Good morning,
I am working with the STM32MP1 and the STM32H7 and will make use of the SRAM memories for critical data. For my application and its security I need more information about the memories.
Is there any detailed description or analysis...
Hello,
I am trying to manage some interrupts in the M4, specifically the Tamper Interrupt.
Using the STM32CubeIDE (CubeMX) I am unable to select the Tamper interrupt that shows in the NVIC peripheral, when I select it, it gets deselected automati...
Hello,Is there a way to access the Tamper or backup registers or the backup sram from the MCU? Or is it physically imposible to do so?Edit:I am still looking for an answer, I just saw in the RCC registers that I can enable BKPSRAM bits to:enable the ...
Hi, I am looking all through the wiki, but I do not see any clue on using the tampers as a wakeup source.How can I configure the tampers to wake up the stm32mp1 from low power modes?Is it posible to wake up from VBAT? Or is VBAT only a energy mode to...
Good morning,I would like to know if I can disable the JTAG in the STM32MP1. Once my project is finished I do not want this interface to be active. Is there a way to disable the JTAG/SWD interface with registers/fuses/OTP?Kind regards,Andrés
Thank you Sarra and Danish, I am looking for more deep knowledge of the memories rather than at application level.Thanks Patrick, we are trying to add more security to the already provided mechanisms of the processor.We are studying how we can implem...
Hello Olivier,Thank you for the information.I am asking these questions because we might use the processor for our projects and we need to know what can be done and what can not in order to use it in the safest and most secure way possible. Our use c...
Hello @Community member Thanks for the answer, I made a test and can confirm the M4 has access to the tamper, did not test the bkpsram though.The wiki (https://wiki.st.com/stm32mpu/wiki/STM32MP15_peripherals_overview) is misleading in this aspect, a...
