Generating Option Byte .s19 file

YS.1 · ‎2023-05-04

Hi,

I need to generate option byte file(.s19) which is enabled Read out Protection for STM32F4.

The reason is to program this .s19 file using non ST programmer in production environment.

May i which ST Tool should i used to generate option byte file(.s19) ?

Welcome, @YS.1, to the community!

There is probably no point in trying to put the Option Bytes in an S19, the reason for this has already been discussed here.

Instead, you should consult your programmer's documentation and find out how to use it to set the Option Bytes on the Command Line.

Hope that helps?

Regards
