HPS & FPGA boot independently

Hello, We are booting FPGA and HPS independently from each other, i.e. each side is responsible only only for itself. But I have some misunderstanding of this concept. But HPS is configured as par...

    Hello Ran,

    Yes you can. You need to get the uboot and preloader separately from yocto project compilation. Also make sure to keep device tree (dtb) clear from any FPGA related device.

    HPS will help you to configure the pins, HPS-FPGA bridges, and help you to generate preloader and uboot later in SoC EDS.

    Hope this might help.

    thanks

    Hi Fawaz,

    One more on this issue if I may, does preloader configured sdram according to configuration of HPS in platform designer ? If so, doesn't it mean that a yocto preloader might not be suitable for a specific sdram-hps,?

    I ask just to be sure I understand it.

    Thanks!
