工作指南
1. 5M (CU) 配置：
[DSDS 5M Project config 选项]
[WorldPhone CSFB]:5M
MTK_LTE_SUPPORT=yes
MTK_ENABLE_MD1=yes
MTK_MD1_SUPPORT=5
CUSTOM_MODEM=mtk6753_65c_l1_lttg_dsds mtk6753_65c_l1_lwg_dsds
MTK_SHARE_MODEM_SUPPORT=2
MTK_SHARE_MODEM_CURRENT=2
MTK_WORLD_PHONE=yes
MTK_UMTS_TDD128_MODE=no
kernel config:
CONFIG_MTK_ENABLE_MD1=y
CONFIG_MTK_MD1_SUPPORT=5
#CONFIG_MTK_UMTS_TDD128_MODE is not set
2. 5M < == > 4M (CT)：
[Switchable Features 选项]
[4M]
MTK_SVLTE_LCG_SUPPORT = yes
MTK_SVLTE_SUPPORT = yes
[5M]
MTK_SVLTE_LCG_SUPPORT = no
MTK_SVLTE_SUPPORT = yes
3. CT == > OM (C2K) ：
[Switchable_Operators 选项]
BOOT_LOGO={LCM}
CUSTOM_MODEM = {modem}
(mtk6753_65c_l1_c2K_svlte_om
mtk6753_65c_l1_lttg_dsds
mtk6753_65c_l1_lwg_dsds)
OPTR_SPEC_SEG_DEF=NONE
MTK_DEVREG_APP = no
MTK_CT4GREG_APP = no
MTK_CTPPPOE_SUPPORT = no
MTK_MD_SBP_CUSTOM_VALUE=0
kernel config:
CONFIG_MTK_MD_SBP_CUSTOM_VALUE=\"\"
MTK_SIP_SUPPORT = yes
MTK_WORLD_PHONE=yes
MTK_FLIGHT_MODE_POWER_OFF_MD=yes
MTK_DISABLE_CAPABILITY_SWITCH=no
MTK_WEATHER_WIDGET_APP=yes
MTK_WEATHER_PROVIDER_APP=yes
4. OM (C2K) == > CT
[Switchable_Operators 选项]
BOOT_LOGO={LCM}
CUSTOM_MODEM = {modem}
(mtk6753_65c_l1_c2k_svlte
mtk6753_65c_l1_lwg_dsds)
OPTR_SPEC_SEG_DEF=OP09_SPEC0212_SEGDEFAULT
MTK_DEVREG_APP = yes
MTK_CT4GREG_APP = yes
MTK_CTPPPOE_SUPPORT = yes
MTK_MD_SBP_CUSTOM_VALUE=0x9
kernel config:
CONFIG_MTK_MD_SBP_CUSTOM_VALUE=\"0x9\"
MTK_SIP_SUPPORT = no
MTK_WORLD_PHONE=no
MTK_FLIGHT_MODE_POWER_OFF_MD=no
MTK_DISABLE_CAPABILITY_SWITCH=yes
MTK_WEATHER_WIDGET_APP=no
MTK_WEATHER_PROVIDER_APP=no
注：如电信库必须配置CT
第4步骤，CUSTOM_MODEM 配置如果要求6M，添加上lttg，否则不加
MTK_DEVREG_APP = yes
MTK_CT4GREG_APP = yes
CT6M_SUPPORT = yes
MTK_C2K_SLOT2_SUPPORT = yes
卡2可以支持CDMA卡，3/4G能力可以自由切换，不受C卡
