AIF2 Loop back Not Working

aditya chaudhari1

Hi ,

We are Trying to run AIF2 on EVM 6670 WITH 30.72 mhz and 2 descriptor for tx queue.2 for free tx queue .2 for rx and 2 for free rx queue.After calling ISR for push and Pop data for Loop back we are getting descriptor count as :

[C66xx_0] rxQAxC entry count = 0
[C66xx_0] rxFqAxC entry count = 2
[C66xx_0] txQAxC entry count = 0
[C66xx_0] txFqAxC entry count = 2

but still data is not coming in RX queue.

Please suggest.

Your problem description is too simple and have no detail. it is hard to guess what happened on your side.

you may need to describe more details if you want me to give you any suggestion.

Albert

Hi,

Did you check AIF2 examples in BIOS MCSDK?
Most LTE examples are showing how to handle LTE20.

FYI, I enclosed the latest engineering release of AIF2LLD. You'll find in this package a README file describing how to update AIF2LLD in your environment and how to generate the test examples.

.\ti\drv\aif2\test\lte\singletone.c is a LTE FDD example that works in loopback mode as well.
