I have installed ti-processor-sdk-linux-k2e-evm and ti-processor-sdk-rtos-k2e-evm and rebuilt the IPC library successfully. Then I build the ex02_messageq example and get two files named app_host and server_core0.xe66. I download these files into the k2e evm below "/lib/firmware" folder. But when I run the app_host and get the info. as follows.
root@k2e-evm:~# ./app_host -l
--> main:
Processor List
Error: main_host.c, line 201: Ipc_start failed
<-- main:
root@k2e-evm:~# ./app_host DSP
--> main:
^CIpc: Caught SIGINT, calling Ipc_stop...
root@k2e-evm:~# ./app_host -h
--> main:
Usage:
app_host [options] procName
Arguments:
procName : the name of the remote processor
Options:
h : print this help message
l : list the available remote names
Examples:
app_host DSP
app_host -l
app_host -h
I failed to start IPC and it seemed the program can't find the other core. My app_host.c list as follows.

I think there must be some steps between download the server_core0.xe66 and app_host and run the app_host. Can you tell me what's it?
