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 ...
Hello together, i have an application running with TZEN, unfortunately the readings of the internal temperature sensor calibration values are always zero.Is there a secure address where the values are stored ?Or any chance to get the values out in TZ...
Hello,I'm a developper from the CEA using STM32H573 and I am characterizing the chip boot time in various configurations. With STiRot activated (250 MHz and a 128 Kb image) I found 31 ms which is twice as much as the boot time indicated in the docume...
I am working on B-L4S5I-IOT1A board, and trying to connect the STSAFE A110 chip, with the reference of L476RGTx LQFP64 board's examples provided by stm. and getting below error's 1. pairing .. STSAFE-A1xx initialized successfully Pairing demonstrat...
I am trying to figure out if we can both use secure boot (with Trustzone) and dual bank at the same time. I see in AN0007 that "SWAP_BANK activation by option byte is not supported by STiRoT." Is there some other way to swap banks without using the o...
