Dear all,
I use the hal_stm32x0_led(char c) debug,and found
it have trouble in stm32_misc.c 's hal_variant_init() , hal_stm32x0_led(3) run
OK,hal_stm32x0_led(7) failed
void hal_variant_init( void )
{
#if 1 //!defined(CYG_HAL_STARTUP_RAM)
hal_start_clocks();
#endif
// Attach EXTI springboard to interrupt vectors
HAL_INTERRUPT_ATTACH( CYGNUM_HAL_INTERRUPT_EXTI9_5, hal_exti_isr, 0, 0 );
HAL_INTERRUPT_ATTACH( CYGNUM_HAL_INTERRUPT_EXTI15_10, hal_exti_isr, 0, 0 );
#ifdef CYGSEM_HAL_VIRTUAL_VECTOR_SUPPORT
hal_stm32x0_led(3);
hal_if_init();
hal_stm32x0_led(7);
#endif
}
I think it is caused by the difference between STM32F407IGH6 and STM32F407VGT6
, does anyone have an idea?
