@ -270,18 +270,21 @@ Following figure shows the detailed configuration point in AD9361, driver (.c fi
To debug/see the basic driver behaviour, you could turn on **dmesg** message printing by
```
See all printing:
./sdrctl dev sdr0 set reg drv_tx 7 X
./sdrctl dev sdr0 set reg drv_rx 7 X
The bit in value X controls what type of information will be printed to the dmesg (0--no print; 1--print).
bit0: error message
bit1: regular message for unicast packet (openwifi_tx/openwifi_tx_interrupt/openwifi_rx_interrupt)
bit2: regular message for broadcast packet
For example, regular message for unicast packet and error message
./sdrctl dev sdr0 set reg drv_tx 7 3
./sdrctl dev sdr0 set reg drv_rx 7 3
See only error printing:
For example, error message only:
./sdrctl dev sdr0 set reg drv_tx 7 1
./sdrctl dev sdr0 set reg drv_rx 7 1
See only regular printing:
./sdrctl dev sdr0 set reg drv_tx 7 2
./sdrctl dev sdr0 set reg drv_rx 7 2
Turn off printing:
./sdrctl dev sdr0 set reg drv_tx 7 0
./sdrctl dev sdr0 set reg drv_rx 7 0
```
and use **dmesg** command in Linux to see those messages. Regular printing includes tx/rx packet information when a packet is sent or received. Error printing has WARNING information if something abnormal happens. You can search "printk" in sdr.c to see all the printing points.
