    reproduced with sof-byt-nocodec.tplg but with a different error (which seems more difficult to handle)
    dmesg.log

    No issues whatsoever with APL also in nocodec topology, not sure why.

    Firmware load failed after booting. So tests were blocked.

    @lyakh looks like a topology component double free attempt (1st time may set it to NULL).

    Summary:
    This issue cannot be reproduced on BYT-nocodec using the build on Dec 7.
    There is no Kernel Panic.

    Test steps:

    1. kmod_scripts/sof_bootone.sh
    2. aplay -l
    **** List of PLAYBACK Hardware Devices ****
card 0: sofnocodec [sof-nocodec], device 0: Passthrough (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
    1. arecord -l
    **** List of CAPTURE Hardware Devices ****
card 0: sofnocodec [sof-nocodec], device 0: Passthrough (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

    Test env:
    sof master: b5d6c71 #Dec 7
    kernel sof-dev: a71221d #Dec 7
    tplg: test-ssp2-mclk-0-I2S-volume-s16le-s16le-48k-19200k-nocodec.tplg

    @markyang it's good that we don't have kernel panic during unloading/reloading here. But the topology loaded seems wrong. https://github.com/thesofproject/sof/blob/master/tools/topology/sof-byt-rt5651.m4 should be used for Minnowboard with AL5651.

    Could you help to

    • check why test-ssp2-mclk-0-I2S-volume-s16le-s16le-48k-19200k-nocodec.tplg is loaded here?
    • is unload/reload healthy with byt-rt5651.m4 for Minnow with ALC5651?
