I’m face a problem while trying to startup LM3S811 on qemu.
I have build and run Demo:CORTEX_LM3S811_GCC on qemu, what modification I’ve made is just removing all existing tasks and then creating one task which will print message periodically. But after vTaskStartScheduler run, there is no any message printed out.
xTaskCreate( vAliveTask, “Alive”, configMINIMAL_STACK_SIZE, NULL, configMAX_PRIORITIES - 1, NULL );
218 static void vAliveTask( void *pvParameters )
221 OSRAMStringDraw(“Start”, 0, 0);
223 while (1)
226 OSRAMStringDraw(“ALIVE …”, 0, 0);
227 vTaskDelay( 2000 / portTICK_RATE_MS );
$ qemu-system-arm -machine lm3s811evb -kernel gcc/RTOSDemo.axf
I have debugged this issue by gdb and found that xPortPendSVHandler has never been called, this means no context switch occurred. So my question is: did I miss any configurations or are there any mistakes I’ve made?
