I am working with STM32H750VBT6 rev. V. I divided the internal flash into protected and unprotected areas. I set option bytes for the protected area. It worked fine. After that I needed to deactivate PCROP protection. I could not do it. I use STM32Cu...
I download X-CUBE-AWS 1.4.0 to compile and install on my STM32F769IDISCOVERY board, everything running ok, but when I configure it to update new app version from OTA, after reboot is shows:= [SBOOT] SECURE ENGINE INITIALIZATION SUCCESSFUL= [SBOOT] ST...
Hello,The reference manual for the STM32F207 states that the F20x and F21x family has a cryptographic processor: Ref Manual - Page 508. The datasheet for the F207 doesn't state any support for that though. Is this a mistake in the reference manual?Th...
Hi, actually I 'm planning to write some C code for cryptographic functions for e-signature, encrypt data or decrypt data in IOT devices.There are lots of products here. So I don't know which one is efficient for encrypt or decrypt operations or sign...
Hello.I'm trying to program the main flash memory of STM32F103RCT6 using J-Link while RDP is enabled.I followed main flash memory programming procedure in PM0075 manual.the procedure is in below picture.When only RDP is enabled, I unlocked Flash_CR_L...
I've been able to compile previous versions of SBSFU (P-NUCLEO-WB55.Nucleo/Applications/1_Image) without issues, but with this one I've run into two issues:First, SE code did not fit in SE_ROM_region. I was able to fix this by adjusting the linker ma...

I programmed stm32F103RCT6 firmware using STM32CubeIDE.When Read Out Protection (RDP) is disabled, the firmware works well.But RDP is enabled, the firmware doesn't work.My firmware is transmitting data by UART.when RDP is disabled, Firmware sends dat...
I'm starting two new projects which initially would make use of STM32F1 and STM32F4 MCUs but after reading some articles detailing how easy would be to disable RDP1 and even downgrade RDP2 to RDP1 I become very concerned. Please, anyone with more exp...
Hi there,I currently use STM32L073 for evaluation and found some issue with CRC module.L073 has a CRC peripheral whose polynomial is programmable. And when I programm the peripheral as below, the checksum returns from the module doesn't match the one...
