Searching testing people for hdmi + wifi in Kernel 4.16

Are the values printed calculated or defined…where is this done in code? Currently I can only print them

Also your datasheet is only for 16:9 aspect-ratio…the problems i have are mainly for 4:3 vga-resolutions (1024x768@60, 800x600@60, 640x480@60)…and 720p (where i don’t have any clue why my tv does not recognize signal)

I’ve tested 4.16-main, and I do not think any change is noticeable. Since it does not always occur, it is difficult to make a statement about it. It is noticeable when booting, or when the system is very busy. That’s why I suspect the power supply of the ssd.

Does the sata-error comes again with 4.16-main?

Occasionally yes. I had this error synonymous on other computer and it was always the power supply

Has anybody make a longtime-test and look if system is stable so far? As far as i see i can merge actual hdmi+wifi…some resolutions are not working yet,but a basic graphics-support is available…better than nothing

My longest system’s uptime was about 3 days, and always the reason was proper reboot. No hangs was all that time. Hdmi was OK(main resolution - 1920x1080). No wifi was tested - I still have no antenna.

@Ryder.Lee i mean this values for hsync-start and end:

mediatek-drm-hdmi 14015000.hdmi: hsync_start:1048,hsync_end:1184, htotal:1344

This seems no kHz value which should be near 48khz for 1024x768

Full log here Hdmi in uboot and linux

Please see my previous post: Searching testing people for hdmi + wifi in Kernel 4.16

Just wanted to chime in here. I updated the kernel on my device to your 2.4.16-hdmi + wifi branch; Sunday 6/10.

So far so good video seems to work its picking 1080 without passing any arguments. Looks good but I don’t have X installed so I am only using fbcon.

Wifi-driver is now merged to 4.18-rc1:

https://github.com/frank-w/BPI-R2-4.14/tree/4.18-wlan

it will be great if somebody can test it

wmt-tools including my script: https://drive.google.com/open?id=1MJxfHCpR-ph5YJu-_yMTCH5YG9rL6HHY

seems like there is anything missing again (crash on running wifi.sh):

This seems to be a hint:

[    0.771933] MTK-BTIF[E]_btif_set_default_setting(232):get register phy base from DTS fail

this problem is here:

drivers/misc/mediatek/btif/common/btif_plat.c:212     node = of_find_compatible_node(NULL, NULL, "mediatek,btif");

after change the compatible-string of btif-node (add “mediatek,btif”) i got this:

[    0.756544] MTK-BTIF[E]hal_btif_clk_get_and_prepare(285):[CCF]cannot get clk.

this depends on this line:

 drivers/misc/mediatek/btif/common/btif_plat.c:283         clk_btif = devm_clk_get(&pdev->dev, "btifc");

here i also fixed btif-node in dtsi:

clocks = <&pericfg CLK_PERI_BTIF>, <&pericfg CLK_PERI_AP_DMA>;
clock-names = "btifc", "apdmac";

both btif-problems can be also fixed in source (compatible-string “mediatek,btif” to “mediatek,mtk-btif” and clockname “btifc” to “main”)…maybe this is the better way, but finally i got the ap0-device:

seems like patching code instead of dtsi does not work or the additional clock “apdmac” is needed too

had to patch struct apbtif_of_ids[] in drivers/misc/mediatek/btif/common/mtk_btif.c too…now it works with default names (compatible/clock) of btif-node in mt7623.dtsi
