测试平台:UTV210BV04(友坚恒天)
软件平台:wince6.0
问题描述:
210的wince系统主频本来是800MHZ,如何改变了~
调试方法(修改为1GHZ主频):
1.找到\WINCE600\PLATFORM\COMMON\SRC\SOC\S5PV210_SEC_V1\OAL\INC下的InitSystem.h:
将 #defineARM_CLK_BL (CLK_800MHz)
修改为 #define ARM_CLK_BL (CLK_1GHz)
2、找到\WINCE600\PLATFORM\SMDKV210\SRC\COMMON\DVFS下的dvfs.c
将/* SYS_L1(800MHz)*/{ 1, 4, 4, 2, 4, 2, 5, 2, 4, DVS_L1_ARM, DVS_L0_INT};
/* SYS_L0(1GHz)*/{ 1, 4, 4, 2, 4, 2, 5, 2, 4, DVS_L0_ARM, DVS_L0_INT};
3、找到\WINCE600\PLATFORM\SMDKV210\SRC\BOOTLOADER\EBOOT下的main.c
将PMIC_VoltageSet(DVS_L0_ARM,DVS_L0_INT); //Voltage based on 800MHz修改为PMIC_VoltageSet(DVS_L1_ARM, DVS_L0_INT); //Voltage based on 1GHz
4、为了让编译成功:建议全部重新编译。Build——andvanced build commands——clean sysgen
注意:
记得重新烧写UT_EBOOT.nb0!
