一：MTK 平台查看eMMC和DDR的工作频率 eMMC： adb shell cat /sys/kernel/debug/mmc0/clock DDR： adb shell cat /sys/bus/platform/drivers/emi_clk_test/read_dram_data_rate 1. 获取 flash id: cat /sys/block/mmcblk0/device/cid kernel-3.18\drivers\mmc\core\Mmc.c MMC_DEV_ATTR(cid, "%08x%08x%08x%08x\n", card->raw_cid[0], card->raw_cid[1] 通过Flash Tool读去机器上的flash ID，进而判断机器上贴的是哪颗flash 关闭Flash Tool, 重新打开 download 菜单中“Help” -> open logs folder - "SP_FT_Dump_01-21-2019-13-34-04" -> BROM_DLL_V5.log 搜索“ID” -> "DEBUG: EMMCDeviceCheck::Dump(): [MVG INFO]: ID(0x13014E51324A39365210030A8085A3B3)" 二：增加 flash.步骤 1：判断 MCU 型号 在个文件添加 ls vendor/mediatek/proprietary/bootable/bootloader/preloader/tools/emigen/MT6735/ emigen.pl MemoryDeviceList_MT6735M.xls MemoryDeviceList_MT6735.xls MemoryDeviceList_MT6737M.xls MemoryDeviceList_MT6737T.xls 我通过./vendor/mediatek/proprietary/bootable/bootloader/preloader/custom/hys6737m_35_m0/hys6737m_35_m0.mk 4:MACH_TYPE=mt6737m 在 MemoryDeviceList_MT6737M 中添加时序 2：ddr时序 ddr认证列表和时序集成(mtk或者ddr原厂提供) 调试flash首先是id，mtk的规则是id匹配才能下载，id是可以通过datasheet或者工具来读出。 然后是时序，这一部分得有专门的工具和仪器，作为屌丝的我只能是猜 没有的到MTK online找 1.MTK online首页 2.QVL/DRL(新版合格器件清单)（左上角） 3. Step 1 : Select Product Line : Phone/Wearable Step 2 : Select Component : Memory Step 3 : Select Sub Type : eMMC+LPDDR3 Step 4 : Select Chips / Platforms : MT6737M && MT6737 Step 5 : Select Qualify Status : Qualifying Step 6 : Find 4.download 5.添加到MemoryDeviceList_MT6737M.xls 3： 添加 flash MemoryDeviceList_MT6737M.xls vendor/mediatek/proprietary/bootable/bootloader/preloader/custom/hys6737m_35_m0/inc/custom_MemoryDevice.h #define BOARD_ID MT6735_EVB // 兼容了 8种 //1+8 #define CS_PART_NUMBER[0] 08EMCP08_NL2DT227 #define CS_PART_NUMBER[1] H9TP64A8JDMCPR_KGM #define CS_PART_NUMBER[2] TYC0FH121638RA #define CS_PART_NUMBER[3] 08EMCP08_NL2CV100 #define CS_PART_NUMBER[4] KMK7X000VM_B314 #define CS_PART_NUMBER[5] SD7DP28C_8G #define CS_PART_NUMBER[6] H9TP65A8JDACPR_KGM #define CS_PART_NUMBER[7] KMK7U000VM_B309 4：查看out目录查看编译的flash型号，及DDR时序 ./out/target/product/hys6737m_35_m0/obj/PRELOADER_OBJ/inc/custom_emi.h EMI_SETTINGS emi_settings[] = { //08EMCP08_NL2DT227 { 0x0, /* sub_version */ 0x0202, /* TYPE */ 9, /* EMMC ID/FW ID checking length */ 0, /* FW length */ {0x70,0x01,0x00,0x45,0x48,0x38,0x45,0x42,0x38,0x0,0x0,0x0,0x0,0x0,0x0,0x0}, /* NAND_EMMC_ID */ {0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x0}, /* FW_ID */ 0x00025052, /* EMI_CONA_VAL */ 0xAA00AA00, /* DRAMC_DRVCTL0_VAL */ 0xAA00AA00, /* DRAMC_DRVCTL1_VAL */ 0x44584493, /* DRAMC_ACTIM_VAL */ 0x01000000, /* DRAMC_GDDR3CTL1_VAL */ 0xF0048483, /* DRAMC_CONF1_VAL */ 0xA00632D1, /* DRAMC_DDR2CTL_VAL */ 0xBF080401, /* DRAMC_TEST2_3_VAL */ 到这flash 就添加好了 三：有的可能烧入不了，或者无法开就需要调节 时序 电压和频率 1、修改DDR时序 vendor/mediatek/proprietary/bootable/bootloader/preloader/tools/emigen/MT6735/MemoryDeviceList_MT6737M.xls 1. 其中 H9CCNNN8GTMLAR 为 2G DRAM(8192+8192)，可配置为1G DRAM(8192 或 4096+4096)，其余均不需动 2. 其中MODE_REG3由“0x00020003”修改为“0x00010003” -> 增强驱动能力 3. 其中CONA_VAL不对会导致编译报错 Samsung KMK7U000VM_B309 MCP(eMMC+LPDDR2) 4096+4096 MT6735_EVB 0x1501004B375530304D (4096+4096) 1GDRAM KMK7U000VM_B309 Samsung 2048 2048 128 0 0 0 0 7634944 7460 (7460) 8GDROM 2、修改DDR频率 - 需要关闭DVFS 1. vendor/mediatek/proprietary/bootable/bootloader/preloader/platform/mt6735/src/drivers/pll2.c void mt_pll_post_init(void) + /* if (D2Plus == 1) { mt_mempll_init(DDR1280, PLL_MODE_1);

g_boot_time = get_timer(0); mtk_uart_init(UART_SRC_CLK_FRQ, CFG_LOG_BAUDRATE); mt_gpio_init(); clk_buf_all_on(); pwrap_init_preloader(); i2c_hw_init(); check_charger_boost_status(); #if !CFG_FPGA_PLATFORM pmic_ret = pmic_init(); + #ifdef DRAM_HQA + dram_HQA_adjust_voltage(); + #endif mt_pll_post_init(); #endif 2. 添加一些宏用做选择电压等级 vendor/mediatek/proprietary/bootable/bootloader/preloader/platform/mt6735/src/drivers/inc/emi.h + #define DRAM_HQA + #define HVcore + //#define NV + //#define LVcore + //#define HVcore_LVmem + //#define LVcore_HVmem 3. 实现调整电压的函数 vendor/mediatek/proprietary/bootable/bootloader/preloader/platform/mt6735/src/drivers/emi.c - #ifdef pmic_HQA_TCs // 此宏没开 + #if 1 + void dram_HQA_adjust_voltage(void) { #ifdef HVcore //HV (Vc=1.375V, Vm=1.3V pmic_Vcore_adjust(1);
