i open a new thread about the driver support for the bpi wifi7 card for r4…
bpi source is not compilable by me, also tried mapping the mt76 code with bpi patches into a newer kernel…so the mt76 repo is only for reference (easier than looking through a bunch of patches)
my current state is that i can load the right firmware with mainline-kernel, but i only see 2 interfaces (2.4G and 6G…5GHz is missing).
at least with the right firmware there are no more message timeouts flooding the console
any help is welcome maybe anyone knows why i only see 2 phy
Is it possible that, like the 7916, the 6ghz and 5ghz share the same phy? Have you double checked that the reg domain allows 5ghz where it’s set at? I remember another card having a safety measure where it didn’t allow the 5ghz and 6ghz at the same time, maybe the ax210?
tried up2date openwrt from source and replaced firmware with the 233 variant…there i do not see the trace,but get message timeouts after enabling the wifi in /etc/config/wireless and restarting it (/etc/init.d/network restart) and do only see 1 phy

after a reboot it looks better, but not perfect

thats what i try now and i see 3 interfaces now

but all bring a warning in mac80211, when i try to set them up
WARNING: CPU: 2 PID: 3234 at net/mac80211/main.c:270 ieee80211_hw_conf_init+0x128/0x130 [mac80211]
in downstream this was added to mt7996_config (main.c)
if (changed & IEEE80211_CONF_CHANGE_CHANNEL) {
+ if (!mt76_testmode_enabled(phy->mt76) && !phy->mt76->test.bf_en) {
+ ret = mt7996_mcu_edcca_enable(phy, true);
+ if (ret)
+ return ret;
+ }
this function is only in downstream, but i do not understand what exactly it does (looks like some checks for reg-domain)…added it with all depencies i found, but still the warning…
it looks like the warning is caused by the mt7996_mcu_set_txpower_sku call in mt7996_config…
Current state is that it looks like that the special firmware for the module (_233) is not compatible with mainline code…contacted mtk (person who upstreamed current firmware)
maybe anyone knows why i only see 2 phy
and i see 3 interfaces now
