Hi,
I just started experimenting with a DSPC-8682 card in Linux (Ubuntu 14.04 LTS, 64 bit). I can successfully run some of the demos included within the MCSDK Video (version 02_02_00_45), but I can only do this once. When I try to run it the second time the demo hangs. Also, for some reason, resetting the DSP's always fails.
I use the following scripts to run the demo:
- After host boot up, I set the environment and run "driver_init" and "./init_dsps.sh 1250" from the Linux Desktop SDK (version 01_00_03_00)
- In the pcie_h265enc_demo/scripts directory of MCSDK Video, I do:
-
- source setDemoEnv.sh
- ./dnld_dsp.sh 8
- ./demoSave2File.sh
These steps are successful. I have verified the output *.265 file with a third party HEVC decoder and everything looks ok.
However, I am not able to run the demo a second time. The encoder either hangs or the output displays messages including "Mailbox messages found in newly opened TX mailbox". When I try to reset the DSP's (using "reset_dsp.sh"), I get "ERROR: Reset code is not working". After trying to reset the DSP's, the host usually freezes, up to the point where I have to do a hard reset.
Any ideas on how to get this resolved?
Best regards,
Jürgen
