I loaded my custom built yocto image into my SD card using the STM32CubeProgrammer and the process was completed successfully.However, when I toggled the boot switches to boot from SD card, I was not able to connect my host computer (a Ubuntu 20.04 d...
HiWe are using stm32mp157a processor in my custom board.We want to configure DAC in cortex M4.In stm32h745xi DAC has Default Timer for interrupt.Where as in stm32mp157a we dont have that timer configuration for DAC .you can see the difference in bel...
Hi,I've finally reached the stage where I can test the SSP flowI burned a debug AES128GCM key on my ST-HSM-v2 cardI created a 148 bytes secrets file and passed it through TrustedPackageCreator tool to get the 244 bytes fileI created a signed ssp-tf-a...
Could you explain to me what is the purpose of the different bits associated to the tampers?I am mainly focus on using the passive tampers of the STM32MP1 and I have seen the following configuration bits I don't fully understand:What I understand:Reg...
HI,I'm not able to get the FDCAN filter working on a STM32MP157C-DT2. I'm able to receive valid ID' with no problem, however, invalid ID's are getting through.Would someone be kind enough to take a quick look at my setup to make sure I did not miss ...
I was working on the STM32MP157A-DK1 board which has Cortex-A7 + Cortex-M4 processors. I wanted to configure the watchpoints present specifically on the Cortex-A7 processor via C code. The Cortex-A7 technical reference manual indicates the use of MRC...
