For a quick test, I cloned the board/amlogic package into an existing 
buildroot-git instance (2023.02-100-g9833247d49). In the build directory 
I ran:

wget 
https://raw.githubusercontent.com/mathieu-lm/libretech-cc-buildroot/master/configs/meson-gxl-s905x-libretech-cc_defconfig
mv meson-gxl-s905x-libretech-cc_defconfig .config
make nconfig
make uboot

It builds successfully:

>>> uboot v2020.01-rc5 Installing to target
>>> uboot v2020.01-rc5 Installing to images directory
cp -dpf /home/data/test/autobuild/build/uboot-v2020.01-rc5/u-boot.bin 
/home/data/test/autobuild/images/

You seem to use a different u-boot version than specified in the 
original configuration. You might need to update the u-boot defconfig in 
board/amlogic/s905x-libretech-cc/uboot and probably also the toolchain 
(currently gcc 6 based, from 2017).

Kind regards,
Andreas

Re: [Buildroot] U-boot stable asks for SYS_LOAD_ADDR when compiling for Le Potato

Hi Kenneth,

If the boot loader works, I would keep it, at least for now. The 
assembler (binutils-2.27) seems to have a problem with this construct:

https://github.com/u-boot/u-boot/blob/8be7b4629e87ff8db08dd087c81d58129d029bad/include/system-constants.h#L17-L19

Not sure if this is a toolchain issue or something missing in the 
configuration. Try updating your uboot defconfig with:

$ make uboot-nconfig
enter SYS_LOAD_ADDR, then
$ make uboot-savedefconfig
then copy defconfig to 
board/amlogic/s905x-libretech-cc/uboot/libretech-cc_defconfig

and rebuild u-boot (rm build/uboot-custom/.stamp* && make uboot). At 
least, uboot-2022.04 builds successfully with the Linaro toolchain 
(needs openssl).

Actually, I would upgrade Buildroot first, configure a buildroot 
toolchain (the Linaro toolchain misses sys/random.h), switch to 2022.04 
uboot (current buildroot default) and then check if the kernel can be 
upgraded (the head of libretech-linux is currently at 5.19.0).

<cut>

Kind regards,
Andreas

Toolchain and u-boot versions are static, the fault probably lies within 
the instructions in the README of [1].

Clean up your build and initialize it properly:

$ make clean
$ make meson-gxl-s905x-libretech-cc_defconfig

Then run 'make'.

[Buildroot] U-boot stable asks for SYS_LOAD_ADDR when compiling for Le Potato

[Kenneth Roland]

[-- Attachment #1.1: Type: text/plain, Size: 1521 bytes --]

As the subject says, I am unable to successfully compile buildroot for this board. I used this repo (https://github.com/mathieu-lm/libretech-cc-buildroot), as support for the Le Potato dev board isn't in mainstream. This fork isn't too old as it is dated 2020.02 in menu makeconfig​. I assume that because this repo is slightly dated that it doesn't account for newer changes for u-boot? Uname and logs are attached. I used the value 0x1000000 as given in the device's forums (https://forum.loverpi.com/discussion/748/u-boot-guide-for-le-potato-aml-s905x-cc).
u-boot Guide for Le Potato AML-S905X-CC<https://forum.loverpi.com/discussion/748/u-boot-guide-for-le-potato-aml-s905x-cc>
The boot priority of Le Potato is as follows: eMMC then SD. The current version of u-boot found in the images is the 2019.04 release.
