Function Documentation

◆ mpc55xx_start_prologue()

void mpc55xx_start_prologue ( void  )

Start prologue.

In case the BSP enabled the MPC55XX_ENABLE_START_PROLOGUE option, then this function will be called directly after the Boot Assist Module (BAM) jumped to the start entry defined by the reset configuration.

This function executes in the context initialized by the BAM. There exists no valid stack pointer and the internal RAM has an invalid ECC state.

The default implementation does nothing. The application may provide its own implementation.
