jh7110_uboot_spl's Introduction

*** DEPRECATED ***

This code was upstreamed into https://github.com/starfive-tech/Tools/, replacing proprietary one,
with more features added by StarFive developers, and now maintained there. This version will be archived.

DESCRIPTION

A replacement for VisionFive2 SDK spl_tool which happened to be proprietary.
Use only with VisionFive2 boards to make u-boot-spl.bin.normal.out image!

DISCLAIMER

Use at your own risk! I, Rys Andrey, don't bear any responsibility for
your broken hardware. Check the image carefully with your eyes before
flashing it to real device!

WHY

Cause I want it to run on RISC-V when building U-Boot there. I don't want
to resort to qemu-x86_64 to run a tool which does something very simple.

OFFICIAL DOCUMENTATION

UPD: Please see https://doc-en.rvspace.org/VisionFive2/Developer_Guide/JH7110_Boot_UG.pdf for complete guide on
how to make bootable images for various boot sources (QSPI, eMMC, SD). It also covers this source aswell now.

jh7110_uboot_spl's Issues

u-boot-spl.bin too big on GCC12

Hi, thanks for creating this tool.

When running it on a u-boot-spl.bin that was generated using default configuration (from the SDK) but on GCC12, the created file is slightly too big (no matter if -Os is added).

The proprietary tool also accepts the generated blob, but this tool bails out with the size limit warning. Also the size limit is somehow misleading, as at least the input file is smaller.

# added this debug output
size: 129760, max 129024
File too large! Please rebuild your SPL with -Os. Maximum allowed size is 130048 bytes.

I did not yet check the details - maybe it is due to a different aligning or a different linker script. Anyways, I'm wondering if the created artifact of the proprietary tool is actually valid. And if so, where this limit comes from.
