Hi Minh-Quang Nguyen,
Thanks for the information.
We are able to connect to internet through GPRS with existing binaries in the board.
we are also able to cross compile latest libosmocore, talloc and osmo-pcu. We loaded
latest osmo-pcu (from master ) to board and tried to test , but there is no internet
connectivity.
I see that there is no data received at osmo-pcu /osmo-bts as below, though assignment
is given to mobile
PCU side:
<0002> tbf.cpp:874 TBF(TFI=0 TLLI=0x00000000 DIR=UL STATE=WAIT ASSIGN) T3169 timeout
during transmission
<0002> tbf.cpp:893 - Assignment was on CCCH
<0002> tbf.cpp:899 - No uplink data received yet
BTS side:
<0009> pcu_sock.c:356 Sending RACH indication: qta=-3, ra=123, fn=647328

Let me know your comments
