Error (176310): Can't place multiple pins - JTAG Sharing

Hello,

I followed all the rules in https://www.altera.com/en_us/pdfs/literature/hb/max-10/ug_m10_config.pdf

  • Check the Enable JTAG pin sharing.

  • Uncheck the Enable nCONFIG, nSTATUS, and CONF_DONE pins.

to enable JTAG pin sharing. But when I try to actually use them, say, PIN_16(TMS) I get

Error (176310): Can't place multiple pins assigned to pin location Pin_16 (IOPAD_X10_Y17_N14)

Info (176311): Pin J1_5 is assigned to pin location Pin_16 (IOPAD_X10_Y17_N14)

Info (176311): Pin altera_reserved_tms is assigned to pin location Pin_16 (IOPAD_X10_Y17_N14)

Any help would be greatly appreciated.

    I found the problem - it won't allow dual-use whilst signalTap is enabled.

    Additional info: The config scheme is "Internal Configuration" and the "Dual-purpose Pins" tab is empty.

    Thanks for your reply Alex, but this is actually duplicate information from the Configuration Guide and I did not specify any JTAG pins before anyway. I removed a couple SDCs but no joy. I notice in the pin planner that the JTAG and my mission-mode IO are both present and mine are assigned to the actual physical pins. Tried deleting the JTAG - no joy.
