Overview
The DART-MX8M is capable of adding a Mini PCI-E based modem to support LTE connectivity.
Note:
- At present we support LTE Quectel EC25.
- Other modules could be supported please contact your module vendor.
- Below steps are validated and tested upto Android 11 version.
Hardware Interface
- Quectel EC25 mPCI-E Hardware module with a SIM card.
- mPCI-E interface with USB support, like the one on the DT8MCustomBoard (note that the Symphony-Board mPCI-E interface does not support USB).
Hardware Availability and Setup
- Connect SIM card to mPCIe-E module.
- Connect mPCI-E Module to J23.
Note: Make sure your SIM provider is supporting mPCI-E module specification of the network.
Software Setup
Make sure you have the required hardware as per above.
RIL Setup
By default, the build doesn't have a RIL setup.
To add the RIL support follow the below steps.
Register and get access to the download zone https://www.quectel.com/login
Download Quectel_Android_RIL_Driver_XX.Y.ZZ_master_<release>.tgz
Where (XX.Y.ZZ are version numbers from quectel and <release> can be alpha/beta etc)
Adding Driver to build
Edit imx8m_var_dart_android_defconfig and enable following
Device Drivers-> Network device support -> USB Network Adapters -> Multi-purpose USB Networking Framework -> <*> QMI WWAN driver for Qualcomm MSM based 3G and LTE modems
and enable following config:
CONFIG_USB_NET_QMI_WWAN=y
Downloading and adding Quectel RIL to build
$ cd ~/var_imx-o8.1.0_1.3.0_8m/android_build $ mkdir -p vendor/quectel/ $ tar -xvf ~/Downloads/Quectel_Android_RIL_Driver_V3.3.49_master_beta.tgz -C vendor/quectel/
Add Quectel libraries to build
Edit device/variscite/imx8m/dart_mx8m/dart_mx8m.mk and add following code
TARGET_HAVE_QUECTEL_RIL := true ifeq ($(TARGET_HAVE_QUECTEL_RIL),true) # wifionly device PRODUCT_PROPERTY_OVERRIDES += \ ro.radio.noril=false PRODUCT_COPY_FILES += \ vendor/quectel/libquectel-ril/arm64-v8a/libreference-ril.so:vendor/lib64/hw/libreferece-ril.so \ vendor/quectel/libquectel-ril/arm64-v8a/ip-up:vendor/bin/ip-up \ vendor/quectel/libquectel-ril/arm64-v8a/chat:vendor/bin/chat \ vendor/quectel/libquectel-ril/arm64-v8a/ip-down:vendor/bin/ip-down \ vendor/quectel/libquectel-ril/ql-ril.conf:vendor/etc/ql-ril.conf fi
Add Quectel libraries in the ril-daemon service
Edit device/variscite/imx8m/dart_mx8m/init.rc and add following code
service ril-daemon /vendor/bin/hw/rild -l vendor/lib64/hw/ class main user radio group radio cache inet misc audio sdcard_rw log capabilities BLOCK_SUSPEND NET_ADMIN NET_RAW
Add RILD in the HIDL service
Edit device/variscite/imx8m/dart_mx8m/manifest.xml and add following code
