Getting a lot of "HAL Kern Error: Read failed from addr x, read y expected z" errors – what to do?

Hi,

thanks for reopening the question.

>From your question, I saw you are using the design example "multithread vector" example, am I right?

Yes, I can reproduce the error using "multithread vector" example.

>May I know other example like hello_world and vector_add can be compile successfully?

Yes, the hello_world example runs successfully, and this bigger project also runs successfully if I only enable one thread.

I'm currently at home, but I can test the vector_add example tomorrow.

>Are you building the BSP in other version and porting the BSP to 18.1 version?

I'm currently using Intel FPGA SDK for OpenCL standard edition Version 19.1.

I'm reproducing the error using the BSP that is offered by the Development board vendor:

Download page: https://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&CategoryNo=167&No=1081&PartNo=4#Files

Direct link: http://download.terasic.com/downloads/cd-rom/de10-standard/DE10-Standard_OpenCL_18.0_BSP.tar.gz

That BSP is meant for version 18.0. Is this a problem?

>Could you try to looking into the version for MMD?

How do I check this?

If I remember correctly, executing `aocl version` on the board shows version 18.0, but I'll check again tomorrow.

Thanks for your help!
