[Pipo-Project] M7Pro kernel

[TriA]

1.32.5 - much better!
only the very first step of brightness scale is black screen, the rest are ok
Auto brightness is ok too

By the way, I've found one more missing feature in this kernel: HDMI support !

[TriA]

I've found a way to control brightness via ADB:
adb shell "echo 255 > /sys/devices/platform/rk29_backlight/backlight/rk28_bl/brightness"
use 255 for maximum
12 for minimum
0-11 are black screen

Post up a DMESG from 1.32.5 and one from stock please

[TriA]

done

[d33]

Thanks - looks like a GPIO conflict on GPIO1-B5 (205). Possibly fixed?
I also increased the minimum brightness to 50

[TriA]

1.32.6
Brightness: excellent
HDMI: excellent
BT: not yet

GPS doesn't work ?! (at least no satellites for 10 minutes under the open sky)

[d33]

Well, all looks okay with BT in code and I thought we had people reporting working GPS

I've tidied up a bit of code on board initialization that may help but nothing stands out. Can you provide GPIO dumps?

[raxy]

here are dumps from fazerg, some tiem ago...

From my kernel

Hi d33, Just checked out 1.32.07. GPS works for me and BT file transfers work. The only thing I cannot get to work is the internet access using BT. As soon as you switch it on it switches itself off. Sorry for taking so long to test but we have had a few power failures here (last 1 today for 5 hours). The brightness control works great.

[d33]

Can you test this one too? I've been messing with the code to make it work for all kernels and want to ensure it still works for M7 Pro

[tgray]

dee, I will test it later today as I have to go to work shortly and let you know if I found any problems.

FIrst problem I have found is that the wifi doesn't work when I turn it on.

[TriA]

Here are some GPIO dumps from 1.32.07
BT is non-functional
GPS seems to be on, but it wasn't able to find any satellites

GPS was ok with 1.32.3, but there was no HDMI


I tried 1.32.08, but Wi-Fi doesn't work with this kernel

[d33]

Bugger, wifi dead on 1.32.08 ... ok, try this one and give me a DMESG of this kernel if it doesn't work properly

[edit] Actually just realised that this is strange:

tgray "Just checked out 1.32.07. GPS works for me and BT file transfers work. The only thing I cannot get to work is the internet access using BT"
TriA "Here are some GPIO dumps from 1.32.07. BT is non-functional. GPS seems to be on, but it wasn't able to find any satellites"

You can't both be right!

[TriA]

1.32.09 - wifi not working. I attached the dmesg log

You can't both be right!

Why not? I wrote

AMPAC's chip AM6476 (WiFi + GPS + BT), which is installed in M7pro, is a combo of Broadcom BCM43362 (WiFi + SDIOv2) + Broadcom BCM2076 (GPS/Glonass + BT + FMradio)

maybe, some production batches of m7pro use different chip?
