Error initializing DMA: not found on DevCloud FPGA instance



I was trying to run the object detection example from OpenVINO with FPGA support on DevCloud. However, the example dose not work as expected. 

The scripts I used for environment setup is as followed. I used fpga_runtime instance in interactive mode. There are many bitstreams in the installation folder with "SSD" or "RMNET" in their names, I just randomly chose one as the DLA_AOCX. Not sure if this is the cause.

qsub -I -l nodes=1:fpga_runtime:ppn=2 -d .
source /glob/development-tools/versions/oneapi/beta06/inteloneapi/ sh
source /glob/deep-learning/versions/openvino_2019R1/openvino_fpga_2019.1.133/bin/
export DLA_AOCX=/glob/deep-learning/versions/openvino_2019R1/openvino_2019.1.133/bitstreams/a10_dcp_bitstreams/2019R1_RC_FP11_SSD300.aocx

When I ran the example, I got the following error. The program complains that that it failed to initialize the DMA, and then hangs forever after logging "Start inference (1 iterations)". The Python example does not work either, the Inference gives out the same error and everything fallback to CPU execution.

$ ./object_detection_sample_ssd -m open_model_zoo/model_downloader/Retail/object_detection/pedestrian/rmnet_ssd/0013/dldt/person-detection-retail-0013.xml -i demo/car.png -d HETERO:FPGA,CPU

Does anyone know hot to solve this issue?

Hi Shaojie,

Since you have posted the same question in another thread, I will proceed to close this thread. 

Further communication/queries are to be posted to Thread 856728.
