Hi everyone

When I enable task scheduling and uninitialize the IIC module, an error occurs,becouse of OSIF_SemaDestroy(). why?

I2C_MasterDeinit() and use flexio for iic

was I2C_MasterInit() called before, which should create osifSema?

Hi petr

I'm glad to receive your reply. I created a task and started task scheduling.

This is my code

I2C_MasterInit(&flexio_instance, &i2c_pal_flexio_MasterConfig0);

/* Initialize Interrupt priority for FlexIO I2C driver as bus master */

INT_SYS_SetPriority( FLEXIO_IRQn, configLIBRARY_MAX_SYSCALL_INTERRUPT_PRIORITY );

.........

I2C_MasterDeinit(&flexio_instance);

After this line of code "(void)OSIF_SemaDestroy(&(master->idleSemaphore));"

and the code jump to "portFORCE_INLINE static void vPortRaiseBASEPRI( void )"

I do not know how to receive this problem........

Best regards

Hi,

maybe this happens due to the lack of heap and stack of the task, so to avoid this try to increment the task's stack and the Total heap size.
