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

[Ismael Gomez]

Hi Sheng-Hung,

What bandwidth are you using? The current open source implementation does
not provide a turbo decoder optimized for ARM processors therefore the
rates you will achieve will be quite low. Depending on the signal bw, you
may have real time faults and loose synchronization often.

Next time you send the logs, you don't really need to activate Debug mode.
Info mode in all layers (or MAC/PHY at least) is usually better.

thanks

Ismael
