SK-AM62: kernel building error

James Lee

Part Number: SK-AM62

Hello Ti,

I rebuild the kernel of am62 from ti-processor-sdk-linux-am62xx-evm-08.05.00.21 sdk.

When I install module with "sudo make ARCH=$target INSTALL_MOD_PATH=module_install_path modules_install", there are following message and It doesn't appear before:

arch/arm64/Makefile:25: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum
sed: can't read modules.order: No such file or directory
make[1]: *** [/home/a/ti/ti-processor-sdk-linux-am62xx-evm-08.05.00.21/board-support/linux-5.10.153+gitAUTOINC+3eee621d16-g3eee621d16/Makefile:1460: _modinst_] Error 2
make: *** [../Makefile:185: __sub-make] Error 2

Hi James,

Can you please add "CROSS_COMPILE=<the toolchain>" in the command to see if it solves the issue?

Hi Bin,

It still appears the same error message.

Besides, when I build kernel module with "make ARCH=$target CROSS_COMPILE=<the toolchain> modules", It has the same error message.

Hi James,

I hope you replaced '<the toolchain>' with the real path of your toolchain.

Anyway, please attach the full list of commands you used to compile the kernel. You can use 'history' command to get all the commands you used.

Hi Bin,

Of cource. I use the toolchain with aarch64-none-linux-gnu and the following is the full command:

make ARCH=arm64 CROSS_COMPILE=aarch64-none-linux-gnu- modules

Hi James,

Is the toolchain in the $PATH?

What command "aarch64-none-linux-gnu-gcc" says?

Please show all the commends you used to build the kernel.

By the way, you can build kernel in the SDK top level directory using just a single command:

$ make linux

To install the kernel image and modules to a mounted SD card:

$ sudo DESTDIR=<sdcard-mounting-point> make linux_install
