Blaze Tablet 2, Omap 4470 - Documentation needed.

Hello Tom,

The Blaze Tablet Platform Quick Start User Guide provides enough information to start with Blaze tablet development platform.

If you need Blaze tablet schematics, you should contact SVTRONICS http://www.svtronics.com/omap?product_id=15

I want to notice that we can provide their documents in the e2e forum.

However you can use the following links to obtain information how must configure the software release for this board:

Yanko,

Thanks for the reply.   As I said, I have the quickstart guide.  I have since been able to get the board operating using prebuilt binaries as well as my own.  The issue I am working on at the moment is the loading the of wireless drivers.  I am currently debugging this issue using information in the forums and  wiki. 

I had already contacted SVTRONICS and received the user guide.  I was also informed the additional documents listed in the user guide and schematics ( I think they are in the document I am looking for), I needed to contact TI and get them via a NDA.

The document I am looking for is:

 User manual ( DOC-21019 Blaze Platform HID) for the schematics , hardware, debug information and signals.

Thank you

Tom

Hello Tom,

Unfortunately, I cannot find such information - User manual (DOC-21019 Blaze Platform HID) for the schematics, hardware, debug information and signals.

I am using the information described in the wikis.

I want notice that it is possible to have issues with wi-fi module on Blaze Tablet.

If you use Android release for Blaze tablet, try to apply following:

Building Kernel Modules:

cd ${YOUR_PATH}/kernel/android-3.4
make ARCH=arm modules 2>&1 |tee ${MYDROID}/logs/kernel_modules.out

Building WLAN driver WiLink8

cd ${MYDROID}/hardware/ti/wlan/mac80211/compat_wl18xx
export KERNEL_DIR=${YOUR_PATH}/kernel/android-3.4
export KLIB=${KERNEL_DIR}
export KLIB_BUILD=${KERNEL_DIR}
make ARCH=arm

The above step will produce the following kernel WLAN modules: compat.ko, cfg80211.ko, 
mac80211.ko, wl18xx.ko, wlcore.ko, wl12xx.ko and wl18xx_sdio.ko. 
These modules are pushed into the /system/lib/modules directory on the flashed image.

shell@android:/system/lib/modules $ ls                                     
cfg80211.ko
compat.ko
gps_drv.ko
mac80211.ko
pvrsrvkm_sgx540_120.ko
pvrsrvkm_sgx544_112.ko
rproc_drm.ko
tf_driver.ko
wl12xx.ko
wl18xx.ko
wl7
wlcore.ko
wlcore_sdio.ko

Building WLAN driver WiLink7

cd ${MYDROID}/hardware/ti/wlan/mac80211/compat_wl12xx
export KERNEL_DIR=${YOUR_PATH}/kernel/android-3.4
export KLIB=${KERNEL_DIR}
export KLIB_BUILD=${KERNEL_DIR}
make ARCH=arm

To enable WI-Fi on Blaze tablet you must run a small script which is part of the build. Because Blaze table supports
WiLink7.

# su
# wilink7.sh

Could you provide us information about your issues with Wi-Fi modules on your Blaze?
You can send us a log file with issues.

I want to notice, that your problem can be caused by Hardware. 

More information about Wi-Fi you can see in: http://wireless.kernel.org/en/users/Drivers/wl12xx

Yanko,

I have a question on the expansion port 1 - Mobility Connector:   The link referenced for information on TI modules and features is dead:

Hello Tom,

About your question:

Are other modules available such as the WLAN to connect to the cellular network ( note SIM slot on board)?

See section 4.2 Selected Internal Features and Functions in your Tablet Quick Start guide:
Internal Features and Functions
Polymer Li Ion – 4150mAh
Lithium Battery Pack
Power Control System
Battery Emulator
Power Supply Subsystem
MODEM System
Modem System (Power, Connections, USB)
Vibrator Motors
2 Motors
Multimedia SIM Card Cage
Dual voltage (1.8/3/0V) SIM cage.
Internal SD/MMC Card Cage 8-bit, 3.0V dual function port.
Expansion Port 1
Warm Reset Switch

About SIM card usage refer to - http://processors.wiki.ti.com/index.php/SmartCard_Implementation_on_OMAPL_PRU_-_Software_Users_Guide

http://processors.wiki.ti.com/index.php/SmartCard_Implementation_on_OMAPL_PRU_-_Design_Document#GPIO

See your board configuration in arm/mach-omap2/board-omap/ board-44xx-tablet.c or other blaze tablet files. If SIM card is enabled.

Hello ASWIN PP,

I would like note you that in our OMAP forums, we only support official TI's software releases (Android or Linux).

We cannot provide you any type of a support for Windows Embedded.

Please conntact Phytec, they provide Windows releases for OMAP - http://phytec.com/software/windows-embedded/

Best regards,

Yanko
