[Pipo-Project] M7Pro kernel

[rrileypm]

I just flashed 1.32.09 and wifi works on my tablet. Is there anything else I need to check?

[rrileypm]

I just checked GPS...it isn't working.

I compared the GPIO output between 1.32.07 kernel and stock kernel
there is a lot of differences

[d33]

maybe, some production batches of m7pro use different chip?

Version 1.32.10 built to address these issues (hopefully)!

Hi d33, The touchscreen does not work on 1.32.10 so I cannot test any further.

tgray could you produce a dmesg for me via adb?

[d33]

Without DMESG I'm guessing but ...

[tgray]

Hi d33, I have only just got adb working on my comp so I will do some dmesg for you tomorrow as I am off to bed. I will also try 1.32.11 and let you know if there is any problems. I did find that on 1.32.07 the BT worked to start with but then started to play up (not starting, not finding other BT devices that I have used before) but the GPS still works okay.

you both have lost me...I hope randy is still catching up

Flash the test kernels and post a DMESG

Here's my dmesg file with 1.32.11:

https://drive.google.com/file/d/0ByxbjJg99RBrMkhSSWMyUzZiX3c/view?usp=sharing

Screen rotation is off 90 degrees counterclockwise
Battery meter doesn't work. Shows 0% with a 100% charge
Touch Screen works
GPS is still disabled
Wifi and touch screen work fine.

I tried 1.32.10 but touch screen didn't work.

I'm off to work in the hospital all day/night....so I though I would at least try these two test kernels for you. Good luck!!!!!

[TriA]

1.32.10
No touchscreen and hell bunch of error messages in DMESG

1.32.11:
Touch OK
HDMI is OK
No Wi-Fi (it just doesn't allow to switch it on)
No battery status (0%)
No GPS
No BT (but I was able to delete previosly saved pairing with my phone, unlike all other 1.32.XX kernels)
Swapped axis (X <=> Y) of rotation sensor
Reversed brightness scale

dee,
regarding the pipo kernel tree in the m7p SDK,
I added a + to kernel_local_release in .config
but kernel.img still unbootable...

what did you do exactly to make it bootable ?
tks.
