1、最近在使用 TI 的 TMS320DM6437 处理器，安装完 CCS3.3 后，又安装了 DVSDK.可是发现 PSPdriver 下的 example 无法编译通过，经过几天的研究，终于发现了一些环境配置上的细节，整理出来供大家分享。1.安装 CCS3.3，推荐安装默认路径“C:CCSt io_v3.3”,安装时按照提示进行，对于“TI Emulator driver“ 选项可以取消不安装，在有些 XP 系统上，如果不取消此项的安装，会在安装结束后会死机，原因不明。2.完成 CCS3.3 的安装后，再安装 DVSDK,推荐安装默路径“C:dvsdk_1_11_00_00“,安装过程为会提示
2、安装最新的 DSP/BIOS，可以选择不装，如果安装了，会在 CCS3.3 目录中多一个子目录 bios_5_3x_xx（可能与 CCS3.3 自带的 DSP/BIOS 版本不同 ,x 为版本号，根据具体情况有所不同）3.以上两个软件安装完成后，要设置系统环境变量，供编译工具链使用。具体参数设置如下（如果是在默认路径上安装的话）BIOS_INSTALL_DIR C:CCSt io_v3.3bios_5_31_08BIOSDVSDK_INSTALL_DIR C:dvsdk_1_11_00_00BIOSUTILS_INSTALL_DIR C:dvsdk_1_11_00_00biosutils_1_

4、INSTALL_DIR C:dvsdk_1_11_00_00xdc_2_95_024.设置完成后，CCS3.3/bios_1_xx_xx 下的例子都有可以编译和运行了。但是 C:dvsdk_1_11_00_00pspdrivers_1_10_00 下的例子还不能编译通过。以目录 C:dvsdk_1_11_00_00pspdrivers_1_10_00packagestisdopspdriverssystemdm6437biosevmDM6437 rt 下的例子说明如何配置，使 example 能正常编译。5.用 CCS3.3 找开工程文件 dm6437_evm_ rt_st_sample.pj
5、t，这时如果打开 dm6437_evm_ rt_st_sample.tcf 文件会出错，选择 dm6437_evm_ rt_st_sample.tcf，右键选择 DSP/BIOS config-text edit,打开文本模式，找到“utils.importFile(“ti/sdo/pspdrivers/system/dm6437/bios/evmDM6437/ rt/dm6437_ rt0.tci“);“替换为utils.importFile(“dm6437_ rt0.tci“);保存。这样这个脚本文件就能正常运行了。但是这时编译会提示找不到一些文件。这是因为 XDC 工具读取的路径文件中的
6、路径没有设置设置方法如下：打开 C:dvsdk_1_11_00_00pspdrivers_1_10_00packagestisdopspdriverscommonpsp_xdcpaths_common.dat内容如下-/ DO NOT MOVE OR DELETE THIS LINE JavaScript xdcpaths/ Note: Use /FORWARD/ slashes for all directories!/Section for non-DVSDK users/Section 1 Starts/ Root directory for the PSP Drivers instal

8、ry/ It is the directory where PSP is installed.pspInstallDir =“pspdrivers_“ + pspversion ;/ EDMA3 installation directory/ It is the directory where EDMA3 LLD is installed.edma3InstallDir = “C:/dvsdk_1_11_00_00/edma3_lld_1_05_00“;xdcpaths =/ EDMA3 build directoryedma3InstallDir + “/packages;“ +/ PSP
