Hi All,

I am asking a follow up question to my

https://community.st.com/0D50X00009XkYInSAN

. Now that I am able to write in a certain flash location, I would like for it to not be overwritten every time I program the board. Is it possible and if so, can anyone point me in the right direction for the necessary changes?

I am currently on a STM32L432KC working within Atollic TrueSTUDIO 7.0.1.

Thanks!

you can protect your memory area using Proprietary Code Read-Out Protection (PCROP): protection against read and write operations on Flash and SRAM memories.

For more details about PCROB, I rocommend you to have a look to

Hi Nesrine,

Thank you for your quick response. I think this will work! I will test it out in the next few days.
