오버클럭 및 메모리 1기가 업데이트 방법

1. 오버클럭 방법

1. Kernel config :

           System Type      > TCC892x HDMI Dongle Clock Mode        à CONFIG_HDMI_DONGLE_CLOCK_HIGH_SPEED

                                 > CPU high-speed clock                        à CONFIG_CPU_HIGHSPEED

 

           CPU Power Management > CPU Frequency scaling > Default CPUFreq governor         à Ondemand

 

 

2. kernel/arch/arm/mach-tcc892x/tcc_clocktbl_ddr3_nn.h수정

           CLOCK Table : 변경할 내용은 없습니다. 참조만 하시면 될 듯 싶습니다.

           static struct tcc_freq_table_t gtClockLimitTable[]

 

           하기 테이블을 아래와 같이 적용

           const struct tcc_freq_table_t gtHdmiClockLimitTable = {

                  0, 386880, 600000,      0, 243040,      0,      0,      0,      0          // Core 1.30V

           };

2. 메모리 1기가 업데이트 방법

1. bootable\bootloader\lk\target\tcc8920st_evm\rules.mk

 

#------------------------------------------------------------------

# Main Memory manufacturer and type

#------------------------------------------------------------------

#-DEFINES += CONFIG_DDR3_NT5CB256M8GN_CG

DEFINES += CONFIG_DDR3_H5TC4G83MFR_H9A

DEFINES += DRAM_DDR3

1G RAM 설정에 따른 변경 부분은 아래 2 부분 입니다.

 

1. bootable\bootloader\lk\target\tcc8920st_evm\rules.mk

#------------------------------------------------------------------

# Define memory size in MB

#------------------------------------------------------------------

#-TCC_MEM_SIZE := 512

#-DEFINES += CONFIG_TCC_MEM_512MB

TCC_MEM_SIZE := 1024

DEFINES += CONFIG_TCC_MEM_1024MB

2. kernel - make menuconfig

1) System Type select

2 - 1) DRAM Memory Size (1024MB) select

2 - 2) DDR3 settings (Hynix DDR3_H5TC4G83MFR_H9A) select
