShengN_Intel .

    I attempted to open the CV_SOC_UART_project using Quartus Prime Standard Edition 18.0. I selected the uart.qpf project file and changed the target device to MAX II EPM240T100C5N. However, when I tried to compile the project, I encountered the following error:

    Error (12252): Uart.OCRAM: Selected device family does not support this module.

    I also tried to change the device family, but it still lists the MAX II device. Why is this happening? How can I implement UART functionality on the MAX II series?

    Is there an alternative method for UART communication on MAX II devices, or is the MAX II no longer supported for such functionality?

    I would really appreciate your guidance. Looking forward to your positive response.
