Hello,

I am working on the PolarFire RISC-V icicle kit and use u-boot to start my application. I configured the firmware to start u-boot on all harts (cores) and found out that u-boot uses a "HART lottery system" to decide which core/hart it runs on. In my special case I want u-boot to start on the first hart and the other harts shall wait for the interrupt.

Replace the hart lottery with a check on tp.

--Sean

I cannot use the "saveenv" but I compile the u-boot myself. Is there a way to compile the u-boot to ignore the "HART lottery system" and use the first hart?

Thank you in advance.
