Currently I'm developing a project with FreeRTOS on a STM32L476VGT. Until now I've been debugging with Ozone(SEGGER) and J-Link (Edu and Ultra+)
Now I would like to "debug" or record system event using SystemView (SEGGER), but it's not working.
first of all some of the configurations I think there are important: 16Mhz HSE --> internal 80Mhz SysClk FreeRTOS V8.2.3
J-link (SCLK,SDIO & SWO connected)
Project created with cubeMx so ST HAl libraries are in use(I know that for many people is bloatware but is what it was when I get the project).
main.c
#include "SEGGER_SYSVIEW.h"
//// -- includes, prototypes and definitions
void main (void){
/// -- Hardware init
SEGGER_SYSVIEW_Init(1000, 80000000, 0, 0);
SEGGER_SYSVIEW_Start();
/// - tasks creation
osThreadDef(defaultTask, StartDefaultTask, osPriorityNormal, 0, 128);
defaultTaskHandle = osThreadCreate(osThread(defaultTask), NULL);
/* Start scheduler */
osKernelStart();
}
I put only the basic lines of code that I have add to the project in order to use the SystemView.
under this lines I attache a screen capture of System Viewer.
EDIT 1:
I've created a new projet to tart from the beginning.
STM32L476RG yes R is another board with 3 leds cubemx : STM32L4 lib 1.10.0 FreeRTOS V9.0.0
main.c
int main(void)
{
HAL_Init();
SystemClock_Config();
MX_GPIO_Init();
SEGGER_SYSVIEW_Init(1000, 80000000, 0, 0);
SEGGER_SYSVIEW_Start();
osThreadDef(defaultTask, StartDefaultTask, osPriorityNormal, 0, 128);
defaultTaskHandle = osThreadCreate(osThread(defaultTask), NULL);
osThreadDef(ledControlTask, ledcontrol, osPriorityNormal, 0, 128);
ledControlTaskHandle = osThreadCreate(osThread(ledControlTask), NULL);
osKernelStart();
while (1)
{
}
}
void ledcontrol(void const * argument)
{
for(;;)
{
HAL_GPIO_TogglePin(LED1_GPIO_Port,LED1_Pin);
osDelay(500);
}
}
Same result:
if I click STOP I get:
Also if I put as it's explain in SEGGER SystemView UM0802 pdf Manual:
SEGGER_SYSVIEW_Init(1000, 80000000, 0, 0);
SEGGER_SYSVIEW_Start();
for:
SEGGER_SYSVIEW_Conf();
I get same output
Many thanks,
Guillermo
