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

[Clemtos]

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?

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
