Hi there,

I am using AURIX Dev. Studio and was testing printf() to print out variable to FSS window. At first it work fine, but after a while (~1min) the program will halt suddenly and a window will pop out saying "No source available for "TC23x.frame[0]"". The disassembly point to a function called _dbg_trap() but I can't find it anywhere in source code.

I have even tried replacing iLLD with V1.0.1.13.0 but still no use.

I have attached some screenshots here. I have also uploaded my project for examination. The project is just the demo project Blinky_LED_1_KIT_TC234_TFT with 2 line added in Blinky_LED.c to keep printing out variable myTest when LED is toggled. You can download it here: https://1drv.ms/u/s!ArYO_KxP91FxgZdETkoIB3ZM9abwGg?e=0iM0tR

Thanks for reading, any reply is appreciated.

I gave it a try over here. Problem confirmed. There seems to be a general issue in the AURIX Development Studio related to printf output which is redirected to the File System Simulation (FSS) window of the debugger. This does not work for a longer time. The use case can be reduced to the following example code:

#include "Ifx_Types.h"
#include "IfxCpu.h"
#include "IfxScuWdt.h"
#include

IfxCpu_syncEvent g_cpuSyncEvent = 0;

int core0_main(void)
{
IfxCpu_enableInterrupts();

/* !!WATCHDOG0 AND SAFETY WATCHDOG ARE DISABLED HERE!!
* Enable the watchdogs and service them periodically if it is required
*/
IfxScuWdt_disableCpuWatchdog(IfxScuWdt_getCpuWatchdogPassword());
IfxScuWdt_disableSafetyWatchdog(IfxScuWdt_getSafetyWatchdogPassword());

/* Wait for CPU sync event */
IfxCpu_emitEvent(&g_cpuSyncEvent);
IfxCpu_waitEvent(&g_cpuSyncEvent, 1);

while(1)
{
printf("Hello\n");
for(unsigned int loop=0; loop<0x10000; loop++)
__nop();
}
return (1);
}

The printf output will fail after some time. This is an erroneous behavior which needs to be sorted out by the ADS support staff.

ADS version I used for testing: 1.4.2

I imported the project into the TASKING TriCore tools v6.3r1 and therein the printf outpt works normal.

Best regards,
Ulrich

Hello, is there an update on this? I'm facing the same issue with 1.9.4, code execution hits a trap after exactly one printf.
