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 ...
In the past I've used F401 and the following code works flawlesslyHAL_FLASH_Unlock(); HAL_ICACHE_Disable(); uint64_t myWord = 0x00000001; HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD, 0x080C0000, myWord); HAL_GPIO_WritePin(LD2_GPIO_Port, LD2_Pin, G...
Hello everyone, I'm learning about MCUboot. Currently I have tried searching for information online but still don't have an overview. So I hope everyone shares their experiences about MCUboot (things to learn here) and give me some programs to better...
Hello, I have been modifying the OEMUROT_Boot application and associated build scripts in ROT provisioning to complement our custom firmware project. (See my previous post on this topic for details). This is for the STM32N6, using the DK discovery ki...
I know this matter is dense and niche, so ill try to articulate my process in a digestible manner and add some memes.I Recently downloaded sbsfu-v2-7-0 (legacy) package.After some YMODEM bug fixes, i have a working example SBSFU for only one ACTIVE ...
