Since Buildroot commit [1] "package/gcc: switch to GCC 14.x as the
default", pine64_star64_defconfig compilation is failing in
u-boot with error:
drivers/video/dw_hdmi.c: In function 'dw_hdmi_write':
drivers/video/dw_hdmi.c:81:42: error: passing argument 2 of 'writeb' makes pointer from integer without a cast [-Wint-conversion]
See build failure [2].
Upstream U-Boot includes a support for this board since commit [3],
first included in v2024.07.
Upstream Kernel includes a support for this board since commit [4],
first included in v6.11.
This commit switches uboot and linux from the repository
https://github.com/Fishwaldo
to their respective upstream sources.
U-Boot is updated from the fork from a v2021.10 base to v2025.10.
The Linux Kernel is updated from the fork from a v5.15.131 base
to v6.12.56.
While at it, this commit updates the defconfig to the new convention:
- It adds custom hashes and enables BR2_DOWNLOAD_FORCE_CHECK_HASHES=y
- It switches to a glibc stable bootlin external toolchain
Note that the upstream uboot defconfig name for the pine64 star64
board is starfive_visionfive2 (which is in fact another, but very
similar board). The detection of the board is made inside the SPL.
See [5].
Finally, switching to upstream uboot and kernel required few
adjustments:
- The genimage.cfg is updated to use the "u-boot.itb" file produced by
U-Boot,
- In genimage.cfg, the uboot partition-type-uuid is changed to
xbootldr (the genimage human readable name), to follow the
recommendation of the UUID to use from [5],
- In extlinux.conf, rootwait is added in kernel arguments,
- The post-build.sh script and the star64-uboot-fit-image.its file
are removed: they are no longer needed, since U-Boot and Binman
are managing everything,
- BR2_TARGET_UBOOT_SPL_NAME is updated in the defconfig, to reflect
the file name generated by U-Boot,
- BR2_PACKAGE_HOST_STARFIVE_SPLTOOL is removed from the defconfig,
it is no longer needed, since upstream U-Boot produces the file
at the correct format,
- BR2_PACKAGE_HOST_UBOOT_TOOLS is also removed from the defconfig,
it is no longer needed since U-Boot uses Binman,
- the defconfig is updated to include the new uboot requirements
(BR2_TARGET_UBOOT_{NEEDS,USE}_*),
- the pine64_star64_defconfig entry is removed from .checkpackageignore
it is no longer needed.
This patch was tested on a Pine64 Star64 board V1.1,
PCB revision: 0xc1, BOM revision: A.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
