Xaf - host aplication not working and cache.img not generated

I have build android for Hikey960 successfully Now I am facing 2 issues .

  1. in the out folder cache.img is not generated
  2. I have integrated hifi xaf kernel driver and dsp firmware imge to the Android source tree
    and compiled and downloaded the image to device . Later compiled xaf -host application by using mm command and it generated binaries and I downloaded to the device by using adb
    when i test the xaf-dec-test binary its return 254 not woking then I checked
    log cat and found error is due to check failed in xf-fifo.c file line no 161 - problem related to
    /dev/hifi_misc this file is not opened .

Any body have idea about this ? Please guide me
