[srslte-users] srsUE which installing on odroid xu4 can't finish random access

[李聖弘]

Hi SRS members,

 

We tried to install srsUE on odroid xu4(ARM) to connect OAIeNB(running on
intel cpu) and the installation had been done. 

Now, the srsUE can receive information of mib, sib1 and sib2, but there are
some problems in random access.

The srsUE always cant receives the respone of RA from OAIeNB. The Attachment
is the log file about the step of preamble 1.

Ue_log_arm mean that the connection between oaieNB and srsUE which
installing on odroid xu4.

Ue_log_intel mean that the connection between oaieNB and srsUE which
installing on intel cpu.

There are some different in those two log files and the case of ue_log_intel
always can finish random access after transmitting preamble 1.

We had tried to alter the parameters on configure file about PRACH configure
in oaieNB, but we still cant resolve this issue. 

Is there any method to solve the problem or any help to cover it.

 

The operating system are all ubuntu14.04 on odroid xu4 and computer. The
srsUE and srsLTE both are master version and we use B210 to transmit signals
between UE and eNB.

 

Best Regards,

Sheng-Hung
