Pipo M7pro - Cyanogenmod 11 (Android 4.4.4) porting

[fishpepper]

Sorry, I can't get adb working, my device is see as iddle or something like that (don't remember)
An can't get su working on tablet

When you try to connect with adb you should see a confirmation dialog on the sceen with the fingerprint. check always allow (or similar) and click ok.
The adb shell is started as root user.
(or you might have to enable adb debug in the developer settings before)

regarding the gcc 64bit et all,
its confirmed and justified here : https://groups.google.com/forum/#!to...ng/mYIMXU_DsrI



In the same site, someone said he has uploaded the 32 bit version of toolchain anyway, here :

https://github.com/boeboe/android_prebuilt_arm_toolchain_32bit

Installed it at the right location replacing the 64bit ones, then
rerun make clean (almost without error)

now trying brunch m7pro
but gives this error :



WTF !?
maybe this famous breakfast should have beeing run first, but how... ?

You need to synchro it after creating XML manifest by repo sync -c to get the files

Welcome aboard!

We definitely need more detailed how to (for 1st time builders), I have logged all the steps from my fresh linux install up to now in order to document for others, including where to run neach command from.
Please publish yours once you manage completely to buid, then to boot to cm.

@raxy
I don't have an m7pro to test but just wanted to see if I could make it through the build process before trying with m6pro but think it will be a bit out of my depth

I have tried on my M8HD, but I can't boot for now.

See what I have here : https://github.com/stevejcl/android_device_pipo_m8hd

What does does not boot mean? Not booting the kernel? Or no output showing up?
Its quite handy to connect an usb2serial converter to the debug pads on the main pcb. Then you get an in- and output from the beginning (you also see the bootloader stuff). The pads are clearly labeled RX, TX and GND on my M7pro (next to the power jack)

Usually you get a console even if the GUI bootup fails there... If you know how to solder or know someone who does: Grab an ttl-level Ftdi TTL-232R-3V3 (3.3Volt !) cable and connect rx,tx and gnd (swapped, rx from pipo goes to tx from ftdi cable). DO NOT USE A REAL RS232 Port/converter! (+/- 12V). Use a TTL one.
If you have some arduino serial converters then youo might have a 3,3V version between them.

I have nothing at all on the screen, even not the logo nor sound via usb on my PC.

So I think that my boot.img is not good.

Something has changed in fstab.rk30board.bootmode.emmc
M7Pro :

/dev/block/platform/emmc/by-name/system         /system             ext4      ro,noatime,nodiratime,noauto_da_alloc                    wait

M8HD:

/dev/block/platform/emmc/by-name/system         /system             ext4      ro,noatime,nodiratime,noauto_da_alloc,discard                    wait,resize

didn't test this for the moment

Don't want to solder for the moment, I have broken the LCD on my older M8Pro. it 's running but without anything on the screen only through HDMI !

Have a look at the boot.img (vim)
Your cm and the original version should start with KRNL
(did you run ./custom_boot.sh? this creates the boot image with that header)

Another thing: i think even with a broken boot.img i see the start image of my pipo. I do not see it if i flash a broken kernel.img - maybe thats your problem.

Restart the process this morning and I 've got an error while unpacking Rom from Pipo (M8HD rom)

So kernel.img was not unpacked !

Maybe need new Tools to unpack it, because I need to get new Tools to unpack this image under Windows, old version doen't work, even the FactoryTools made by Rockchip

@stevejc, thanks for the doc

I've studied it and the difference with my steps,

I had done this additional step, not present in your instructions :
git clone https://github.com/fishpepper/android_device_pipo_m7pro.git

and of course my workind directory is not ~/android /system

but unluckily, I still have explicit :

raxy@raxy-K8Upgrade-760GX:~/Documents/pipoCMkitchen$ brunch m7pro

including vendor/cm/vendorsetup.sh

device/pipo/m7pro/device_m7pro.mk:48: device/pipo/m7pro/proprietary_files.mk: No such file or directory

make: *** No rule to make target `device/pipo/m7pro/proprietary_files.mk'. Stop.

Device m7pro not found. Attempting to retrieve device repository from CyanogenMod Github (http://github.com/CyanogenMod).
Repository for m7pro not found in the CyanogenMod Github repository list. If this is in error, you may need to manually add it to your local_manifests/roomservice.xml.

** Don't have a product spec for: 'cm_m7pro'

** Do you have the right repo manifest?


No such item in brunch menu. Try 'breakfast'

device/pipo/m7pro/proprietary_files.mk
was effecttively missing after the repo -c sync;
but I've founf it in another folder resulting from my previous git clone; so copied it;
but brunch m7pro still give these errors :

ERROR: could not set PID 6694 to nice 1 - Permission denied

ERROR: could not set PID 6694 to nice 1 - Permission denied

ERROR: could not set PID 6694 to nice 1 - Permission denied

Is not using root the reason of this ?

[fishpepper]

go to device/pipo/m7pro after the repo sync and call
./fetch_prebuilts.sh
This will create prop...files.mk

the nice warning: a keyword to google for is schedtool, the android build system uses it to set the priorities. It can be configured somewhere.
