Proper setting for Uboot/SPL

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


Yes it would not launch .

You would need to load the program( .img file) into the ram from the sd card.

In uboot try the command below:


//to copy application to the ram address

load mmc 0:1 \${loadaddr}


//test to see if the application is loaded successful

iminfo ${loadaddr}


//jump to application

go ${loadaddr}

Now I'm using USM to communicate with the board, I can visit the emmc on /dev/sda.

I loaded the image to /dev/sda but BootROM can't find out where SPL was and keep resetting.

So how should I do to let the BootROM find the SPL?

What changes need to be done in the SPL setting?

What changes need to be done in the image making?

Thank you.
