could you try with the same 5.3 kernel? That's probably the quickest
thing to try.

This means the FW+topology are newer, so 5.2.9 is a bit too old. I did 
check this and the kernel should be compatible (there was timestamping 
added to one of the IPCs), but maybe I missed something. In any case you
have received the first IPC message from FW ("FW_READY") which leads to
printing above info, so that is already indicating you are pretty far 
(e.g. authentication of the firmware has succeeded):

I recommend sticking to 1.3. Older versions won't work on your device, and 
there are no newer ones yet available (we are working towards 1.4 release 
now).
