Hello,
I am unable to execute Desktop Linux SDK filetest demo on Advantech Octal board DSPC8682. I followed the steps in the wiki page http://processors.wiki.ti.com/index.php/Desktop-linux-sdk_01.00.00_Getting_Started_Guide. I also patched the PDK and built the DSP side file test demo application for DSPC8682. When I use the scripts to download the DSP executable, the script says "download image success". So I guess the executable might have been loaded properly but when I run the host application, it gets stuck waiting for response from DSP. The exact place it gets stuck on the host is waiting to open receive mailbox which involves reading DSP memory and checking the owner word.
I do not know whether DSP has been properly booted up also since I have no idea how to debug DSP side in this set up. Hence I would also like to know how to debug the DSP side when booting via PCIe.
On a side note, I looked at Lightning_PCIE tarball which came with Octal board. But I am unable to load the dsp loader module. It fails in "request_mem_region" API for "ti667x_L2SRAM" which is on BAR1. Hence I am also unable to proceed in running the sample demos which came with this. My best bet was to use the Desktop Linux SDK's download manager to load DSP executable since I was able to run demos on 6678 EVM booting via PCIe on the same system where I now have installed octal board.
Earlier, I was able to run this demo successfully on a 6678 EVM. Any help would be greatly appreciated.
Thanks,
Hari
