Forum Post: C6670 AIF loopback on link 1 without link 0

Hello

I'm trying to run AIF2 example Aif2_Cpri_Generic_Packet_Test from CSL (PDK C6670 1.1.1.6). This test is passed with AIF Link 0 in loopback mode. But then i try to use Link 1 instead of Link 0 test is busy in this loop:

while (hostRxCount < 8) {   // Get current descriptor count for host RX queue   hostRxCount = get_descriptor_count(HOST_RX_Q);   if (hostRxCount != 0)     printf(" Number of monolithic packets received in RX queue: %d\n", hostRxCount); }

That i need todo toworkwiththis test at AIF Link 1?

I also try example from AIF2LLD (aif2GenericTestProject). This example also successfully passed with Link 0 and with Link 0 + Link 1. But with enabled only Link 1 this test also failed.

I'm using Advantech TMDXEVMC6670 board Rev. A103-1.

Thanks.
