AM572x IPC 3.43.02.04 on QNX SDP 7.0 Beta

Chris Pendleton

Hello. QNX gave me access to their SDP 7.0 Beta package to run on the AM572x EVM / X15. The SDP 7.0 is the first QNX version with a BSP for this board.

I was (and still am) hopeful that I could be able to use the TI IPC toiols for QNX with SDP 7.0. I am using the latest Processor SDK release (03.01.00.06) with IPC 3_43_02_04. I followed the instructions at http://processors.wiki.ti.com/index.php/IPC_Install_Guide_QNX. The builds went smoothly, and I was able to transfer the TI binaries to the target.

The problem comes when I try to use the resource manager to load firmware into one of the slave processors.

# ipc DSP1 /bin/dsp1/NameServerApp.xe66
Starting IPC resource manager...
Memory fault

Looking at the QNX system log, I see:

It looks like the DSP binary is not being loaded correctly. Any ideas?

Thanks,

Chris

Hi,

QNX is not supported by TI. Please contact the BSP provider for support.

I am asking about about the TI-IPC software, which contains a QNX build. Also, TI documentation such as http://processors.wiki.ti.com/index.php/IPC_Install_Guide_QNX and http://processors.wiki.ti.com/index.php/IPC_3.x#QNX give instructions for the QNX IPC build and installation. Are you saying that this was not developed by TI?

Thanks,

Chris

Hi Biser.

I am looking at TI source code included in Processor-SDK-RTOS / IPC. For example, /ipc_3_43_02_04/qnx/src/utils/TiIpcFxns.c (below). I think this source code belongs to TI as seen in the file header. It it designed to interact with QNX. Are you saying that you do not support this software that is included with Processor-SDK?

I have notified the RTOS team. They will respond here.

Thanks Biser, but after a long debug session it appears as if the TI-RTOS firmware files for the slave processors are being corrupted when the filesystem is created. The IPC looks like it is working when I manually transfer the files. I will need to figure the issue, but it is not your problem. Thanks.

Hello user4867806. I cannot give it to you as I had to go through an approval process and receive a special license, but you can contact QNX directly with the request. So far it works very well on the AM572x EVM.
