Question pi
I have a raspberry pi with BCM cpu

some people have ported CM to it but its very slow, so not many devs are interested.

it was pointed out that SGC and raspi are similar to some degree and some code is useful for both hw platforms.

do you think a synergy is possible between both devices ?

The cm12 branch is not functional because we never managed to fix ARMv6 support for the ART runtime. We merged all incomplete patches that were present on Jenkins before shutting the server down completely, so it was left in a big mess. Please don't ask for further help on this - I can't provide any.

Some suggestions for working on BCM21553 Roms(cooperve, totoro, tassve)
Hi,
I wanted to know if there is anyone working/willing to work on BCM21553 roms? I'm not an android dev but I researched about BCM21553 phones and I found some info regarding fixing the issues with CM ports of these devices:

- CM9 audio issue
these are commits developed by Conn(psyke83 +, +) which solved audio routing in cm11 (Conn came up with them after Biel +, + had stopped development of CM9 and I thought applying them to CM9 tree might solve the issue):
commit1: https://github.com/broadcomCM/androi...412449d7315cd1
commit2: https://github.com/broadcomCM/androi...23e674cb666079
commit3: https://github.com/androidarmv6/andr...167aa04d42b5f7
commit4: https://github.com/androidarmv6/andr...e6dbbe78a9dca6
commit5: https://github.com/androidarmv6/andr...c88a9d109daaa2
commit6: https://github.com/androidarmv6/andr...6fc92cf5254805
You'd better apply these step by step and compile for simpler debugging of potential compile errors.

- CM9/CM11 OMX codecs(Video Recording Issue might be an effect of this issue)
I did a research to find out similar phones to ours which have a working port of CM and I found Samsung Galaxy S II Plus + ,+ , + which has the exact same GPU(VideoCore IV) and almost same Broadcom chipset(although not the exact BCM21553). I thought getting it's codec blobs(from here) and applying the following patch might lead to working hardware codecs.
The patch: https://gist.github.com/pawitp/7945188
we might need reverting the following commit for the above to work: https://github.com/broadcomCM/androi...384945a89db330

- CM9 USB Tethering
The fix seems to be already in CM9 device tree but it didn't get compiled by biel!(CM9 device tree updated after the last BETA5 build)
relevant commit

- CM9/CM11 Torch
Again comparing with GS2 plus I came up with following potential solution:
commit1: https://github.com/SamsungBCM-Cyanog...2b9c9bf65035f8
commit2: https://github.com/SamsungBCM-Cyanog...f8de5996b40791

So basically,which kernel/device/vendor source shall I use to compile the ROM?

I think you should begin at these places:
cm9: https://github.com/broadcomCM/local_manifest/tree/ics (look at local_manifest.xml)
cm11: https://github.com/androidarmv6

cm11 kernel, device, vendor: https://github.com/androidarmv6/android_kernel_samsung_bcm21553-common, https://github.com/androidarmv6/android_device_samsung_cooperve, https://github.com/androidarmv6/android_vendor_samsung
