Using firmware from 10.2 branch is a good idea. But did you rename it to firmware-2.bin? It should be called firmware-3.bin. > If this isn't the latest & greatest firmware, then where do I find > firmware-3.bin? ath10k-firmware.git is the correct location to find the firmware. > And If I should be using firmware-3.bin_10.2-00082-4-2, then are there > some release notes available for this?

The number three in "firmware-3.bin" is just an API number, just like the soname in shared libraries, to make it possible to have backwards compatibility with the firmware releases. Instead use version string like "10.2-00082-4-2" to identify between firmware releases. And yes, using firmware version 10.2-00082-4-2 is the firmware version I recommend to use at the moment. -- Kalle Valo _______________________________________________ ath10k mailing list ath10k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath10k
