6467T的engine_open失败的原因？

你在开发板上，用“ CE_DEBUG=2 ./app.out ” 运行app,把输出的信息贴一下吧。

CEapp-> ERROR: zzzzzzzzcan't open engine lvengine
在这句附近，上面还提示can't start 'lvserver.x64P'; Processor_create failed
，帮忙分析下，多谢。。。。

“@0,829,379us: [+7 T:0x40946b60] OP - Processor_create_d> Loading and starting DSP server 'lvserver.x64P' FAILED, status=[0x80008008] (look for error code 'DSP_EBASE + 0x8' in dsplink*/packages/dsplink/gpp/inc/errbase.h)”
       很多时候可以查看这个errbase.h找到错误原因，不过，我查了下，你这个是“A general failure occurred ”，那可能的原因就很多了。
       我手头没有板子可以试，无法重现你的现象，有几个猜测，你可以参考一下：
1，lvserver.x64P是否拷到了目标板上？
2，运行" lsmod | grep dsplink " 命令，看dsplink.ko是否成功加载？
3，仔细检查app端的cfg文件，或者你可以贴出来一下，看有没有配错。
4， 检查server端的tcf文件，特别是内存分配，内存上堆与栈的分配，可能会导致加载不了x64p.
5,    你之前是否有重编过dvsdk或者dsplink?
6,    提醒一下，我注意到你用的是dvsdk_1_40_02_33，这是一个比较老版本的dvsdk,使用dm6467T 的话，最好到以下链接，下载最新版本，因为，老版本的dvsdk下，时钟的配置，编码器和codec engine的版本，都会让你的芯片发挥不了最佳性能。
software-dl.ti.com/.../index_FDS.html
7，上面说的几种可能，根据调试信息，有些是可以排除的，不过，你最好还是都仔细检查下。

另外你推荐我用哪个版本的sdk 对6467T更适合？

1, ceapp.cfg文件中，你仔细检查一下这个部分：

var myEngine = Engine.createFromServer(
   "lvengine",        // Engine name (as referred to in the C app)
   "lvserver.x64P", // path to server exe, relative to its package dir
   "ti.sdo.ce.lvproject.server" // server package
   );
注意：
第三个参数，是server包的准确名字。你找到你的server目录，里面有一个package.xdc文件，要确保此处第三个参数与package.xdc中定义的包名字一致。
第二个参数是x64p文件在server目录中的准确路径。这是比较容易搞错的地方。
 
2,    你的SDRAM是256M的吗？ 你运行下cat /proc/cmdline，看看你内核的启动参数中，"mem=size"  给linux分了多少内存？再检查loadmodules.sh中为cmem分配了哪些内存，把linux, cmem占用的内存，与tcf中为dsp分配的内存对照一下，看有没有冲突的地方吧。
3，tcf中你做了哪些修改，我说的新版本的dvsdk链接已经发给你了。
http://software-dl.ti.com/dsps/dsps_public_sw/sdo_***/targetcontent/dvsdk/DVSDK_3_10/latest/index_FDS.html

是DVSDK_3_10_00 3_10_00_19

我把新版DVSDK缺省的tcf和tci文件发你，你对比下你的配置。
 
 
 

总DDR SDRAM 是 128MB ,
Linux 分配了108M,
内核参数如下：
mem=108M console=ttyS0,115200n8 noinitrd rw ip=192.168.0.230:255.255.255.0:192.168.0.223 root=/dev/nfs nfsroot=192.168.0.223:/opt/nfs
网络测试的参数
x64p 就在server目录下面，名字是匹配的
//////////
loadmodules如下：
#!/bin/sh
# insert cmemk, tell it to occupy physical 120MB-128MB, create
# 20 4K buffers, 10 128K buffers  and two 1MB buffers
insmod cmemk.ko phys_start=0x87800000 phys_end=0x88000000 pools=20x4096,10x13107
2,2x1048576
# insert dsplinkk
insmod dsplinkk.ko
# make /dev/dsplink
rm -f /dev/dsplink
mknod /dev/dsplink c `awk "\$2=="dsplink" [print \$1]" /proc/devices` 0
/////////
我检查了下没有冲突的地方，在开发包内我用同一个 .x64P 放在6467T板子上执行，包内自带的video_copy.out调用它 可以执行成功，但是这个video_copy的源码没有；然后我重新编译了包内的另外一处有源码的video_copy例子生成.out 还是用上面的.x64P,也是出现engine_open 失败的情况，看来是应用程序配置的问题，但是不太好检查，我正准备下载最新DSK看看参考里面的配置和你给的tcf.tar文件能不能执行成功。。。。

你确定你用的是128M的DDR吗？
如果，那样的话，你的linux用了0-108M, cmem用了120-128M， 那你tcf里为dsp配的内存全都在128M之后，根本没有内存去放了。
你这种内存分配，是按256M来分配的，如果你实际的内存只有128M的话，问题就在这儿了。

我记得1.4版本的dvsdk默认提供了几个不同的server及tcf, 你说的，有的.out可以调用成功，有的不可以，我怀疑是因为它们使用了不同的tcf.
你查看下，可以成功执行的那个包内自带的video_copy.out相对应的cfg文件，找到它的server下的tcf文件。 与你发我的tcf文件做个对比。应该就能定位到问题 了。

非常感谢我再试一下，不过之前我好像试过这种解决方案，好像是没有奏效我再试一下，谢谢！还是看中文亲切啊，一直在看英文论坛，头都大了呵呵

都是新手，不用客气，你说的很对，有时候错误提示一样未必是同一个原因引起的，你在看看编译应用程序时用的DSPLINK 模块的的配置是否和应用程序的一致，在CFG_Davinci_DM6467.c里面，

我目前碰到的问题可以说和楼主一样，我使用的是DM6467   codec engine中的video_copy，自己编译出来的app.out,就是无法正常运行，使用提供的那个app.out可以跑我自己编译的server。不知道如何解决？？ 求见解

你好，我的问题解决方法，在帖子里已经回复，请找找
