Hello, 

I'm using STM 32 ST-Link Utility to program my MCU. I want to make sure that when I program the board multiple times I don't erase the data saved in a particular page on memory? Can I do that? If so, then please explain how to do it? 

Thank you.

Hi

tejeshwarchandra

,

  • What are you using as STM32 product?
  • 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

Hello Nesrine, 

Thank you for your reply. I just decided to use ST Visual Programmer instead of STM32 ST-Link Utility. It provides much easier to complete my task.
