|
|
* @details This function uses the provided address to swap the stack pointer and then load
|
|
* the address of the reset handler to be executed. It checks the current system mode
|
|
* (thread/handler). If in thread mode, it resets into the other application.
|
|
* If in handler mode, isr_abort is executed to ensure that handler mode is left correctly.
|
|
* It then jumps into the reset handler of the other application.
|
|
*
|
|
* @note This function will never return, but issues a reset into the provided application.
|
|
*
|
|
* @param[in] start_addr Start address of the other application. This address must point to the
|

initial stack pointer of the application.
