New ContributorHost Pipes OpenCL
Hi,
I am working with an Stratix 10 GX development kit, and I have a problem with the example design loopback_Host Pipe. When the host communicate with the OpenCL command clSetKernelArg(kernel, 0, sizeof(cl_mem), (void *)&write_pipe), the following assert is shown:
host: acl_hal_mmd.c:2486: acl_hal_mmd_hostchannel_create: Assertion `device_info[physical_device_id].mmd_dispatch->aocl_mmd_hostchannel_create' failed.
This problem just happens with host pipes.
How can I solve this?
Thanks in advance.

Did you get the example in https://www.altera.com/support/support-resources/design-examples/design-software/opencl/gzip-compression.html https://www.altera.com/support/support-resources/design-examples/design-software/opencl/host-pipe.html May I know which version of compiler that you were using? Host channel is not supported on the later versions of the compiler, but it is available on 17.0 and 17.1.
MDavi14The source code that I used is the example in:
https://www.altera.com/support/support-resources/design-examples/design-software/opencl/host-pipe.html,
The aocl version is:
aocl 18.1.0.222 (Intel(R) FPGA SDK for OpenCL(TM), Version 18.1.0 Build 222 Pro Edition
That means, the 18.1 do not have support for the host-pipe example such as the software and hardware requirements suggest?.

Yes, I would suggest you use the example design base on the software requirement.
- KennyT_alteraIs there any update?
