Read out protection level 1

WebWhen RDP protection is set to Level 1, debug tools still can be connected and access all the volatile resources of the MCU (RAM and registers). These tools are used to check the part and/or system, by loading some test code to the RAM. Also, Level 1 protection allows to recover a programmed part by erasing the entire Flash content. Web2. Level 1 ensures the memory read out protection while keeping debug access enabled. From Level 1, the device can move to Level 0 or Level 2. Regression to Level 0 will cause a Flash memory Mass Erase. 3. Level 2 ensures the read-out memory protection the same as Level 1, but also completely disables JTAG/SWD debug access. 10

WebDec 7, 2024 · The Read Out Protection is really the key thing for protecting your code from being accessed by an end user. It basically locks down access to the code from the boot loader, RAM boots and system boots. This means it is not possible to use the boot loader to read the FLASH, or feed a malicious program into the CPU that can scan the flash array. WebThe only way to get it to boot from main flash is to apply power on reset. Accroding to RM0351 section 3.5.1 the readout protection is activated by system reset or power-on reset if debug was active. In my case I have no debugger connected and still the system reset is not enough to activate RDP and boot from main flash. church nativity online https://daisyscentscandles.com
