XN File

[rp181]

I have the follow XN file:

Code: Select all

When I try and run the program (just calls a function on core 0 with some printfs), I get:

Code: Select all

xrun: Program received signal ET_ILLEGAL_RESOURCE, Resource not valid.
      0x000101d0 in wakeCore ()

Does anyone know what/if the problem is the XN file?

Shouldn't be...

Code: Select all

 <Declarations>
      <Declaration>core stdcore[1]</Declaration>
   </Declarations>

1 instead of 2 ?

[rp181]

There are 2 cores, in nodes Master and Slave. When declaring an array, stdcore[2] has a length of 2, so 2 cores.

There are 2 cores, in nodes Master and Slave. When declaring an array, stdcore[2] has a length of 2, so 2 cores.

This does seem right, as documented in the 11.2 Tools user guide, section 8, which outlines a 2-core example like yours,

listing

Code: Select all

< Declarations >
< Declaration > core stdcore [2] </ Declaration >
</ Declarations >

and the comment

The board contains two XCores. The declaration “core
stdcore[2];” is exported to the header file <platform.h>.

Max.
