Can't create custom SPL - Board doesn't boot

eng.fernandosilva · March 2, 2024, 1:20am

I’m working in porting a bootloader to VisionFive instead of using standard U-Boot SPL. I have been looking into the boot specs at JH7110 Boot User Guide (rvspace.org) but can’t find a way to boot using the offset where SPL should live. Is there an additional header, padding or something else to be taken into consideration?
My linker is very similar to u-boot/arch/riscv/cpu/u-boot-spl.lds at master · u-boot/u-boot (github.com) but still no lucky…
Thank you in advance!

SPL image needs to be prepared with

github.com

starfive-tech/Tools/blob/master/spl_tool/README.md

and depends on what media you use (qspi/emmc/sdcard), it needs to be flashed differently. For qspi, it’s at offset 0. For sdcard/emmc, see this:
