    ROOT TUTORIAL And Market fix:

    How to root the CX-01 and how to fix the market issue.

    rooting is very simple, note: im using windows xp.

    DOWNLOAD: http://www.sendspace.com/file/nshpmj

    1 - Uncompresse the cx-01.zip file into your pc.
    2 - Connect the cx-01 into your pc. Wait some minutes until it finishes to "boot". In the pc will show you that will need to install a driver.
    3 - When the installation driver screen appears, select advanced option to select the folder driver from the file that you have already uncompressed it.
    4 - when finished installed the driver go to the folder Root-Script
    5 - run Root-Script.bat

    Root-Script.bat
    a - Select option 1 and verify the connection if OK
    b- Select option 2 and check if your device can be rooted (with this script)
    c - if its ok select option 3 when finished the CX-01 will be rebooted.

    Fix Market issue:
    1 - Rename the file Google_Play_3.5.15.apk that is already provided in the ZIP into vending.apk
    2 - copy vending.apk file into /system/app/
    3 - Then install it.

    note: To copy this you need the es explorer configured as root. then you will be able to copy it.

    reboot the device an you will have it rooted and with the market fixed. Update all your applications.


    I dont know yet but i may be doing a script that fixes some bugs and roots the tablet all in one click or something like that, but that takes time and work. also im still waiting the original rom so i can tweak it better i don't want brick the cx-01. Next quick update will be full market. but untill i dont get a full signed firmware. i will not be working on any thing that can brick the tablet.

    Good luck

    source: cx-01 | CNXSoft – Embedded Software Development


    Yesterday, we got Linux kernel 3.0.8 source code from Telechips, as well as some files related to Android 4.0 (Webkit + OMX). Today, I’ve had a look at the kernel source code and found a few very interesting things.

    Read more: cx-01 | CNXSoft – Embedded Software Development


    First let’s get the code from github:

    git clone git://github.com/cnxsoft/telechips-linux.git
    Good news! The code for the latest Telechips TCC892X is present in arch/arm/mach-tcc892x, and there is support for 3 types of boards:

    board-m805_892x – TCC8923 M805 board
    board-tcc8920 – TCC8920 evaluation board
    board-tcc8920st – TCC8920 STB evaluation board

    TCC8920 STB evaluation board appears to be relevant to products such as Diyomate A6, but if it’s also used for TCC8925 HDMI Dongle such as CX-01 mini PC, Zero Devices Z900 or ValuePlus TizzBird N1.

    Now let’s have a look at the default config directory for arm (arch/arm/configs):

    ls | grep tcc89
    tcc8920st_defconfig
    tcc8920st_hdb892s_defconfig
    tcc8925st_dongle_defconfig
    tcc8925st_donglehs_defconfig
    tcc8925st_hdb892f_defconfig
    tcc8925st_isdbt_module_defconfig
    tcc892x_defconfig
    Nice! tcc8925st_dongle_defconfig and tcc8925st_donglehs_defconfig look particularly interesting!

    Read more: cx-01 | CNXSoft – Embedded Software Development



    A quick comparison shows that the only difference is that tcc8925st_donglehs_defconfig sets CONFIG_HDMI_DONGLE_CLOCK_HIGH_SPEED=y.

    Looking further in the source code:
    #define TCC_CPU_FREQ_HIGH_SPEED 812500
    #define TCC_CPU_FREQ_NORMAL_SPEED 716500
    So tcc8925st_dongle_defconfig configuration file sets TCC8925 to run at 716.5 MHz and tcc8925st_donglehs_defconfig to 812.5 MHz.

