Getting "HAL Kern Error: Read/Write failed from addr x, read y expected z" when running multithread OpenCL application on CycloneV SoC

To ensure, that I didn't just write an incorrect program, I used the standard multithread example: https://www.intel.com/content/www/us/en/programmable/support/support-resources/design-examples/desig...

Hi,

​thank you for your response.

The output of lsmod seems to always be:

root@socfpga:~# lsmod                                                          
Module                  Size  Used by
aclsoc_drv              8916  0 
root@socfpga:~#

While reproducing the error, I observed one additional erroneous behavior:

​

Sometimes, the application just doesn't finish and instead hangs. I've attached the output of several program executions. If the program didn't finish, I aborted it with control-C, the application did still react to that. In the attached log these cases can be identified by the "^C" at the end of the program output.
