Hi,the HW PEC generation of the I2C Interface has two limitations that i have not been able to work around until now. The PEC calculation is reset after a stop, but can not be initialized after start. If you want to program a SMBus Slave that is capa...
Hello, in one my project I need to have SBSFU. On first version on my board I had STM32F405 uC and was successfully ported example STM32F413H_Discovery_2_Images_SBSFU. For test the porting I changed startup file in the discovery example for 405 s...
Hi AllI need to fill the security policy about STM32 crypto library(STM32CubeExpansion_Crypto_V3.1.0), and had three function name to fill.1, Entropy Health test2, Repetition Count Test3, Adaptative Proportion TestAnyone knows these?Regards,
Hi there,I am trying to understand the state of the option byte values in flash after a forced mass erase (changing RDP from level 1 to 0) for a STM32L151 (Cat.2).From my own investigation it appears that after a forced mass erase all the option byte...
I'm sure I'm missing out something obvious as I'm fairly green with limited programming experience, but I could not port the STM32F413 project to run on my own STM32F417 board. I've scoured this topic and followed Security Part6 - STM32 security ecos...
I have a routine that I have used for years on other processors and on PCs to get a CRC16 X-25 from a string. I'd like to get the hardware CRC to use the same CRC16.I have tried every variant in the STM32CubeIDE and have not been able to get same out...
I am working on the SMT32L4 series controller and want to perform some cryptographic operation on data.
Hello, I have hundred of boards where I need to update our custom bootloader which resides in blocks 0/1/2/3/4 (the bootloader "partition" is 5KB). The new bootloader code resides inside the firmware binary, when the firmware boots, it checks if the ...
HelloFile "STM32_Cryptographic/Inc/Common/macros.h" defines macros MIN and MAX without any "#ifndef" around. Thus compiler warnings "redefined" are generated, if the file is included by customer code after headers of BLE stack.File STM32WPAN/ble/ble_...
Hi Community. I'm trying to port the LoRaWAN_End_Node_DualCore with SBSFU application example to CubeIDE but I'm facing a lot of linker errors. Is there a way to have a working CubeIDE project for this example? I'm working with the dual core STM32WL5...
