ScoreABSM Posted June 21 Posted June 21 Context: new Banana Pi M4 zero (rev 2) is using Wifi/BT over SDIO, which requires an sdio overlay. Thanks to Armbian team for providing it. Editing armbianEnv.txt to add "overlays=bananapi-m4-sdio-wifi-bt" did the trick for Wifi but BT is still not available (neither in standard or rolling builds)... @c0rnelius I know you tried to figure out why, I'm missing technical knowledge to help... Digging the Internet I saw similar bluetooth issue for radxa zero 3w with aic8800, resolved using hciattach / hci up, but needing an available /dev/ttyS1 (UART1) we are missing here... Do you know why? Could it be the problem for banana pi m4 zero and if yes could an overlay activate it? Denis 0 Quote

If I add these two patches it breaks bluetooth on this kernel build. drv-rtc-sun6i-support-RTCs-without-external-LOSCs.patch drv-rtc-sun6i-Add-Allwinner-H616-support.patch I'm still investigating in my spare time, but I'm not 100% on anything. Could be I need to take another approach to the bluetooth node in Armbian? So this is where am at. If anyone has any thoughts I'm all ears. 0 Quote

ScoreABSM Posted July 5 Author Posted July 5 Many thanks @c0rnelius! Is there a build available to test these patches for bluetooth? Upgrading from 25.2.2 Debian standard image or only in rolling (Trixie or Plunkie)? Denis 0 Quote
c0rnelius Posted July 5 Posted July 5 @ScoreABSM Sorry I had to revert that PR. It seemed to initially work, but in the end it started hitting fails more than it functioned. https://github.com/armbian/build/pull/8344 I'm still on the case. 0 Quote
c0rnelius Posted July 6 Posted July 6 The issue appears to be two things. These two patches and the current defconfig(s) being used. drv-rtc-sun6i-support-RTCs-without-external-LOSCs.patch drv-rtc-sun6i-Add-Allwinner-H616-support.patch When I disable those patches and use my own defconfig everything works as it should. https://paste.armbian.com/tixixocubu The hard part here would be figuring out exactly what in the defconfig(s) are either breaking things or missing. Also if I disable those patches, what does it break on other units? I'm under the impression these patches were rejects from the original h616 bring up in mainline. But I could be wrong? 1 Quote

ScoreABSM Posted Tuesday at 10:05 PM Author Posted Tuesday at 10:05 PM Hi @c0rnelius, Sorry I was not clear enough, could you share with me an image to test including BT (the 2 patches removed and using your own defconfig)? Denis 0 Quote

ScoreABSM Posted 5 hours ago Author Posted 5 hours ago Hi @c0rnelius, I did some tests with your image, connecting bluetooth audio earbuds, installing XFCE, chromium,... it works (and also wifi, hdmi/audio, ...)!! But some problems (side effects of disabling the 2 patches?) : - hdmi audio (working fine despite the following errors) "hdmi-audio-codec hdmi-audio-codec.5.auto: Only one simultaneous stream supported! "hdmi-audio-codec hdmi-audio-codec.5.auto: ASoC: error at snd_soc_dai_startup on i2s-hifi: -22 - i2s (despite I don't use it, following error in log) "ahub_plat-i2s-hifi: ASoC: error at __soc_pcm_open on ahub_plat-i2s-hifi: -22" - WiFi (working fine despite the following errors) "brcmfmac: brcmf_set_channel: set chanspec 0x100e fail, reason -52" "brcmf_p2p_send_action_frame: Unknown Frame: category 0xa, action 0x8" - display lags / windows repaint problems, seems to appear only after using GPU to decode videos, following errors in log) panfrost 1800000.gpu: gpu sched timeout, js=0, config=0x7300, status=0x8, head=0x10061d80, tail=0x10061d80, sch$ panfrost 1800000.gpu: Panfrost Dump: BO has no sgt, cannot dump panfrost 1800000.gpu: gpu soft reset timed out, attempting hard reset panfrost 1800000.gpu: gpu hard reset timed out panfrost 1800000.gpu: error powering up gpu L2 panfrost 1800000.gpu: error powering up gpu shader panfrost 1800000.gpu: error powering up gpu tiler panfrost 1800000.gpu: gpu sched timeout, js=0, config=0x7300, status=0x8, head=0xd0bd0c0, tail=0xd0bd0c0, sched$ panfrost 1800000.gpu: gpu sched timeout, js=0, config=0x7b00, status=0x8, head=0x11195d80, tail=0x11195d80, sch$ This last one is the main problem. Also strange GPU is activated without adding gpu to overlays... Hope this helps. Denis - dmesg.txt armbianEnv.txt 0 Quote
Solution c0rnelius Posted 1 hour ago Solution Posted 1 hour ago @ScoreABSM I have no clue what the HDMI audio errors are in the dmesg. I noticed them before as well. I know mainline doesn't actually have HDMI audio support yet. I'm not sure where these HDMI audio patches originated, but I assume the OrangePI repo. Of course, I could just be doing something wrong here on a DTS level? Strange your getting chanspec errors. This was resolved on my end by updating the wireless-regdb. You can try resolving it with this: "Put in your COUNTRYCODE" extraargs=cfg80211.ieee80211_regdom=US or this echo "options cfg80211 ieee80211_regdom=US" > /etc/modprobe.d/cfg80211.conf I'll disable the gpu by default. No. I don't see how removing those RTC patches would be creating these errors. The chanspec one is well known. Also happens on RPI's. I have a HACK patch that disables the error, but thats not really a fix. When I ran tests with the GPU before I never saw those errors and that GPU patch was pulled from mainline. I believe? Pretty sure it is the same patch I use in my personal builds. II'll say this. This is becoming endless. I'm getting ready to toss this SBC in the garbage 0 Quote
c0rnelius Posted 28 minutes ago Posted 28 minutes ago @ScoreABSM https://github.com/armbian/build/pull/8394 I enabled gpu via overlay. Looking fine on my end. Tested using Chromium and Youtube. Still not sure about that audio dmesg error. Audio does work though. Image I ran test with: https://github.com/pyavitz/binary/releases/download/images/Armbian-unofficial_25.08.0-trunk_Bananapim4zero_bookworm_current_6.12.35_xfce_desktop.img.xz dmesgandmisc.txt 0 Quote
