XK-1A link two boards together

[cicga]

hi all,

I have two XK-1A boards i plug them and wrote code template:


#include <xs1.h>
#include <platform.h>

on stdcore[0]: out port outLL = XS1_PORT_8A;
on stdcore[0]: out port outRL = XS1_PORT_8B;

on stdcore[1]: out port outRH = XS1_PORT_8A;
on stdcore[1]: out port outLH = XS1_PORT_8B;

void R_L(){

}
void L_L(){

}

void R_H(){

}
void L_H(){

}

int main(void)
{

par{
on stdcore[0] : R_L();
on stdcore[0] : L_L();
on stdcore[1] : R_H();
on stdcore[1] : L_H();
}


}

its compile fine but when I am trying to write it on hardware I have message:
"xrun: Number of cores in binary does not match the device"

like the is no second board connected...but it is.

Take a look at the dual XC-1A's project, it should give you an idea of how to work with links between the boards, I know it's a different development board but the guide on there is quite detailed and should be easy to adapt.

What output does "xrun -l" give?
The XK-1 2-board example should work without problems.

,
output gives:

"xrun: Number of cores in binary does not match the device"

sorry link to XK-1 2-board example does not work.where did you find it?

[Bianco]

http://www.xmos.com/xk-1a

Under application software.

I asked you to give the output of "xrun -l" which cannot give some error about your binary.
"xrun -l" lists all devices in the JTAG chain, that sounds like a good starting point for debugging your problem.

What XN file or target did you use to compile it?

[cicga]

Bianco,
i'v tried that code it give the same message:
xrun: Number of cores in binary does not match the device
:roll:

[Bianco]

So what does "xrun -l" output? Does it show both cores?
Please answer all my questions otherwise we cannot help you.

[cicga]

sorry Bianco

yes xrun -l show both devices
and in run/debug config tab show L1[ 0..1] device too

now I have new message:

Description Resource Path Location Type
first index of array `stdcore' exceeds its upper bound xk1-concurrent.xc /cc/src line 13 C/XC Problem

now I am using sample code:
#include <platform.h>

#define PERIOD 20000000

on stdcore [0]: out port led0 = XS1_PORT_8B;
on stdcore [1]: out port led1 = XS1_PORT_8B;

void flashLED (out port led, int period);

int main (void) {
par {
on stdcore [0]: flashLED (led0 , PERIOD);
on stdcore [1]: flashLED (led1 , PERIOD);
}
return 0;
}

[Bianco]

Try this binary.
You should see the LEDs flashing running from one board to the other and back.
You should also see Hello World0! Hello World1! in your command window.
(It is the example from the XMOS site, i confirmed on hardware that this works).
Execute it with "xrun --io dual_xk1.xe"

Bianco,

pls take a look on multicore.jpg picture may be this will help...

i cannot run your file - command prompt telling:
"xrun: Invalid option -io"
