Problem selecting image to run using configsel pin on Max10.

I have been working with the simple LED Binary and KnightRider example for the I2C RSU slave example on the 10m08sae144eval board. I have built each project using dual compressed image setting and then used the convert programming files utility in Quartus 17 to combine the .sof files into a .pof file with one of the project's sof files directed to be in cfm0 and the other in cfm1. I then load the pof into ​the eval board using a byte blaster. The result is that whichever project is loaded into cfm1 is the one that runs, no matter what setting I put on switch 6 ( that controls the logic level on the bootsel (configsel) pin). I have verified the switch signal is getting through to pin 126 correctly on the max10. If I erase cfm1 then it falls back to running the image in cfm0. I must have a wrong setting somewhere???? Any help would be appreciated.

Hi,

 

  1. Check the  Option/Boot Info and the ICB setting dialog box. The ICB setting dialog box allows you to set the following:
  • User I/Os weak pull up during configuration.
    • Configure device from CFM0 only.
    • Note: When you disable this feature, the device will always load the configuration image 0 without sampling the physical CONFIG_SEL pin. After successfully load the configuration image 0, you can switch between configuration image using the config_sel_overwrite bit of the input register. Refer to related information for details about Altera Dual Configuration IP core input register.

For more information refer below link.
