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

void HardFault_Handler_callback
