Thanks for replying, I found the dts file related to cpu in linux/arch/arm64/boot/dts/hisilicon/hi3660.dtsi. This may help.

11 months ago I tried to edit the DTB files and it seems not realistic and not an easy task.
And I tried the methods used in this issue #3643, change the value of CFG_TEE_CORE_NB_CORE to 1 and change the return value of get_core_pos() to 0. The hikey960 board still stucks in the booting process.
Is there any more suggestions to running the whole optee_os and linux kernel with only one core on hikey960 board?

Add maxcpus=1 to the kernel command line.

maxcpus=1to the kernel command line.
Thanks for your suggestion!
I edited patches_hikey/grub/grub_uart6.cfg to add the maxcpus=1 option, and flash the images to the board. the kernel stop to wake up the other 7 cores, but encountered with a new kernel panic:

I tried to edit
$(call force,CFG_TEE_CORE_NB_CORE,8)to$(call force,CFG_TEE_CORE_NB_CORE,1), but the operating system will stuck at some point of booting process. Looks like linux tried to wake up another seven cores, but failed. Is this something related to SMP?I found this patch showed that the
CFG_TEE_CORE_NB_COREis not changable. Is there any other way to use only one core to run OPTEE OS on hikey960 board?