    The kernel configuration enables the Android stuff, so it’s probably the kernel we’ve got in the device running Android. Let’s try to build the kernel with TCC8925 clocked at 812.5 Mhz (High Speed config) assuming you’ve got the ARM toolchain already installed (run apt-get install gcc-arm-linux-gnueabihf in Ubuntu, if you don’t):

    make ARCH=arm tcc8925st_donglehs_defconfig
    make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j2 uImage
    ....
    Image Name: Linux-3.0.8+
    Created: Wed Jul 18 20:22:07 2012
    Image Type: ARM Linux Kernel Image (uncompressed)
    Data Size: 3136392 Bytes = 3062.88 kB = 2.99 MB
    Load Address: 10008000
    Entry Point: 10008000
    Image arch/arm/boot/uImage is ready
    Good! It can build! We now have got the kernel (zImage and uImage) in arch/arm/boot. Let’s build the kernel modules:

    make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j2 uImage INSTALL_MOD_PATH=build_modules modules
    make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j2 uImage INSTALL_MOD_PATH=build_modules
    modules_install
    The kernel modules are located in build_modules directory. There are only 2 kernel modules: gspca_main.ko (video driver) and scsi_wait_scan.ko.

    I cannot give it a try now, as I haven’t received the hardware yet. The other thing I would like to get before hacking CX-01 mini PC is a recovery firmware, and the eventual tools to recover the device when something bad happens. I’ve contacted PandaWill to try to get it. The bootloader code would also be nice, but not an absolute must. However, I believe it’s unlikely we’ll get the bootloader source code since Telechips does not appear to have released it for the older versions of its TCC processors.

    Telechips Releases Linux Kernel 3.0.8 and Android ICS Source Code

    lechips has just uploaded the GPL source code for kernel 3.0.8 and Android 4.0 to the open source section of their website.

    If downloading from telechips website is too slow, you can also try alternate downloads (Thanks Gabe!):

    Kernel-3.0.8.tar.gz linux files - Kernel-3.0.8.tar.gz - Minus
    Ics.tar.gz linux files - Ics.tar.gz - Minus

    I’ve also created 2 repositories in github:

    telechips-linux – Linux kernel source code https://github.com/cnxsoft/telechips-linux
    telechips-android – Android platform open source code (webkit + OpenMAX source code) https://github.com/cnxsoft/telechips-android

    It haven’t looked into the source code in details yet, but hopefully, this will allow developers to customize the firmware running on Telechips TCC8925 based mini PCs such as CX-01 mini Android TV Box or Zero Devices Z900.

    Thanks for the posts, alot of useful info.

    i have seen this device online but never tested my self. I wonder how it compares to the MK802, looks little slower on paper
    How is the video playback on this device, both streaming and from file?

    Its great too see that they released the source code, we should see some customs roms.


    It looks like its time for a subforum for the CX-01.

    The device works very well. the A5 for what i have read is between a cortex a8 and a9 but has low power consumption. the cpu is set into 800mhz and not 1ghz or 1.5ghz like in some sites is published. it does not get hot like an a10 chipset.

    The partition on the 4gb are divided into 2 partition of 2gb each one.

    1 - i did playback for 720moves i did no have any issue.
    2 - also did used the device with netflix and did work perfect.
    3 - also did installed imediashare for upnp client / server device and did work perfect sharing photos or music from a celphone.
    4 - ted talk (video streming) works perfect.
    5 - youtube app works ok too.

    so the video playback is not an issue. the interface feels very good. and the firmware need some tweaking but is not an ugly firmware id dose the basic things you need. it can be improved and im working on it.

    i have all ready published how to root the device.

    i have developed a script put not published yet to:
    a - Installing Stable Android Market
    b - Installing FullMarket and other build.prop Tweaks
    c - Installing Ads Blocks /system/etc/hosts
    d - Google blocking apps writing to SD cards (fix)

    by the moment i need some feedback from the users so i can add more stuff there and publish it.

    It seems that there are similar devices like the CX-01 like c77 or other basically all are the same but the sometime have some different issues in the firmware. i was told in some devices you can use adb because usb debug is not enable and you cant access to the .development menu due it is not shown.

    so to show the development settings menu install a terminal emulator en the device and type the following line. it will bring up the development menu.

    Code:
    am start -a android.intent.action.MAIN -n com.android.settings/.DevelopmentSettings
    there in that menu enable the USB debug option and you are ready to flash the device.
