Beagleboard xM with TI DVSDK 4_01_00_09

Beagleboard xM 跟之前的 Beagleboard有相當多的差異,除了CPU / DSP 時脈的提昇,週邊也多了Ethernet, USB Hub 及 Camera interface.
不過 Nand flash 據說是因為成本的因素而拿掉了.因此Beagleboard xM只能經由 SD card boot.

TI DVSDK 提供很完整的多媒體展示,包含Media encode / decode, OpenGL 3D demo.
接下來將試著將Beagleboard xM DVSDK 安裝至 SD card.

1.參考DVSDK FAQ
http://processors.wiki.ti.com/index.php/DVSDK_4.x_FAQ#How_to_build_and_install_DVSDK_4.01_on_BeagleBoard-xM

根據DVSDK FAQ得知所需要的必要環境是 Ubuntu 10.04. Cross compile 為 CodeSourcery ARM 2009q1

2.Download DM3730 DVSDK 4.01 from TI
http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_4_00/latest/index_FDS.html
下載 dvsdk_dm3730-evm_4_01_00_09_setuplinux,大小約為1.5G.
下載時 TI 會要求帳號密碼,請自行註冊登入.注意帳號的Email 不能是yahoo之類的免費帳號.

下載完成後先變更檔案權限為可執行
$ chmod 755 dvsdk_dm3730-evm_4_01_00_09_setuplinux

執行安裝
$ ./dvsdk_dm3730-evm_4_01_00_09_setuplinux

3.Download patch script for DVSDK 4.01 to support BeagleBoard XM

http://processors.wiki.ti.com/images/5/5b/Setup-dvsdk-4-01-beaglexm-110126.zip

TI DVSDK並沒有支援Beagleboard xM,因此必須要做一些patch.
解開zip檔後會得到檔案 setup-dvsdk-4-01-beaglexm-110126.sh.
將它放在DVSDK root目錄,再依照以下內容修改 setup-dvsdk-4-01-beaglexm-110126.sh.

這個修改是為了可直接連上internet及修正 git am 所造成的 bug

4.變更權限並執行
$ chmod 755 setup-dvsdk-4-01-beaglexm-110126.sh
$ ./setup-dvsdk-4-01-beaglexm-110126.sh
這時這個script會自動去抓許多patch檔,並更新至DVSDK

5.編譯DVSDK
至DVSDK root目錄下

make clean
make all

6.安裝DVSDK 至 SD card

將SD card 連接至PC, 再來弄清楚device node為何 (用dmesg)
以我來說是 /dev/sdd

$ sudo bin/mksdboot.sh --device /dev/sdd --sdk ${PWD}

*         WARNING! Make sure your computer does not go     *
*                  in to idle mode while this script is    *
*                  running. The script will complete,      *
*                  but your SD card may be corrupted.      *
*                                                          *

到這裡SD card已經準備好了

7.以SD card boot Beagleboard xM

boot成功最後會看到以下登入畫面,請以root登入,無須密碼.
