I have an issue with stack corruption on the first FPU access (specifically vmov instruction) after jumping to the application code from SBSFU. I noticed that when the application starts the LSPACT bit is set in FPCCR register. Clearing the bit in st...
I'm currently testing the UART bootloader on a NUCLEO-L496ZG-P, the bootloader itself works fine and i've written a python script which can upload .bin files to the controller.The problemi'm having is that the product will need Readout Protection in ...
I'm attempting to configure peripherals in STM32CubeMX, but I'm getting error_handler calls from my DMA configuration for ADC1.All the necessary peripherals (DMA1 channel1, ADC1) are configured as secure in CubeMX, but when HAL_ADC_MspInit attempts t...
I am working on STM32L552 Nucle0-144 board with Trustzone enabled. Secure code starts from 0x0C000000 and non secure code vector table located at 0x08040000. After completing the initializations in secure code I am calling non secure reset handler by...
I think using other secure element should feasible, but not sure how difficult it is.As ST provides a set of tools like SBSFU etc middleware, may I know is that easy to change to support other secure element other than STFAFE-A110?
Hi allMy cipher text from STM32F429 crypto library(AES-CBC-256) is CTS(Ciphertext Stealing)，but the cipher text can'e decrypt by openssl on my PC because the file length is not correct.What can I do to solve it?Thanx
I am trying to learn wireless firmware development.For that I am looking for a microcontroller with only Physical layer(ie when I place an ASCII character 'a' in an address it takes its binary value and transmit it as RF Signals).All other layer shou...
hi here I am configure the CRC register of STM32f469IITx I am using the function CRC_CalcCRC(); to generate the crc for 32-bit data.i am not getting the crc please any one help me.uint32_t data=0xAAAAAAAA;uint32_t crcvalue=0x00000000;how i am using ...
Hi,May I know the "STM32CubeExpansion_Crypto_V4.0.1" has implemented hardware accelerator via stm32l5xx?Please advise,Rgds,QiZhang
Hello,The mentioned board utilizes usb otg communication through the USB connector. DM and DP pins are PA11 and PA12 which are directly connected from the mcu to the USB connector (no available GPIO pins). There is no usart or uart connected to the D...
