Part Number:PROCESSOR-SDK-OMAPL138

Tool/software: TI-RTOS

I have tried to execute IPC example ex02_messageq on LCDK and failed.

Installation:

processor-sdk-linux-omapl138 v05_00_00_15

processor-sdk-rtos-omapl138 v05_00_00_15

Installed both SDKs and followed the instructions in IPC Quick Start Guide -

The build is finished correctly. I have also built again the linux kernel after building bios-ipc and installed everything in my NFS filesystem

When I am executing /usr/bin/MessageQApp I get the expected results

I then stop and reload the DSP with ex02_messageq dsp image

echo 'stop' > /sys/class/remoteproc/remoteproc0/state 

    remoteproc remoteproc0: stopped remote processor dsp

cd /lib/firmware

 rm rproc-dsp-fw
 ln -s /home/root/server_dsp.xe674 rproc-dsp-fw

echo 'start' > /sys/class/remoteproc/remoteproc0/state

    remoteproc remoteproc0: powering up dsp
    remoteproc remoteproc0: Booting fw image rproc-dsp-fw, size 4138868
    virtio_rpmsg_bus virtio0: rpmsg host is online
    remoteproc remoteproc0: registered virtio0 (type 7)
    remoteproc remoteproc0: remote processor dsp is now up

I then execute:

root@omapl138-lcdk:~# ./app_host DSP
--> main:
--> Main_main:
--> App_create:
^CIpc: Caught SIGINT, calling Ipc_stop...
root@omapl138-lcdk:~#

The example does not execute correctly.

Any ideas?

Thanks
