Hi,

Looks you are using MCSDK package, which is already obsolete. You may consider migrating to Processor SDK RTOS for C6678. Please see https://e2e.ti.com/support/legacy_forums/embedded/tirtos/f/355/t/353777 if it helps, maybe IPC package is missing.

你好：

感谢你的回答，这句是我在例程“ vlfft_evmc6678l”中复制到我自己的工程里，用来实现多核通信。例程运行的时候没有出现这个错误。并且我在自己的工程里已经添加了ipc的路径，但上面错误部分给出的路径没有ipc的路径。

Hi,

IPC is a RTSC package, you need to register it with CCS. In CCS------>Window----->Preferences--------->Code Composer Studio--------->Product

你好：

我设置了这个之后错误变成一个：

说明资源路径位置类型

不能沿着以下路径找到包“ ti.sdo.utils”：'C：/ ti / bios_6_33_04_39 / packages; C：/ ti / mcsdk_2_00_09_21 / demos; C：/ ti / pdk_C6678_1_0_0_21 / packages; C：/ ti / ndk_2_21_02_43 / packages; C：/ Users / zjm / workspace_v5_5 / C6678_Test_DSP_Net_v20190320 / platform; C：/ ti / ccsv5 / ccs_base; C：/ ti / dsplib_c66x_3_1_0_0 / packages; C：/ ti / xdctools_3。确保包路径设置正确。.xdchelp / C6678_Test_DSP_Net_v20190320行266 C / C ++问题

包路径依然没有ipc，但我这边路径设置了的：

Hi,

As you registered IPC 1.24 and 3.23 under CCS, I thought you should have a way to select one of them to use. Then they should appear in the search path when you compile the code. Below is screenshot a typical SYSBIOS project, not the same as yours, but you can see the RTSC package needs to be selected.

When I built it, I have them in the search path:

"C:\\ti\\ccs930\\ccs\\utils\\bin\\gmake" -k -j 8 all -O

你好：

感谢你的回复。我在RTSC是添加了的，从图中可以看出：

依然是之前那种错误。

Hi,

In your .cfg file, you have some IPC setting like this:

/****** IPC - Shared Memory Settings ********/
/* IPC packages */
var Ipc = xdc.useModule('ti.sdo.ipc.Ipc');
var Settings = xdc.module('ti.sdo.ipc.family.Settings');
var ListMP = xdc.useModule('ti.sdo.ipc.ListMP');
var GateMP = xdc.useModule('ti.sdo.ipc.GateMP');
var SharedRegion = xdc.useModule('ti.sdo.ipc.SharedRegion');
var HeapMemMP = xdc.useModule('ti.sdo.ipc.heaps.HeapMemMP');
var MultiProc = xdc.useModule('ti.sdo.utils.MultiProc');

I am not sure why the CCS project didn't search the registered IPC package. Maybe something messed up? Do you have a clean IPC example project proven working as a starting point?

Regards, Eric

你好：

我没有用IPC示例项目做，这个IPC是我想实现主从结构的多核通信而加进去的。而且我之前的东西太多没有办法移到IPC示例项目运行。
