I'm running a master build on Archer C6 v3.2 (mt7631).
The 5Ghz Wi-Fi chipset of this device is an MT7613BEN.
The following message is currently displayed on
(...) [ 13.618079] mt7615e 0000:02:00.0: mediatek/mt7663pr2h.bin not found, switching to mediatek/mt7663pr2h_rebb.bin [ 13.758271] mt7615e 0000:02:00.0: HW/SW Version: 0x65322d31, Build Time: 19091404338b809 [ 13.758271] [ 14.013127] mt7615e 0000:02:00.0: N9 Firmware Version: 7663mp1827, Build Time: 20190914043434 (...)
For testing pourposes, I've downloaed from Linux Kernel Firmware GIT the following files:
And copied these to files to the device directory
/lib/firmware/mediatek/. After a reboot, the 5Ghz radio seems to be working fine, and the following messages are now displayed in
(...) [ 11.890146] mt7615e 0000:02:00.0: HW/SW Version: 0x65326363, Build Time: 2006030247debug [ 11.890146] [ 12.117059] mt7615e 0000:02:00.0: N9 Firmware Version: 3.1.1, Build Time: 20200604161656 (...)
It seems a newer firmware than the one included in the standar OpenWRT build.
Anyone could provide some insight if there is any advantage in using
mt7663_n9_v3.bin firmware instead of
mt7663pr2h_rebb.bin firmware with the MT7613BEN radio?
