From AN5185 I understand that up to 100 keys can be send to FUS for storage, but any index will only be written once. So once I have reached 100 writes, e.g. because I have constant pairing keys between devices but I allow to disengage and reengage s...
Hello,I'm struggling to find any information regarding possibility to remove the keys stored through FUS CKS.My understanding is, if the keys are constantly being stored to some reserved space in flash memory, this reserved space will eventually be f...
I have a strange issue here. I'm trying to do a short, blocking, UART transmission.I have a 23 byte uint8_t array ( MSG ) that I construct before calling the HAL_UART_Transmit() function to send the data. (SLAVE_MSG_SIZE = 23, UART is a pointer to th...

Hello,I try to build the STM32CubeExpansion_SBSFU_V2.6.2 for STM32H750B-DK. I use STM32CubeIDE Version: 1.9.0 on Windows 10.The build result is suspicious: More details: The first section is overflown by 3479%. What I did wrong? How to fix it? Th...
Am testing the x-cube-sbsfu on H7A3 (using H7B3 project with OTFDEC disabled). After enabling SFU_MPU_PROTECT_ENABLE, I always ran into mem manage fault when the function HAL_RCC_GetPCLK1Freq is called during HAL_UART_Init: An MPU or Execute Never (...
Hello communityGreetingsi have a requirement to write and read data from the SRAM2 and Backup RAM from the TFM Application example. please suggest how can i write and read an array of bytes(10 byte) from the SRAM2 and Backup RAM in the above mentione...
Hello,I would like to setup a secure area on the h755 board. My setup is as follows:I have a secure app that runs permanently on the m7, and on the m4, there is a non-secure app running.I want to configure all but the last sector of the m7 as secure....
