Compiling u-boot-imx after driver update results in fail

Clemtos — Wed, 17 Jul 2024 17:58:53 GMT

Hello,

I tried updating the mx6ul_14x14_evk_config/.config file by applying a .bbappend on it and it worked, my driver is going from:

# CONFIG_DRIVER_TI_CPSW is not set to CONFIG_DRIVER_TI_CPSW=y

But when I do "bitbake u-boot-imx" I have the following compiling error:

.config:1752:warning: override: reassigning to symbol DRIVER_TI_CPSW

And a bunch of other errors regarding drivers in the log file. I don't know why updating a driver might corrupt the compile process of the u-boot!

See full log file as attached.

Thanks

Hi,

Thank you for your interest in NXP Semiconductor products,

I found this record of u-boot modifications in yocto which (in the addendum) seems to correctly override the defconfig, could you try it?

Regards

Hi Joseph,

Unfortunately I already did what this SO is doing by applying a patch but it was not working.

I created a .bbappend file with the following:

FILESEXTRAPATHS:preprend := "${THISDIR}/files:" SRC_URI:append = " file://u-boot-custom.cfg" do_configure:append() { cat ${WORKDIR}/u-boot-custom.cfg >> ${B}/mx6ul_14x14_evk_config/.config }

But when I was running bitbake u-boot-imx I had a compile error:

fatal error: asm/arch/cpu.h: No such file or directory 25 | #include <asm/arch/cpu.h>

So I manually modified the file to remove the asm/arch in the include to be able to successfully compile. I don't know if my modifications were correct but it compiled the u-boot-imx.

After this I generated a .wic image with the new u-boot and flashed it on my SD Card but I encounter a boot problem:

Any clue ? Thanks a lot
