Hi I want to use FPGA Boot to run my baremetal system on CycloneVsoc board. But the AN709 needs to be updated, for preloader is no longer needed, all custom settings are made by Uboot/SPL settings. ...

    Hi

    when using standard flow,I found that it is hard to set the SPL to what I want to.

    I'm using eMMc as a boot source now, what I want to achieve is that the core run the SPL and then the SPL point to the Baremetal application.

    I use the same bulid flow to build up the SD card image with default SPL settings:

    P3 type: 2A u-boot-spl

    P1 type: Fat32 BM.bin-mkimage.bin

    P2 type: Ext3 Dummy file

    And I use dd to write into the eMMc card, but it failed to boot.

    Is that related to the SPL settings?
