[Pipo-Project] M7Pro kernel

hmm, what is CIF...

And regarding Wi-Fi voltages:
Wi-Fi/BT chip AP6476 requires 3 voltages:
VBAT (Input supply Voltage): min. 3.0V, typ. 3.6V, max 4.8V
WL_VIO (Voltage source for WiFi SDIO I/O Voltage): min. 1.7V, typ. 3.3V, max 3.6V
BT_VIO (Voltage source for WiFi & Bluetooth GPIO/UART I/O Voltage): min. 1.7V, typ. 1.8V, max 1.92V

aaand...
with 1.34.13 I have BT and GPS WORKING after a power cycle.
Maybe, voltage was just set too high for them to work, in all previous 1.34 builds?
but, BT and GPS still aren't working after a soft reboot.

[JohnThomson]

Hello d33, screen is now correct, thanks for that. BT will not start.
GPS has constant error messages concerning IPC, ie "waiting for.."
"communication error", "IPC connection closed by peer", also some debug info
concerning Glgps, also SIGABRT in Glgps. I got this from Catlog, if I knew how I
could post it if it's of any interest.
Kind regards, John

[TriA]

Try to power off / power on the tablet, I wonder whether the BT will work after that? I mean 1.34.13 build.
Regarding Catlog - you can attach the file to the message

[JohnThomson]

Hello TriA, BT works after a hard power off/on, GPS still not.
Here is part of the Catlog output regarding GPS.
I do notice that the little antenna symbol in GPS Status does sometimes come
on for a very few seconds when I start it.

JohnThomson
something is wrong there...
here is the crash report of gps process :

Fatal signal 6 (SIGABRT), thread 173 (glgps)

I have no such lines in my catlog

[JohnThomson]

Clearly there is some major problem with my setup. I am on Rileyrom 3.4 + v1.34.13.
I start to suspect something not right in my gpsconfig.xml, but it should be the same
as your's.

[d33]

aaand...
with 1.34.13 I have BT and GPS WORKING after a power cycle.
Maybe, voltage was just set too high for them to work, in all previous 1.34 builds?
but, BT and GPS still aren't working after a soft reboot.

Don't soft reboot

[TriA]

... and then it's definately done :-D

[TriA]

1.34.14
Camera flash still isn't available...


And I afraid what fast battery drain is returned with 1.34.13
Just like 1.32.* series:

Oh dear. Is it related to GPS working? 32.17 had a newly working GPS, so does 34.13

[TriA]

maybe, the GPS is always powered now, regardless of its setting selected in the "location" menu?
I'll test different cases (with GPS on, off, and with non-working state after soft reboot) and will report later

[tgray]

Hi D33 & TriA,

I have checked 1.34.14 and everything is good except the camera flash. Also I did notice that the compass is now 90 degrees clockwise out (east is showing north). I went back to 1.32.07 and the compass was okay.

I'll fix the camera & the compass - what about battery consumption though?
