Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
As per SBSFU memory mapping details, to download application remotely, we need to define ACT_SLOT, DNLD_SLOT and SWAP_AREA range.What is the typical size of swap_area ??For STM32H753, as we have 2MB Flash only and One Sector 1 127 KB, is reserved for...
Hi,In TFM and SBSFU applications, by default the anti-tamper protection is enabled for both internal tamper events and external tamper events. It is activated at the start of TFM_SBSFU_Boot, and remains active. In case of tamper detection, sensitive ...
What are the STM32 MCUs, support KMS middleware feature ??is STM32H753VI supported this KMS feature ??If NO, is there any way STM32H7 can generate Pair of Keys on the fly during run time to create Self Device Certificate ??
@JHOUD @TDK @Dimitrios Bako I have configured HDP as follows :By Bootloader .icf details are :define symbol __ICFEDIT_region_ROM_start__ = 0x0C000800;define symbol __ICFEDIT_region_ROM_end__ = 0x0C007FFF; Configurations when i debug t...
Follow up of my previous messages on AES-GCM on STM32H753.I think that the ref manual is wrong: I implemented my code this way and the busy bit never clears.The HAL code is not polling on this bit neither.i've checked on other STM32 ref manuals it is...
Hi,I am using the the SecureBoot on a STM32L4 with the KMS, I have some questions related to the protections:As I use the KMS, I read in the UM2262: "With KMS middleware integration, SBSFU keys are no more stored in a section under PCROP protection b...
Hi I want to ask that In SBSFU example for STM32G474 in user app application Firmware update is done using ymodem protocol i.e. UART can we used SPI protocol instead of this is this possible to use SPI or there is any limitation????? Please suggest
Do we have provision to configure STM32H753 as Secure Mode or not using SECURITY Pin in Boot selection ??or is this completely owned by STM ??is Devices received with enabling SECURE MODE it self ?? as mentioned in below Diagram ?? is STM does this S...
Hi,One of the requirement for the FLASH layout on dual bank product (like the STM32L4 that I use) is that the FWALL code section overlaps the the FWALL NVdata (see the attached image). If I understand correctly the reason is that if the banks are swa...
