Macro Definition Documentation

◆ exception_Handler

#define exception_Handler ( e )

Value:

    __ASM ( "tst lr, #4 \r\n"                   \
            "ite EQ \r\n"                       \
            "mrseq r0, MSP \r\n"                \
            "mrsne r0, PSP \r\n"                \
            "b " #e "_Handler_callback \r\n");

Exception handler asm caller.

Note: The exception_Handler should be called with corresponding exception name e as parameter

Function Documentation

◆ Error_Handler_callback()

void Error_Handler_callback ( const uint32_t stack[] )

prints informations about current Hard Fault exception

Parameters

[in] stack - pointer to stack address

Note: HardFault_Handler_callback should not be called directly use exception_Handler() which prepares pointer to current stack instead

Warning: Depending how arm is fucked up, informations may not be printed, at least, you could inspect exception and stack through debug breakpoint

Note: Never returns (anyways, arm fubared!)

◆ Get_Reset_Source()

eResetSource Get_Reset_Source ( void )

Get the last source of reset.

Warning: This function should be called soon after reset (before or after SystemClock_Config())

Note: This function using some special macros can't be inlined, thus can't be in sarmfsw stm32 header unfortunately

Returns: Last Reset Source

◆ HardFault_Handler_callback()

void HardFault_Handler_callback ( const uint32_t stack[] )
