Telechips TCC892X/TCC893X Android 4.2.2 SDK Leaked

February 12th, 2014 Leave a comment Go to comments

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.

Telechips_TCC8935_make_menuconfigAfter 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.

kernel/arch/arm/configs$ ls tcc*
tcc8920st_defconfig          tcc8935st_dongle_single_defconfig
tcc8925st_dongle_defconfig   tcc8935st_upc_defconfig
tcc8925st_upc_defconfig      tcc8935st_upc_single_defconfig
tcc8925st_yj8925t_defconfig  tcc8935st_yj8935t_defconfig
tcc892x_defconfig            tcc8935st_yj8935t_single_defconfig
tcc8930st_defconfig          tcc893x_defconfig
tcc8930st_single_defconfig   tcc893x_single_defconfig
tcc8935st_dongle_defconfig

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):

#------------------------------------------------------------------
# Define board revision
# 0x6230 : STBM   /TCC8930 /DDR3 1024MB(32BIT) /None
# 0x7300 : YAOJIN /TCC8935 /DDR3 512MB (16BIT) /None
# 0x7310 : YAOJIN /TCC8935 /DDR3 1024MB (16BIT) /None
# 0x8310 : UPC    /TCC8935 /DDR3 1024MB(16BIT) /None
# 0x9300 : DONGLE /TCC8935 /DDR3 512MB (16BIT) /None

There are also several build options for Android:

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:
Telechips_TCC893X_DocumentationYou’ll also find tools and binaries in ./vendor/telechips/ directory.

    i just want ask a very silly question why would some one download the sdk and what would they do with it thanks

    @adem
    It’s only useful for programmers, if you want to configure and/or modify the Linux kernel differently from the default, customize Android firmware, etc…

    Hey, this means micro PCs using this chip? Can you tell from the SDK what kind of hardware they will have?

    @onebir
    I can just see UPC /TCC8935 /DDR3 1024MB(16BIT), but there must be more clues in the code.
    I guess micro PC could just be small STBs like the one I wrote about before yesterday. Hotach HTV003 – http://www.cnx-software.com/2014/02/10/50-hotach-htv003-android-media-player-is-powered-by-telechips-tcc8935-soc/

    There are reference to YAOJIN, and YJ8935 in the code. It should be related to YAO JIN Shenzhen http://www.yaojinkeji.com/products.asp. It seems there website is not up-to-date but they’ve made STB with DVB / ISDB support before.

    i bought it yesterday it cost me around $65 aus i hope its worth it for a dual core because i could have bout a mk908 for the same price or maybe cheaper. but then i bought because i don’t have this chip-set and it will be a first for me and i can check out video content and xbmc support.

    @rafael duarte

    for now i think if it work as it should it would be a very good android media box because for the price range it includes a Ethernet port. and given the lack of firmware and xbmc support that you get with allwinner products i think this android box should do good.

    but i will do a unboxing and a user experience video for you guys
