Hello,I'm having trouble using the RNG peripheral on the STM32F207.I'm using the HAL functions to set things up and I keep getting back the same number. I've made sure to enable the RNG Clock. See the steps below:Enabled RNG CLK: __RNG_CLK_ENABLE()En...
Hi all, I am using button input from separate input (Separate PCB). After I disconnect that PCB, SBSFU automatically goes into the Updating mode. Even I tried to do an internal pull-up but it also doesn't work. I tried two methods of internal pull-up...
We were running tests originally with the g474re eval board to test/integrate SBSFU functionality. We needed to disable dual-bank mode with the STM32CubeProgrammer before being able to transfer via Ymodem. We are now trying on the g491 and are failin...
Hi ST,I am working with the NUCLEO-WB55 and we are adding some char in service but we don't know where we can find information for these fields * @param Security_Permissions Security permission flags. * Flags: * - 0x00: None * - 0x01: AUTHEN...
Hello,I am developing a SBSFU for a custom application on a NUCLEO-H753ZI board. The application works well on its own. However, when I switch its linker script for the one of the example UserApp delivered with the SBSFU archive, I encounter some une...
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...
