As per Firmware encryption need, we need to have OTFDEC module and External Flash, where we can store Encrypted firmware on External Flash and on every reset of MCU, we decrypt on the fly with help of OTFDEC module and load it on RAM. From there it c...
Need support to have STM32F769 Hardware 32BIT CRC generation and same value should be generated by STM CUBE IDE POST COMPILATION 32BIT CRC for BINARY file .So a quick background is once the project is compiled and binary is generated we use SREC_CAT ...
Hi all,I am not sure if I understood the reference manual right: When I activate Read Out Protection RDP Level 1, I can no longer access RTC Backup registers if I execute in RAM. I did not read that also Backup RAM is inaccessible. But it looks it i...
Hi ,I am working on STM32U575 nucleo board .Flash got locked (code freeze) and i have to power cycle board to run my application in below cases :Switching from RDP0 to RDP2 in firmware on Pushbutton operation . Application freeze . It runs again when...
I'm struggling to get the SPI CRCERR flag and IRQ to work the way I expect.I am using an STM32WB55. The SPI communication in full duplex is working. The master is adding the CRC to the end of the Tx data. On the slave side, the CRC is read in. I can ...
Hello !STM32L4R9I support True Random Number ( 32 bits per 1 time generation)I run an example and then make an program to generate 100.000.000 bits1 st iteration (100M bit) : HW is 0.5 and Passed NIST Test2 nd iteration (100M bit) : HW is 0.5001 and ...
I see that those keys are hardcoded in the code. As I understand they are responsible to LTK and CSRK.Should I change ERK and IRK between devices , so they are not the same? Asking for security reasons.
Hi,I'm computing CRC32 with 04C11DB7 polynomial with different methods : through python binascii.crc32(...), on the following website " https://simplycalc.com/crc32-text.php ", and with ST embedded module on STM32G483.On basic strings such as "012345...
Hi i am using STM32L071CZ controller and i am trying to firmware update the controller using UART protocol and during that firmware update in boot mode what all security features i can implement for a secured firmware update ,Security features which ...
