Hello,The mentioned board utilizes usb otg communication through the USB connector. DM and DP pins are PA11 and PA12 which are directly connected from the mcu to the USB connector (no available GPIO pins). There is no usart or uart connected to the D...
I have set readout protection，the f103c8 chip have automatically set the first four page write protect,now I wanna erase the first four page,how can I unlock write protection first,thank you
Is there any way to use the X-CUBE-SMBUS middleware from ST with STM32F407?The controller does support it but ST's middleware does not.Does anyone know why it would not be supported?The reason I say its not is because the HAL for it is not in the #if...
Hello,I'm having trouble using the RNG peripheral on the STM32F207.I'm using the HAL functions to set things up and I keep getting back the same number. I've made sure to enable the RNG Clock. See the steps below:Enabled RNG CLK: __RNG_CLK_ENABLE()En...
Hi all, I am using button input from separate input (Separate PCB). After I disconnect that PCB, SBSFU automatically goes into the Updating mode. Even I tried to do an internal pull-up but it also doesn't work. I tried two methods of internal pull-up...
We were running tests originally with the g474re eval board to test/integrate SBSFU functionality. We needed to disable dual-bank mode with the STM32CubeProgrammer before being able to transfer via Ymodem. We are now trying on the g491 and are failin...
Hi ST,I am working with the NUCLEO-WB55 and we are adding some char in service but we don't know where we can find information for these fields * @param Security_Permissions Security permission flags. * Flags: * - 0x00: None * - 0x01: AUTHEN...
Hello,I am developing a SBSFU for a custom application on a NUCLEO-H753ZI board. The application works well on its own. However, when I switch its linker script for the one of the example UserApp delivered with the SBSFU archive, I encounter some une...
I am working with STM32H750VBT6 rev. V. I divided the internal flash into protected and unprotected areas. I set option bytes for the protected area. It worked fine. After that I needed to deactivate PCROP protection. I could not do it. I use STM32Cu...
I download X-CUBE-AWS 1.4.0 to compile and install on my STM32F769IDISCOVERY board, everything running ok, but when I configure it to update new app version from OTA, after reboot is shows:= [SBOOT] SECURE ENGINE INITIALIZATION SUCCESSFUL= [SBOOT] ST...
