how to get i.mx8m plus tool chain

[Dawei]

Hello,
How can I get the binary files of the i.MX8M Plus cross-compilation toolchain and related operating instructions(user guide)?
and how to compile to support Qt5/Qt6

How to get the uboot/kernel sourcecode address of the i.MX8M Plus?

thanks

Hello,

Please refer to Yocto User's guide for installing and building the BSP.

https://www.nxp.com.cn/docs/en/user-guide/IMX_YOCTO_PROJECT_USERS_GUIDE.pdf

For toolchain and building kernel/u-boot standalone, please refer to the i.MX Linux User’s Guide​ Chapter 4.5.12 "How to build U-Boot and Kernel in standalone environment".

FYI. All the BSP documentation could be downloaded from here:

I do it as the guide document, but when do this step, it stops here : repo init -u https://source.codeaurora.org/external/imx/imx-manifestimx-4.9.88-2.0.0_ga.xml I confium my net is ok ,and I can open this website in the exploer。 So what is the problem？ How can I install the tool chain online? Thank you!

codeaurora server is shutdown
you need change to github

new imx-manifest on https://github.com/nxp-imx/imx-manifest

The instructions in the linked document are incomplete, and an error will be reported if you follow the operation. I just want to compile a u-boot image directly from source without yocto (it's too big), is there a simple example?

CC spl/arch/arm/lib/reloc_aarch64_efi.o

I just want to build an u-boot image for "8MPLUSLPD4-EVK" without YOCTO.

Thanks very much.

I would still suggest you to use Yocto because we tested it and support it. If you use other env./tool to compile the source code, you may need to spend a lot of time to configure/debug the source code building.
