I’ve been informed that an Android 4.2.2 SDK for Telechips TCC892x and the newer TCC893x (TCC8930, TCC8933, TCC8935) dual core SoCs has been leaked on the Internet. The file (v13.03_r1-tcc-android-4.2.2.tar.bz2) is a 2.7GB tarball, and appears to be a full SDK. You can download the file here if you are interested.
After extraction, there’s 6.7 GB of data in the following directories:
| 40M ./libcore | 5.8M ./docs | 31M ./ndk |
| 5.0M ./gdk | 1.2G ./frameworks | 324K ./pdk |
| 95M ./development | 18M ./bionic | 544M ./kernel |
| 228M ./device | 106M ./hardware | 24M ./bootable |
| 295M ./packages | 55M ./sdk | 151M ./cts |
| 2.4G ./prebuilts | 1.7G ./external | 40M ./dalvik |
| 9.1M ./system | 108K ./libnativehelper | 6.9M ./build |
| 104K ./abi | 47M ./vendor |
The linux kernel is based on Linux 3.1.10, and there are a few config files to choose from with configs forh HDMI TV dongles, micro PCs, STBs, and evaluation boards for TCC8930, TCC8935, TCC8920 and TCC8925.

YJ8925T boards supports HDMI and CVBS video output, UPC support HDMI only, and others support HDMI, CVBS, and component outputs.
You’ll also find a few details about the platforms in the bootloader (bootable/bootloader/lk/target/tcc8930st_evm/rules.mk):

There are also several build options for Android:
|
1 |
source build/envsetup.sh |
You can run lunch to find out which Telechips builds are available, and start the build.
|

lunch ... 16. full_m805_892x-eng 17. full_m805_893x-eng 18. full_tcc8920st-eng 19. full_tcc8920-eng 20. full_tcc8930st-eng 21. full_tcc893x-eng |
Run make -j10 to start the build.
full_tcc893x-eng fails to buid, and full_m805_893x-eng as well with the error:

frameworks/base/core/java/com/android/internal/widget/LockPatternUtils.java:1280: error 114: @deprecated tag with no explanatory comment DroidDoc took 137 sec. to write docs to out/target/common/docs/doc-comment-check make: *** [out/target/common/docs/doc-comment-check-timestamp] Error 45 |
Following instructions found @ https://community.freescale.com/thread/303944, you can just edit frameworks/base/core/java/com/android/internal/widget/LockPatternUtils.java, and remove line 1280 “* @deprecated”.
The build will go further, but stops with:

Checking API: checkapi-last frameworks/base/api/17.txt:21088: error 9: Removed public constructor SmsMessage() frameworks/base/api/17.txt:21089: error 9: Removed public method android.telephony.gsm.SmsMessage.calculateLength frameworks/base/api/17.txt:21090: error 9: Removed public method android.telephony.gsm.SmsMessage.calculateLength frameworks/base/api/17.txt:21091: error 9: Removed public method android.telephony.gsm.SmsMessage.createFromPdu |
You can remove the complete “SmsMessage” class in 17.txt, and run make update-api, before carrying on with, and hopefully completing, the build.
Documentation related to Telechips TCC893x SoCs is available in ./vendor/telechips/documents/common/pdf/ directory:
You’ll also find tools and binaries in ./vendor/telechips/ directory.
