hello guys,
I am working with MQX 4.2 . in IAR and i created a project with 3 tasks and was working fine. Then i changed the bsp for my LCD code and then i found my code with 3 task is showing some linker error in IAR.
Error[Li005]: no definition for "main" [referenced from cmain.o(rt7M_tl.a)]
The code doesn't have a function as main.
These are the tasks.
{DAC_TASK, DAC_Task, 1500, 8, "Dac_Task", MQX_AUTO_START_TASK, 0, 0 },
{ADC_TASK, ADC_Task, 2500, 9, "ADC_Task", 0, 0, 0 },
{ KEYPAD_TASK, Keypad_Task, 5000, 8, "Keypad_Task", 0, 0, 0 },
then i tried with the same bsp and psp in kds and found that it is giving same kind of error in PSP of that code
C:\Freescale\Freescale_MQX_4_2\mqx\build\kds\psp_frdmk64f\debug/..\..\..\..\source\psp\cortex_m\compiler\gcc_arm/comp.c:201: undefined reference to `main'
error is shown at this function
void toolchain_startup(void)
{
// initialize necessary hardware (clocks, ddr, ...)
init_hardware();
// initialize data - copy and zero sections
// static variables can be used on return
data_startup();
// register destructor calls of static objects
atexit(__libc_fini_array);
// run constructor calls of static objects
__libc_init_array();
// run main, if return go to exit
exit(main()); // here is the error undefined reference to main.
}
does anybody have any idea about what is this error and how to solve it
please help
thanks and regards,
Olivia
