Hello Team,
I have finished porting ddr3 from 512MiB to 1GiB successfully.I modified file "board/freescale/mx6ullevk/imximage.cfg" base on the parameters generated by script "I.MX6ULL_DDR3_Script_Aid_V0.01.xlsx" and tool "ddr_stress_tester_v3.00". At the beginning,the board was unable to start the kernel, and I try to comment uboot defconfig "CONFIG_IMX_OPTEE=y",it was able to start kernel normally.
What I want to know is what was the defconfig "CONFIG_IMX_OPTEE" used for and what is the impact on the system when commenting the defconfig "CONFIG_IMX_OPTEE=y".
My develop environment:
Board:imx6ull
Kernel:4.14.78
Thank you in advance.
Hi hong
for OPTEE usage one can look at sect.5.6.10 OP-TEE enablement
attached Yocto Guide, For memory check #define PHYS_SDRAM_SIZE
mx6ullevk.h\configs\include - uboot-imx - i.MX U-Boot
pay attention to cma size.
Best regards
igor
