Hi RShal4,

Micron's MT25Q devices is supported in Quartus Prime 17.1 and later.

MT25Q is not supported in Quartus 15.1. Please use the latest Quartus version if yo want to use MT25Q device.

Please refer to following link to enable Micron's MT25Q in Intel Quartus Prime:

Hi JonSnow,

We upgraded to quartus 18.1, but the behavior is the same.

Only after changing I/O access from Quad to Standard, we managed to write info flash !

But we need the bandwidth of quad access...

More info: We use "altera flash controller" for our boot qspi.

Best Regards,

ranran

    Hi RShal4,

    Can you try to use "Quad SPI controller II" with MT25Q device?

    Sometime Quad SPI controller I have some issue with MT25Q device. However, Quad SPI controller II is working with MT25Q with direct access.

    Kindly try this out. Please let me know the results.

    Thanks.

    Hello JonSnow,

    On trying to use the same IP with 512 qspi we can reach only 512M OK, but the qspi is 1G, we then tried to change the module in qsys to N25Q00AA1G1240 (no other 1G MT25Q option is available, but then on compile we get error

    instantiated_with_wrong_parameters_error_see_comment_above becuase ADDR_WIDTH != 24,

    Trying to use generic quad controller II, as you suggested, we get errors that "COMPOSITION_CALLBACK" is not supported with our quartus version (unfortunately we can't upgrade above 15.1)

    Is there any idea how we can handle this ?

    Thanks!
