SIM卡(單卡)配置

SIM卡相關配置

1.
GPIO90---》BPI8
GPIO91---》BPI9
GPIO92---》BPI10

2.ProjectConfig.mk：MTK_PROTOCOL1_RAT_CONFIG = Lf/Lt/W/G

3.單卡
device.mk：PRODUCT_PROPERTY_OVERRIDES += persist.radio.multisim.config=ss
ProjectConfig.mk：MTK_MULTI_SIM_SUPPORT = ss

若是硬件沒有接外部sim switch即單卡，則配置以下（不置空會出現SIM卡不識別問題）：
alps/kernel-3.10/arch/arm/configs/k95v21_defconfig
CONFIG_CUSTOM_KERNEL_SSW=" "

alps/device/mediatek/k95v21/ProjectConfig.mk
CUSTOM_KERNEL_SSW =

4.熱插拔
ProjectConfig.mk: MTK_SIM_HOT_SWAP = yes
MTK_SIM_HOT_SWAP_COMMON_SLOT = no
