Hello,

Can anyone please help me building uboot using yocto. I am not able to build it.

Thanks,
Ravi

Hello
Omni3576-SDK is primarily developed and tested on an X86 platform using Ubuntu 22.04 LTS.

Hello Eng33,

Thank you for the quick response.

I am able to build the kernel 6.1 using Yocto. I have clonned the scarthgap repo for that. As it is mentioned in the yocto/meta-rockchip/README.

I am getting errors only for building the u-boot. The error was due to the rk3576_defconfig is not available in u-boot stream from scarthgap. So I manually added the defconfig for that. Also added file dependencies which were not available. But in the end I am still not able to build u-boot.

I am using the x86 Ubuntu 22.04 LTS.

Thanks,
Ravi

Hello,
Could you provide detailed information, such as log details and the compilation process?
We typically use the SDK provided by the SoC for development, and RK has not provided support for the corresponding Yocto.
We recommend prioritizing the use of the methods provided by our SDK for compiling U-Boot and the kernel, and then you can port the rootfs yourself.

Hello Eng33,

Hi Ravi,
It seems that you have not properly configured or used the kernel we provided. We have not used rk3576-evb1-v10-linux.dts or rk3576-evb1-v10-linux.dtsi, so I think there is a configuration error on your part. I suggest you refer to our SDK and develop based on our SDK first.

Hi Eng33,

So you are asking me to build the SDK using build.sh script. Right?

One more thing I have rockchip SDK and I want to build it and run it on Luckfox omni3576. So how many changes do I need to make?

Thanks,
Ravi

Hi Ravi,
I didn't ask you to give me the build.sh script, but everything you've done is not based on the SDK we provided.
I think this goes beyond our technical support scope.

What .dtsi users can use ?
Does luckfox provided it rk3576 evb
dtsi to rockchips sdk ?

and to fix this

The error is "No rule to make target 'arch/arm64/boot/dts/rockchip/rk3576-evb1-v10-linux.dtb'. Stop.", dts files for RK3576 are missing.

can we use any config file from this command in RockChip SDK ?

ls kernel/arch/arm64/boot/dts/rockchip/ | grep rk3576

apologies for a lot of edited.
