When using X-cube-sbsfu, why is swap area size constrained to be at least equal to the size of the largest flash sector? Is there a way to modify SBSFU to work with a smaller swap area?
On STM32F746, largest sector is 256K and total flash size is 1M. This means that 1/4th of our flash is lost to the swap area. As a result, we do not have enough flash memory left to implement the dual image variant. We are now trying to optimize the ...
How to make X-CUBE-CRYPTOLIB V3.1.0 to perform AES-192 encryption compatible with other online tools?
I am using X-CUBE-CRYPTOLIB V3.1.0 on STM32L0 to perform AES-192 encryption with a 192-bits key and 128-bits IV. Encrypted Data by STM32L0 can be correctly decrypted by STM32L0 using the same library.However, when I copy the encrypted data, key and I...
Resolved! SBSFU: Memory Fault when trying to read external SPI Nor Flash through QSPI in STM32F730
Hi I am now trying to port the SBSFU project to my STM32F730 discovery board.I would like to use the SBSFU in single image mode to upgrade the firmware in the external Nor flash connected via the QSPI interface.My idea was to replace the flash relate...
What is the exact expected sequence for the YMODEM protocol used in IAP and SBSFU?
Hello,for some STM32 controllers ST offers for application-update the IAP and SBSFU modules:https://www.st.com/en/embedded-software/x-cube-iap-usart.htmlhttps://www.st.com/content/st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm32-e...
HI, I'm working with STM32F103R8 on AES .The input key which I enter is not stored properly I tried by simply displaying the key through UART.Here I missed the 13th to 16th elements.This happens only for a 32byte array.
Can anyone help me with this,I have attached the code below.Thanks in Advance
STM32 capabilities
Hi,I would like to move my project to STM32 from another MCU.There are some requirements that I have to comply with and I would like to know if STM32 is a good idea or not.I need to be able to flash the firmware using USB without an USB to UART conve...
Resolved! How to downgrade level 2 read out protection in stm32f7 board?
Hi everyone,I was trying to protect my code by read out protection. But before uploading program, mistaken changed the read out protection to level 2 using of stm32 utility software. Now, I don't able to connect my board to st-link.After search for t...
Extend bytes for application fw version in the image header
For our application, we require more than 2 bytes to identify the fw version. However, the current SBSFU has only 2 bytes fw version in the header. What is the easiest way to add a few more bytes for fw version? Thanks!
