I am developing diagnostic code for A104DE on a Oracle Linux UEK8 system with Wanpipe driver: wanpipe-7.0.34. The diagnostic code was based on HDLC test (Load test – loopback test) file (wanpipe-7.0.34\api\libsangoma\examples\hdlc_test\hdlc_test.c) in wanpipe-7.0.34. The code was almost no change from the orignal.
In this system, I did configuration with:“wancfg_tdmapi --fe_media=T1 --fe_clock=MASTER --silent”, also ran digital loopback script --loop.sh and echo canceller script --mpd.sh. Everything seemed normal and good. But it got Tx Nothing Error. Of course no Rx data. The loopback test was failed.
On a desktop computer, I installed the same software: Dahdi, Libpri, Asterisk, and Wanpipe driver on Ubuntu with the same A104DE card. Ran the same test, and it was passed.
Would you think what I was missing and it caused the issue?
