I rename the bin file  . and capture new full logs from booting to firmware error . 
The error still happened. Please help to check it .
I want to know whether the new firmware bin are updated  the right one  in this git ?
If the firmware is good , the errors should be gone .


keep up the good work

You didn't attach a complete log so it's hard to tell. ath10k tends to print a few messages that may look like an error but aren't (there's a fallback mechanism for finding firmware files which is overly verbose).

@Perry: You need to rename the
firmware-4.bin_WLAN.RM.2.0-00180-QCARMSWPZ-1 to firmware-4.bin in case you merely mirrored the github repo.

@Kalle: I think it'd be very useful to maintain ath10k-firmware in a way so that it is easier to the uninitiated to `git clone` it into /lib/firmware, e.g. maintain firmware-X.bin symlinks in each QCAxxx/hw.y/ to the latest one. Thoughts?
