Hello All,
I'm tring to get my RIL up and working with android on BBB.
I'm using Telit HE910. This modem when connected creates 6 tty:
root@beagleboneblack:/ # ls /dev/ttyA*
/dev/ttyACM0
/dev/ttyACM1
/dev/ttyACM2
/dev/ttyACM3
/dev/ttyACM4
/dev/ttyACM5
/dev/ttyACM6
ACM0 and ACM3 are used for RIL. In my init.rc i set:
#Telit HE910
chown radio system /system/bin/chat
chown radio system /system/etc/options
chown radio system /system/etc/ppp/ip-up-ppp0
chown radio system /system/etc/ppp/ip-down-ppp0
chmod 0770 /system/etc/chat
chmod 0770 /system/etc/options
chmod 0770 /system/etc/ppp/ip-up-ppp0
chmod 0770 /system/etc/ppp/ip-down-ppp0
chown radio system /dev/ttyACM0
chown radio system /dev/ttyACM3
chmod 0770 /system/etc/hsdpa_connect
chmod 0770 /system/etc/hsdpa_disconnect
chown radio system /system/etc/hsdpa_connect
chown radio system /system/etc/hsdpa_disconnect
All files are in place i made a double check. Ril start... but after AT
handshake i receive an error.. here is the trace:
root@ubuntu:~/aosp/hardware/ril/reference-ril# adb logcat -b radio

Someone can give me a little hint with it? I've tried a lot of ways but
nothing help. Maybe I have to change other files .. more.. than ones marked
by telit for them custom RIL.
Ciao
