RappId Bootloader Utility

maharajshreekum — Wed, 26 May 2021 14:00:09 GMT

I wanted to know while flashing the bootloader code and app image code to the MPC5748 Dev kit,

What is the purpose of selecting the Start Address when the Rappid tool itself clears all the flash?

How we will make sure that the bootloader code is not erased after flashing the application image, since both "Erash flash Only" & "Erase and Program" option clears the entire flash.

Or I have misunderstood the concept of serial bootloader for MPC 5748G ??

please help!!

Hi,

start address is the address Rappid bootloader jumps to after the application code is downloaded.
Rappid bootloader is located at flash block started at 0x78C000 and this block is locked by bootloader code, so will not be erased.

Thanks for the reply Petr,

So, if wanted to erase only a particular section of flash starting from some random flash address, is this possible with RappiD.?

Because in the Rappid Release notes, it is written that both the options "Eras Flash Only" and "Erase & Program" will completely erase the flash area.
