Other Parts Discussed in Thread: BEAGLEBOARD-X15
Hi,
Just sharing study note.
I saw a unsolved thread on forum.
Thus, I write down the note for someone gets the same issue.
I will close the thread tomorrow.
Board:
TMDSIDK5749
(I guess, BeagleBoard-X15 is ok, too.)
Support:
Quectel EC20/EC21 GSM modem module. 3G/4G/LTE
Code base:
ti-processor-sdk-android-am57xx-06.03.00.106
Note:
The BSP seems that disabled DataUsage funcion.
Thus, there are some of code need to modify for GSM modem.
Function test:
Ran app "WebView browser Tester" and go to "ti.com"
Ran app "WebView browser Tester" and go to "youtube.com", play live camera.
Cmd for debug:
am start -n com.android.settings/.RadioInfo
am start -n com.android.phone/.MobileNetworkSettings
am start -a android.settings.NETWORK_OPERATOR_SETTINGS
am start -a android.settings.DATA_ROAMING_SETTINGS
am start -a android.settings.APN_SETTINGS
patch usage:
copy to overlay BSP
ex:
patch at
~/ec20_21_patch
BSP at
~/dk2/ti-processor-sdk-android-am57xx-06.03.00.106
cd ~/dk2/ti-processor-sdk-android-am57xx-06.03.00.106/board-support/
cp ~/ec20_21_patch/* . -r
# if you had built the BSP, you still build linux again for new ko file.
cd ~/dk2/ti-processor-sdk-android-am57xx-06.03.00.106/
make -j8 linux
make -j8 linux-dtbs
make -j8 u-boot

Caution:
You must add your SIM card information to patch/aosp-9.0/device/ti/beagle_x15/quectel/apns-conf.xml
The patch only includes part of android framework. The file of driver/lib, please contact Quectel's area agent to get them.
The image for verifying is at github, greatcattw/beagle_x15_ec20_ec21. I will remove it a few days.
