Configuration Issues

Hi,

My current project is on the ACEX1k and my problem is that when I configure using my byte blaster cable, all works well but when I try configure using the ECP1C8, the logic is no longer correct. I also notice that a typical output pin frequency doubles when using the EPC1. The EPC1 configure done signal goes HI so it passes configuration.

My older projects on the ACEX1K still works normally.

Attached is my project for your perusal.

Thanks for any help.

Vic

    Hi,

    I just checked up your Device & Pin options,

    You are using INIT_DONE, I hope this is pulled up externally

    with 10K.

    Yes, it is pulled up and as I said the EPC1 config done signal goes HI like any normally operating configuration chip.
