USDPAA Application Hello_Reflector

Hello friends, i got a problem when i using the usdpaa application: hello_reflector.

according to the sdk info center, i had modified the dts file just like the following :

ethernet@1 {

  compatible = "fsl,t1040-dpa-ethernet-init", "fsl,dpa-ethernet-init";

  fsl,bman-buffer-pools = <&bp7 &bp8 &bp9>;

  fsl,qman-frame-queues-rx = <0x52 1 0x53 1>;

  fsl,qman-frame-queues-tx = <0x72 1 0x73 1>;

  };

after system  ready,  i input "ifconfig" command  to ensure the ethernet configuration, none ethernet inerface shown but loopback interface. the driver "fsl,dpa-ethernet-init" may be wrong found nothing in source code, so how can i do for the question? thanks much more for your help. thanks...

The behaviour you are observing is as expected. When you specify

the interface property "dpa-ethernet-init", Linux does only the

basic intitialization for the interface, leaving everything else

to USDPAA.  The kernel cannot exchange any data through this interface

and ifconfig does not see it. If you are going to work with reflector,

this is correct.  Details can be found here:

Note, the SDK provides a ready Device Tree file for USDPAA applications

for your processor, t1040d4rdb-usdpaa.dts

Have a great day,
