Hi Syam,


The bridge enabled which I mentioned is after u-boot image loaded where you can stop auto boot and type "bridge enabled".


May I know how you enable the logs which shows those info regarding CLOCK?

Are you booting up with QSPI or sdcard? The logs which I normally see when boot up is like the example logs in the document below:

https://rocketboards.org/foswiki/Documentation/BuildingBootloaderCycloneVAndArria10#Cyclone_V_SoC_45_Boot_from_SD_Card


Other than that, may I know under the SDRAM->PHY Settings of the Cyclone V HPS IP settings, what is the Memory clock frequency{MEM_CLK_FREQ} that you set?



Thanks.

Regards,

Aik Eu

    Hi Aik

    We are working with Quartus 18.1. The rocket board link you shared is for the latest Quartus 21.1. For 18.1 the appropriate link would be this - https://rocketboards.org/foswiki/Documentation/EmbeddedLinuxBeginnerSGuide

    The preloader boot log automatically gets printed via the serial interface on power up and it comes from the preloader software.

    We are booting from the SD Card.

    SDRAM->PHY Settings of the Cyclone V HPS is shown below.
