Quartus Prime not allowing apparently correct I/O assignment

Hi, I'm using Quartus Prime 15.1 and trying to program the DECA evaluation board. I've used a file provided by them to do the pin assignments. I am completely sure that I have used the correct one. When I compile, the Analysis and Synthesis runs just fine. However, the fitter keeps giving the following errors:

Error (169235): I/O bank 8 cannot select VCCIO of 1.2V which is required for pin LED[0] with I/O standard 1.2

Error (169193): VCCIO 1.2V is not compatible with the VCCIO requirement of the I/O bank 8 imposed by the selected configuration scheme

It shows the same thing for LED[1] which I am also using, which connects to a green LED on the board. One possible lead: the device that I select is 10M50DAF484C6GES, but I keep getting the following message: Info (253020): Default device 10M08DAF484C8G is automatically selected for the device family MAX 10. This message displays as soon as the device is selected when creating a new project.

Can anyone explain why this might be happening? Thanks!

Edit: never mind about that default device message, that comes when I select the MAX 10 family prior to selecting the specific device

    This means you have an incompatible set of I/O standards connected to bank 8. You need to consider what other I/O is connected to bank I/O and ensure they are all 1.2V I/O standards.

    I appreciate you state you've used a set of pin assignments provided by Arrow. However, there is clearly something wrong with it - these example files have been known to be wrong in the past. Post your project's .qsf file here and we can have a look.

    Cheers,

    Hi a_x_h_75,

    so i can use different standards as long as they are all signed with the same VCCIO, right?

    Yes. You can use different I/O standards as long as they're all 1.2V.

    Cheers,

    Hi all,

    I have encountered the same error today. I should start out by saying that Arrow's Tcl script works as intended, there is an additional important step in the tutorial I was following.

    For your config file to match the hardware of the DECA board you have to change a few more options.

    Go To: Assignments -> Device -> Device and Pin Options -> General

    There UNTICK "Enable nCONFIG, NSTATUS, and CONF_DONE pins"

    This will allow you to set the bank 8 I/Os to 1,2V.

    For the DECA board you should also UNTICK the rest of the config options int the same window:

    Auto-restart configuration after error

    Release clears before tri-states

    Enable device-wide reset (DEV_CLRn)

    Enable device-wide output enable (DEV_OE)

    Enable nCONFIG, nSTATUS, and CONF_DONE pins

    Enable JTAG pin sharing

    Enable CONFIG_SEL pin

    Leave "Auto usercode" enabled
