bc10/rowboat
Summary †
DSP stack has been added to rowboat-eclair-dsp so far. This section is working to integrate SGX and SGX SDK with
rowboat-sclair-dsp. This section is based upon this page and follows its direction.
SGX and DSP integration. SGX †
OMAP35x_Android_Graphics_SDK †
Execute the installer, and Install OMAP35x_Android_Graphics_SDK
$ cd ti_android_sgx_sdk
$ ./OMAP35x_Android_Graphics_SDK_setuplinux_3_01_00_03.bin
As the installer is executed, a GUI window open up, and it asks to proceed the installation. To select [Yes], the confirmation
process moves on . Click [Next], and the license agreement shows up. Accept the license agreement by selecting [y]. Then,
click [Next]. The window shifts, and asks the location that the SDK is installed. At the default, the location is descried below.
/home/beat/OMAP35x_Android_Graphics_SDK_3_01_00_03
If this location is fine, click [Next]. Caution, if an existing directory is selected, the new directory,
OMAP35x_Android_Graphics_SDK_3_01_00_03, is not automatically created, and the files are just installed.
The files listed below are installed.
$ cd /home/beat/OMAP35x_Android_Graphics_SDK_3_01_00_03

Rules.make †
To bild SGX, Rules.make is need to be edit. In this process, kernel module, which is built with make install, is
placed in the certain directory. The directory is predetermined by droid rootfs. Please create android footfs before
process is carried on. The locations of SGX and rowboat build directory depend on individual setups.

Revision Check and Build SGX core †
Execute the make command, kernel module is built.
Execute the make install command. At its option, identify the type of a processor and select the module for
the processor.
OMAP3530 ES 1or2 = 2.x
OMAP3530 ES3.0 = 3.x
AM3517 = 3.x
AM37x = 5.x
Since bc10 is a clone of BeagleBoard, please select 3.x. To confirm the settings, follow the direction listed on
this page. Start OpenEmbedded Linux, execute the devmem2 command, and check the revision of SGX core.
Since bc10 is equipped with OMAP 3530, this is how to examine the revision of SGX core.
./devmem2 0x48004B48 w 0x2
./devmem2 0x48004B10 w 0x1
./devmem2 0x48004B00 w 0x2
./devmem2 0x50000014 > sgxrevision.txt
Execute the commands above, it generates the output shown below.
/dev/mem opened.
Memory mapped at address 0x4001f000.
Value at address 0x50000014 (0x4001f014): 0x10201
This output (0x10201) indicates that the module should use here is for OMAp3530 ES3.0, and its version is 3.x.
This is the result of the executing make install command (including the option).
$ make install OMAPES=3.x

Configuring initrc for PowerVR SGX †
To utilize PowerVR SGX on android, the configuration for the service is required. Use initrc.patch, which is located
in ~/OMAP35x_Android_Graphics_3_01_00_03/.
$ cd ~/rowboat-eclair-dsp/out/target/product/beagleboard/android_rootfs
$ patch -p1 -b < ~/OMAP35x_Android_Graphics_SDK_3_01_00_03/initrc.patch
android_rootfs is ready for use. Make android_rootfs archive for placing the bootable SD card.
$ cd ~/rowboat-eclair-dsp/out/target/product/beagleboard
$ sudo ../../../../build/tools/mktarball.sh ../../../host/linux-x86/bin/fs_get_stats android_rootfs . rootfs rootfs.tar.bz2
