    Hi Shraga,

    I am sorry, those configuration pin are needed for configuration purposes. We cannot disable them.

    So, is this function work?

    Dear YL.

    it is very strange

    when we are load a POF file it is loaded at low temperature but not working

    when we load a SOF file it is loaded and working

    Hi Shraga,

    This is weird. Can you try to recompile the bitstream and try again?

    Hi there,

    We experienced the exact same problem here on ~20 components 10M16SCU169A7G.

    MAX10 do not configure from the integrated flash when temperature drop bellow ~15°C.

    We shall power cycle the MAX10 until it get configured and respond to our system at start-up.

    When it get configured, we can hard freeze it, he still works as intended.

    Does Intel/Altera has investigated the issue ?

    BR,

    Marc.

    More precisely, it looks like the configuration delay increase a lot when the device is cold.

    It can take several minutes before MAX10 answer to the communication bus (~15 min worst case we had).

    Power cycling it seems to make configuration longer, like if the configuration started from scratch at the same incredibly low speed.

    Integrated in the global system, with timeouts and auto power cycle, made debugging quite confusing…
