OMAP4之DSP核（Tesla）软件开发学习（三）使能DSP核

目标：

1、编译或直接获取DSP映像tesla-dsp.bin。

2、boot并使能DSP核（这个可以看启动打印或者进入/d/remoteproc/omap-rproc.0/参看dsp调试信息）。

 

过程：

1、直接获取blaze_tablet 4AJ.2.1版本中事先编译好的tesla-dsp.bin，将此文件拷贝到"4AJ.2.1/mydroid/out/target/product/blaze_tablet/system/vendor/firmware/"下，同时更新Linux kernel（驱动支持DSP核），然后重新制作安卓emmc文件系统，并将更新部分刷到blaze_tablet中。

2、使能DSP核：

2.1 启动blaze_tablet，出现如下打印则表明DSP核已经使能。
