Booting_DSP_Binaries

http://processors.wiki.ti.com/index.php/Boot_Images_for_OMAP-L137#Booting_DSP_Binaries 这个网页里面的running部分提到：Generate AIS image：

• Open a command window and navigate to the directory of HexAIS_OMAP-L137.exe
• Run the following command: HexAIS_OMAP-L137.exe -o OMAPL137-ARM-LED.bin DSP\Debug\OMAPL137-ARM-LED-DSP.out ARM\Debug\OMAPL137-ARM-LED-ARM.out

这里的command window 是指什么？AISgen tool中并没有发现这个。

Shine：

是指windows的DOS命令窗口

到windows start->Run, 输入cmd.

http://processors.wiki.ti.com/index.php/Boot_Images_for_OMAP-L137#Booting_DSP_Binaries，这里面给的CCS工程和源代码为什么和http://processors.wiki.ti.com/index.php/Boot_Images_for_OMAP-L137#Booting_ARM_Binaries中的源代码是一样的，都是包含DSP UBL 和 the ARM LED blinking program，http://processors.wiki.ti.com/index.php/Boot_Images_for_OMAP-L137#Booting_DSP_Binaries只是讲启动DSP核的程序，不是不用写UBL代码吗？还有，在这个网页中为什么没有用到AISgen Tool,反而和启动ARM核代码时一样，用的是HexAIS tool？为什么？

http://processors.wiki.ti.com/index.php/Boot_Images_for_OMAP-L137#Booting_DSP_Binaries这里的例程有问题. 如果只boot DSP代码, 步骤如下.

Booting to a DSP application on OMAP-L137 is pretty straightforward:
Use AISgen to generate an AIS file (.bin or .ais) from your original .out file
Flash your AIS file to the very beginning of SPI flash (i.e. offset 0)
Make sure your boot switches are set for SPI flash boot
Disconnect the emulator and power cycle the EVM

You don't need a UBL or U-boot if you want to boot to a DSP application.
