hello world launch hang - intel a10 FPGA

Hi, Can I know what version of OS are you using ? Looking at aocl diagnose, it seems you are using multiple devices. 1. Can you try aocl diagnose acl0 or acl1 and check if you see and READ/ WRITE transactions. 2. I notice you are missing the aocl flash command, please follow steps as mentioned in https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/opencl-sdk/aocl_getting_started.pdf Page 36, Programming the Flash Memory of an FPGA Let me know if this is helpful to you. Thanks, Arslan
