Problem with MAX 10 pin assignment

[Altera_Forum]

Hi all, 

I'm currently using the MAX 10 (10M02SCU169A7G) for one our project. In MAX 10 (10M0) fpga the pin C4 and C5 are nSTATUS and CONFIG_DONE respectively. And we have used this pin for some other purpose also. As per the datasheet both these pins are dual purpose pins. When i do the I/O Assignment analysis i am getting the following errors.  Error (176310): Can't place multiple pins assigned to pin location Pin_C4 (IOPAD_X3_Y7_N14)  Info (176311): Pin MR is assigned to pin location Pin_C4 (IOPAD_X3_Y7_N14)  Info (176311): Pin ~ALTERA_nSTATUS~ is assigned to pin location Pin_C4 (IOPAD_X3_Y7_N14)  In some forums giving solutions like "change the settings of dual purpose pins in the quartus software" but i am not able do this because the window for this settings in quartus software is grayed out (Attaching the screenshot) https://alteraforum.com/forum/attachment.php?attachmentid=14700&stc=1   Is there any other way i can avoid this error?...

Hi, 

 To use the configuration and JTAG pins as user I/O in user mode, you must do the following in the Quartus Prime software: 1. On the Assignments menu, click Device. 2. Click Device and Pin Options. 3. Select the General tab of Device and Pin Options. 4. In the General Options list, do the following: • Check the Enable JTAG pin sharing. • Uncheck the Enable nCONFIG, nSTATUS, and CONF_DONE pins.  https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/hb/max-10/m10_handbook.pdfPage No 496 https://www.alteraforum.com/forum/attachment.php?attachmentid=14811   Best Regards, Anand Raj Shankar (This message was posted on behalf of Intel Corporation)
