cannot get printf to work over jtag Topic is solved

[ycui7]

I am having so many problems as a newcomer to the XMOS ecosystem. Here is one.

The printf function does not work over jtag. But somehow it can work over xscope.

Here is the code I have

Code: Select all

#define DEBUG_UNIT ETHERNET_MODULE
#include "debug_print.h"

void AudioHwInit()
{
xk_evk_xu316_AudioHwInit(config);
printf(“rnAudioHwRemoteDone2_printf”);    <== this line is executed with --xscope option, but not --io
debug_printf(“rnAudioHwInitDone”);		<== this line never show up on the sceeen with --xscope option
}

nothing ever show up with --io option on xrun.

some suggestions would be nice.

one thing I cannot figure out is how to set the compile to build as debug not release. where to change between debug/release?

Hey, you will need to disable xscope in your application. This will either be by removing the `-fxscope` flag from your xcc invocation. Or if you have a "config.xscope" file then set the "enabled" attribute to false in there
