Hello! I would have an app that is divided between a secure part and a non secure part. The memory definition is as following in the secure linker script: /* Memories definition */ MEMORY { RAM (xrw) : ORIGIN = 0x30000000, LENGTH = 320K FLASH (rx) : ...
We attempted to change the product state to "Closed" on STM32H523, and this operation was successful. We can perform a full regression to the "Open" state. However, we are experiencing unexpected behaviour during the provisioning stage. The code in t...
Greetings,I want to implement encryption in STM32F205RG. I came to know that there is no Hardware support, so is there any STM32 crypto library for STM32F205RG ? I want to implement AES encryption and decryption function. Thanks for support.
Hello ST Community,I am working with an STM32U5 based board and facing serious issue related to RDP Level 2 and debug access. I am attempting to recover the device using STM32 Programmer CLI and Cube Programmer but it is not responding as expected e...
I am still very new to embedded programming. I am trying to walk through the SBSFU example application for the B-U585I-IOT02A from STM32CubeU5. The board I am using is STM32U5A9J-DK. I tailored some of the build settings in STM32CubeIDE for STM32U5A9...
For context , i was trying to testout OMEiRoT and DA ,i successfully managed to lock , and regress using the password method and i tried to replicate the STiRot method shown in the STiRot handson video to try the OMEiRoT example project in the nucle...
Hi,I'm using an STM32H563VG (1MB Flash version) on a custom board. I have a STLINK-V3MINIE connected and I'm using STM32CubeProgrammer.When I'm doing a full chip erase, the content of the flash memory is not altered, everything is still there when I ...
I am testing this with a set of STM32F573 boards, the example taken straight from CubeMX example selector for the STM32H573I-DK board without any changes. I am running it until after the call to HAL_CRYPEx_WrapKey() and before the call to HAL_CRYPEx_...
Good day!I have custom board with cpu stm32l562. I am prepared all data and global license. CPU prepared by script file from package STM32CubeExpansion_SFI_v1.5.0 L5.This operation is OK.But after if start programm by Cube Programmer ( v 2.19 ) - i h...
STM32H730, an invalid tag is generated for payloads that are not a multiple of 4, as described in Re: STM32U545 AES GCM Tag mismatch - STMicroelectronics Community.AES-CCM: no issues, everything works.AES-GCM:The HAL already handles required padding ...
