[BPI-R64] OpenWRT kernel 5.4.40 running from eMMC

Both mt7622 and mt7615 are loaded correctly and run smoothly on my board.

MT7622 onboard WiFi actually shares the same firmware download procedure with BT. However, the driver currently lacks of mechanism to sync both components that cross the subsystem. Try to disable btif node in dts to keep them mutually exclusive for the moment. Will fix it in spare time.

More specifically, you may need to apply this patch to get BT work. https://patchwork.kernel.org/patch/11504383/

And just for clarification, you are using Openwrt Image generated with steps from first post?

Hi. Yes, I followed the steps exactly as enumerated in post #1. Thus after the build, I am copying the files build_dir/target-aarch64_cortex-a53_musl/linux-mediatek_mt7622/{bpi_bananapi-r64-kernel.bin,image-mt7622-bananapi-bpi-r64.dtb,root.ext4} to r64-boot on the SDcard and mounting the SDcard as /media/sdb1 on R64 and running update.sh to flash to eMMC.

From @niebieski20 and @Ryder.Lee responses, it is not clear if mt7622 is not releasing the semaphore or if BTIF is causing the problem.

In either case, I would like to try to disable both: mt67622-onboard-wifi and btif and enable only the mt7615. How do I do that? I guess I need to edit one or both: mt7622-bananapi-bpi-r64.dts or mt7622.dtsi files.

To respond to earlier messages: my experience is the same as @svintuss as far as the patch semaphore timedout is concerned. Actually, I sometimes get a kernel crash from the mt7615 driver too – but I don’t want to distract this thread. Here is my bootlog (note: there are some extra messages showing from additional dev_info() messages I added into the driver code)

I too see that the mt7622 wifi firmware gets loaded and I can get full network functionality from it (802.11n). But mt7615 driver does not get to the point of loading firmware.

@Ryder.Lee, I do have

&wmac {
	status = "okay";
};

in the mt7622-bananapi-bpi-r64.dts file.

In mt7622.dtsi file, the btif node is:

btif: serial@1100c000 {
		compatible = "mediatek,mt7622-btif",
			     "mediatek,mtk-btif";
		reg = <0 0x1100c000 0 0x1000>;
		interrupts = <GIC_SPI 90 IRQ_TYPE_LEVEL_LOW>;
		clocks = <&pericfg CLK_PERI_BTIF_PD>;
		clock-names = "main";
		reg-shift = <2>;
		reg-io-width = <4>;
		status = "disabled";

		bluetooth {
			compatible = "mediatek,mt7622-bluetooth";
			power-domains = <&scpsys MT7622_POWER_DOMAIN_WB>;
			clocks = <&clk25m>;
			clock-names = "ref";
		};
	};

status = “disabled”; – does this mean BTIF is already disabled?

BTIF is another problem to enable both BT and onbaord WiFi. I guess this is a board issue since I saw mcu timeout from your log.

btw I saw this patch has applied into openwrt trunk, so no need to apply extra patch for BT

I just clarified that you can run both MT7615 and MT7622 simultaneously. I didn’t see any problems to share the same driver here, but actually I used mt7622-rfb not bpi-r64.

I guess it’s just R64 board issue, so please ask BPI team @sinovoip for help.

Same issue with OpenWRT + 4.19. Not surprising, because I’m building openwrt from sources and it builds mt76 using latest source from github.

Can you tell which version of mt76 you’re using, or approximate build date, so I can find it in git?

can you provide mac80211 debug logs? did you guys have this fixup in your tree? i suspect this is root cause for your problems - “then clients stops connecting until reboot”.

thx for your solution!!!

i successfully boot BPI-R64 on kernel 5.4

but i found some iusse

1),the mpcie not work,and i think the official DTS file has null declaration

2), i try build-in wifi ,but i can’t successfully boot it

at lasted thx for your contribution

i try build-in wifi ,but i can’t successfully boot it

&btif {
        status = "okay";
};

Please check your dts file and set status = “disabled”;

have you applied mpcie-patches (splitting+irq-handling) for r64?

this is basicly for google-cards, but also pcie-related:

for bluetooth i have also this in my tree:

and just for explaination: the mt7622.dtsi defines nodes for SOC-level and will be overlayed by board-specific dts…like mt7622*-r64.dts, there are some nodes enabled and partially some additional content added (like pinctl-definitions)

Yes it was applied from beginning. I also try mt76 from yesterday but problem still exist

thx for your help

it works !!!

now, when i run on 40Mhz

it can’t seem to connect to the Internet

online network IMG_825555693350-1

local network

Please tell me how to activate SATA in this firmware?

I agree with @Kosyak. I get the same behavior with kernel 4.19.115: onboard wifi works, but pcie mt7615 fails to acquire the semaphore and thus does not reach up to loading firmware.

So I am continuing to stay with kernel 5.4 experiment.

@frank-w, I do see the mt7622 onboard wifi get and release the semaphore before mt7615 attempts to get it. Here is output of

dmesg|grep 76

(I added a debug message in mt7615/mcu.c mt7615_mcu_patch_sem_ctrl function)

How can I disable the mt7622 onboard wifi in the DTS? If the mt7615 gets working, I don’t see a need for the onboard wifi.

The linux-5.4.40/arch/arm64/boot/dts/mediatek/mt7622.dtsi file contains this:

wmac: wmac@18000000 {
	compatible = "mediatek,mt7622-wmac";
	reg = <0 0x18000000 0 0x100000>;
	interrupts = <GIC_SPI 211 IRQ_TYPE_LEVEL_LOW>;

	mediatek,infracfg = <&infracfg>;
	status = "disabled";

	power-domains = <&scpsys MT7622_POWER_DOMAIN_WB>;
};

And in mt7622-bananapi-bpi-r64.dts, it is overlaid with

&wmac {
	status = "okay";
};

By removing the wmac status=“okay” overlay, will that disable only the on-board wifi, and still try to initialize the mt7615? Or is enabling the wmac necessary for mt7615?

just disable the wmac-node like the btif above :slight_smile:

I’ve recorded trace during connection attempts using trace-cmd record -e mt76 -e mac80211 https://drive.google.com/drive/folders/17kKnUi9nhBDna_mg0xK_CkPFoJjim6Nf?usp=sharing

latest mt76 driver, client MAC: 60:67:20:48:4b:f8, -good trace - successful connection after R64 startup, -bad - failed (with “authentication timed out”) connection after ~1 hour.

Hope this will help.

P.S. Also, got this when tried to unload mt7615e:

The unloaded problem should be fixed and we’re running 1h+ iperf now and mt7622 seems stable. Please update your mt76 driver to the latest one.

I kept btif and wmac nodes disabled by commenting out those nodes from the mt7622-bananapi-bpi-r64.dts like this:

/* &wmac{
       status = "okay";
}; */
/* &wmac{
       status = "okay";
}; */

Both are inherently disabled in the mt7622.dsi.

I can see that mt7622 onboard wifi driver does not get activated, nor does BT. However, I still see mt7615 failing to get the patch semaphore

I am going to try the spit pcie-nodes and other patches mentioned by @frank-w in post #31 I think that might hold some promise, because, when I compared the bootlog from the LEDE version of @sinovoip (http://wiki.banana-pi.org/BPI-R64_%2B_MT7615_function_test), I see it accesses addresses 1a143000 and 1a145000.

But in my openwrt with kernel 5.4.40, it accesses only 1a140000

I see that @frank-w patch for the split pcie-nodes seems more aligned with the boot log of BPI mt7615 function test.
