Hey there!

I have just received a vivo, and I would like to develop for it. The phone's specs state that vivo is msm8255, but when I look into the device tree of the phone, the ROMs use msm7x30 platform. Can someone please explain this to me?

Also, does anyone know the name of chips in vivo. This is a very hard thing to find. For example, the bluetooth is BCM4329.
If no one has this information then it is alright, but I would like to my first question answered.

Thank You. :good:

You should PM Szeszo on this stuff. He is our main developer and has been pretty much our only developer for almost half a year now. He knows this device inside out :)

100% same chipset as the 7x30 devices, our 8255 is essentially an overclocked 7x30 like on desire z
That's why desire z has same chipset as us

Bcm 4329 is WiFi too, but bcmdhd is used for AOSP and sense 4 which is ported from One V or latest prima

Wikipedia has some good information

Why is it so important? :) As poondog said, our CPU just an msm7x30 on higher clock. But we have that CPU's board name, why? Qualcomm knows... Like the MSM8225 and MSM8625Q (dual and quad-core Cortex-A5 CPUs) has msm7x27a board names. Why? Qualcomm knows...

This is off topic, but...

Yes, Adelaide is a boring city. Nothing here to look at (can only look at myself in the mirror) :(
But what I do like about Adelaide is that it is a planned city; it is very hard to get lost here (even if someone tells you to get lost). When I went to Sydney, I got lost, because the roads aren't straight forward. I've also visited Melbourne, but I didn't like it, because the city there is too tight; the roads are very small, and the trams on the road take up too much space. But Melbourne kind of reminds me of my home country (Pakistan).

By the way, I do know somewhat about kernel development. I have tried to port a 3.4 kernel to a previous device, and I got the kernel to boot, but I coudn't get the ROM to boot. The phone died really quickly and now I cannot fully port the 3.4 kernel to it anymore, however someone else with the same device has already ported it, and I know how he did it. So, I am going to try it with vivo. But, I won't gurantee success.

Yeah haha fair enough it's boring :)
@szezso has tried but there are like no similar devices with a working 3.4.Y kernel so it's a bit hard.. working with like only one similar 3.4.Y device haha
