ucos和freertos_freertos论坛_freertos 8(2)

在task文件里寻找例如以下行，

PRIVILEGED_DATA static volatile TickType_t xTickCount = ( TickType_t ) 0U;

在以下增加这一行

PRIVILEGED_DATA static unsigned portBASE_TYPE uxTopUsedPriority = tskIDLE_PRIORITY;

在函数xTaskGenericCreate中的例如以下代码

uxTaskNumber;

#if ( configUSE_TRACE_FACILITY == 1 )

{

/* Add a counter into the TCB for tracing only. */

pxNewTCB->uxTCBNumber = uxTaskNumber;

}

#endif /* configUSE_TRACE_FACILITY */

的前面增加

#if ( configUSE_TRACE_FACILITY == 1 )

if( pxNewTCB->uxPriority > uxTopUsedPriority )

{

uxTopUsedPriority = pxNewTCB->uxPriority;

}

#endif /* configUSE_TRACE_FACILITY */

openocd FreeRTOS 调试

开启gdb server

openocd -f board/stm32ldiscovery.cfg

调试下载代码

arm-none-eabi-gdb stm32l1xx_freertos.elf

load

这时候server端显演示样例如以下信息
