STM32F7 CRC unit: is behavior of bit reversal settings on 16- and 8-bit data sizes intentional?
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...
Resolved! Key Generation and Secure Key Storage on STM32WL55
We are working on developing a host-module that requires two-way device authenticationThe controller we are planning to use is the STM32WL55 Series.We have the following Queries.1) Does STM32WL55 has a functionality to locally generate a certificate ...
Error in STM32H753 reference manual related to AES-GCM ?
I've found an inconsistency between different reference manuals of STM32 embedding the CRYP peripheral, about the management of IVs in GCM mode:The HAL seems to implement the second solution.Could you confirm ?Best regards
Why were references to the STM32L051C8 RNG peripheral removed?
In some ST documents the STM32L0X1 is listed as having an RNG peripheral and older versions of the CMSIS headers list the RNG register addresses. Moreover, enabling the peripheral and using it appears to generate random numbers. However newer manual...
STM32H753ZI CRYP module, AES-CTR, counter register, documentation vs observations
Hello,So I'm using a Nucleo-H753ZI (so STM32H753ZI) and I am trying to implement manually (aka without using the HAL library you provide) some drivers of the CRYP module. More precisely, I need to use the CRYP module with AES in counter mode (AES-CTR...
Resolved! Where's the CRC and the size of the whole firmware application stored whenever a new application is flashed on to the System flash?
Does the controller perform a CRC confirmation check before running the application to check if the firmware is corrupted? If so, where does this happen; in the bootloader or the application itself? What does it do if the CRC turns out to be wrong? S...
Accessing "Backup SRAM" with RDB Level 1 from Code in RAM
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...
Resolved! Inconsistency between STM32H7 AES HAL and Reference Manual
HelloI'm starting to implement AES-GCM on STM32H753 (rev V).I've found an inconsistency between the HAL and the Ref Manual.The STMicro HAL for AES for STM32H7x3 is setting some bits called NPBLB in CRYP_CR register if the product revision is above re...
