Hello,I'm currently working on a project that involves using the SFBU (Secure Firmware Bootloader Update) due to the limited flash size of the MCU. I've set up an external EEPROM to store the entire firmware before the update process.I've made necess...
Hi, I am looking for some API which supports chain of certificate feature for NetxSecure TLS, Just like mbedtls_ssl_conf_ca_chain() API in MbedTLS.Need help. Thanks in advance.
Hi Community, I'm in a process to combine the SBSFU and Application file into single intel hex using srec_cat.exe doesn't work.srec_cat Application.sfb -binary -offset 0x08010000 -o APP_Offset.hex -intelsrec_cat STM32G0B0RE_SBSFU.hex -intel Applicati...
Hello everyone,I hope this message finds you well. I'm currently working on a project based on the STM32U575ZIT6 microcontroller and have successfully read and written to the flash memory with TrustZone disabled. Now, I am looking to enable TrustZone...
Hello all,I'm working on SBSFU for the STM32F4 controller. A shell script has to be provided in the pre-build option of STMCUBEIDE. But while building the project I get the following error. c:/st/stm32cubeide_1.4.0/stm32cubeide/plugins/com.st.stm32cu...
Hello,I am working with STM32F030RCTx controller. The CubeMx software is not supporting Default Polynomial State: "Disable". I wanted to use a custom CRC polynomial and need help initiating the same. Here is a screenshot for reference:Thanks.
I've been trying to set up the AES peripheral so that it's only using the hardware derived key from the SAES peripheral (without setting any clear text key). However, the only method mentioned in the reference manual on using the DHUK is through the ...
We are using STM32H750VBT6 rev V and have encounter boards with mcus that freezes when we try to use the CRYP. So far we have seen that on failing boards the crypto registers are zeroed immediately after initialization but on a functional board ther...
Hello,I'm trying to use the SAES/AES shared key functionality in a Trustzone (TZEN=1, RDP = 0), using the functions provided by the HAL library. The board I use is the B-U585I-IOT02A.The only project example I found is with Trustzone disabled, but it...
Hi,I'm trying to encrypt and decrypt in my device, running on a STM32H753, using AES ECB.I'm initializing crypto like this: hcryp.Instance = CRYP; hcryp.Init.DataType = CRYP_DATATYPE_8B; hcryp.Init.KeySize = CRYP_KEYSIZE_256B; hcryp.Init...
