Hi all,One small doubt on the tamper configuration, is it possible to configure both active and Passive tamper in the Same project/API, or both should be in different project/API. why this doubt is as Seed is not required for Passive tamper, so does...
Hi,Where can I find a documentation for the version 4 of X-CUBE-CRYPTOLIB ?Regards,Fred.
Hello As in the title, for my project I'd like to know exactly what is the maximum storage capability/size of the device NV memory.The TPM used is ST33TPHF2XI2C.I wasn't able to find anything in ST documentation (datasheet, application notes).Waiting...
Hello for allIn last days i was begin to implementation AES to work on stm32f423I am using example in NIST Special Publication 800-38A to take key-128 bit, input data that plain text , encryption and decryption data.but nothing seems to work , when ...
Hello,There is No-Stretch GetCheckSum command in I2C bootloader command, Does someone know what the CRC algorithm used in the bootloader?Many thanks.B.R.Frank
hello, I'm run a STM32H573DK in OEMiROT example.but following errors occured.[INF] TAMPER Activated[INF] BANK 1 secure flash [0, 15] : OB [0, 14][ERR] Unexpected value for secure flash protection so, I find why occurred this error. In the ob_flash_p...
Hello support team,Have a Nice day.I am working on STM32U585ZIT6 Controller and investigating SBSFU for firmware upgrading.I list our specifications for a custom bootloader below.Enable TrustZoneEnable Dual bankRun time firmware write in the second b...
Hi, with MCU STM32U585QII6QTR we encrypted an AES key using SAES engine and stored it in Internal Flash in RDP Level 0 and then moved to RDP Level 1. When we decrypt the key that was encrypted in RDP Level 0 using SAES engine, we didn't get our origi...
Hi TeamGreetingsI have some general queries with respect to the usage of the TFM Application provided in firmware package.(Some of them were asked previously but to get a clear understanding)1. For calling a secure module(example UART or ADC) - can i...
If LL_CRC_INDATA_REVERSE_WORD is set and 8-bit data is provided via LL_CRC_FeedData8(), the resulting CRC is not what is expected. It appears the combination of word-reversal and byte-submission mangles the submitted data in some way, when I had expe...
