Programming pof-file ignores attached isp-file

Hello,

I try to programm the flash of a MAX10SAU324 on a customer board. In the Programmer GUI I attached and activated a isp-file to set all used I/O pins to tri-state mode. But the isp-file seems to be ignored as long as all I/O pins are defined as tri-state and the pins seem to be pulled down during programming. If I change at least one pin to an other mode than tri-state it works fine.

Additionaly I tried to safe the pof file in the programmer GUI and tired to include the isp-file information to the pof-file by activating the checkbox. But the pof-file remains unchanged. This also seems to be buggy.

I hope anyone can confirm these bugs or help me if I did something wrong.

Regards

Dennis

    Hi Dennis,

    In Quartus setting, did you set the "Reserve all unused pins" option to "As input tri-stated with weak pull-up"

    Assignment -> Device -> Device and Pin Options -> Unused Pins -> Reserve all unused pins

    Thanks.😉

      Hi,

      thank you for your answer.

      I did set the "Reserve all unused pins" option to "As input tri-stated with weak pull up". I also tried to change this option to "As input tri-state" but there was no difference in behavior.

      I also do not think that there are any problems with unused pins. The problem is, that all used pins are driven low during programming even though I defined them to be tri-state in the isp-file.

      I can see that the isp-file is beeing ignored because the progress bar runs only once.

      If I change only one pin in the isp-file to any other state than tri-state everything works fine, the progress bar runs twice (because of the two files, isp and pof) and all pins are tri-state during programming expect the changed one.

      Do you or anyone else have any other suggestions?

      Regards

      Dennis
