[LGE-CTO] booting failure with 4G DRAM with OPTE

Jessie_Lee — Fri, 29 Jan 2021 07:14:29 GMT

Hi @haidong_zheng

customer is LGE-CTO

project is IFE (In Flight Entertainment)

silicon : i.MX8MQ

BSP : L5.4.70.

issue : customer met booting failure with suck at "starting kernel ...." log.

customer applied below patch and with ddr_timing.c from ddr stress tool.

with below patch + removed OPTEE ==> 4G booting is okay and also 4G memory seems to be okay on target board.

But, below patch + OPTEE , customer met booting failure with stuck at "starting kernel.."

below is bdinfo with booting failure. i am not sure but does below glue text address is as below. it is for your reference.

@Jessie_Lee :

We had a way to support 8MQ 4GB memory without changing OPTEE load address.

Please refer to: https://community.nxp.com/t5/iMX-and-Vybrid-Support/8M-Scale-845-850-board-4GB-memory-support-summary/ta-p/1118187

Hi @kevin_fu :

I don't know what's your exact request, any way I past below for your reference:

ifneq (,$(filter $(PLATFORM_FLAVOR),mx8mqevk))

-CFG_DDR_SIZE ?= 0xc0000000

+CFG_DDR_SIZE ?= 0x100000000

+CFG_TZDRAM_START ?= 0xfe000000

CFG_UART_BASE ?= UART1_BASE

+$(call force,CFG_CORE_LARGE_PHYS_ADDR,y)

+$(call force,CFG_CORE_ARM64_PA_BITS,36)

endif
