Hello!

I'm using Picocomputing m506 board

I have a problem with execution Altera OpenCL helloworld example.

I have this output when i'm truing to run host app:

Some info:

I'm using CentOs 6.5

I have successfuly installed quartus + altera opencl sdk 13.1

aocl diagnostic successfuly passed

A couple of questions:

1) Did you recompile the kernel file for that board? The hello world design example doesn't come with a pre-compiled hello world image so you might be attempting to use a pre-compiled .aocx file for a different board.

2) Assuming you did# 1 did you remember to target the Pico board? This is how you would compile the OpenCL image file: aoc hello_world.cl --board <board> I'm not sure what the name of the pico board is to pass in as <board> but you can find the name by running aoc --list-boards.

Problem solved.

It was bug with CvP, Picocomputing make update to BSP and flash.pl script. After this, hello_world example has run successfull.

Thank you!
