Hi Andre, Justin,
I have been able to install the srsLTE 18.12 on the Jetson Tx2 board with
the updated CMakeLists.txt from the "aarch_fix" branch. However, on the way
of compilation I got an error for HWCAP in the *lib/src/common/*
arch_select.cc file which I commented to return "generic" in the function
arm_get_isa() . After that compilation went fine.
Then I tried to test the enodeB on the jetson board connected with a USRP
B210. I executed the srsepc and srsenb on the Jetson with example config
files. Now it does not throw any error in the console and and the LEDs on
the usrp blinks and waits to receive signal from UE. After that when I
start srsUE from a laptop (1 meter away from the eNodeB), the UE is not
able to attach and prints "Radio Link Failure".
I checked the epc.log and it receives the attach requests and successfully
authenticates the user's IMSI and other details. However, on ue.log, it
prints "sync=out-of-sync from channel estimator" and SNR is around -15 to
-20 dB and RSRP is around -100 dB.
Could you please help me to identify the possible reason for the radio link
failure.
Thanks & Regards,
Sabur
