Hello,I am trying to generate output with adjustable pulse width using One Pulse mode.The output pin is in a Pull-Up state, with an initial state of High. When One Pulse mode is activated, it outputs a Low signal for the specified duration.However, t...

Hello,I am developing on the STM32MP131FAE board in a bare-metal environment.This chip does not have internal Flash, so I am planning to load a bin file from external Flash at initial boot.The Flash will store two bootloaders and two main firmware im...

Hello,I am currently working with an STM32MP131 in a bare-metal environment and utilizing external DDR3. For this, I am using the HAL library, and in most cases, it works as expected. However, I occasionally encounter an issue where the HAL_DDR_Init ...

I have tried changing the internal PUPD settings, but there is no change.I checked the DR register inside HAL_XSPI_Transmit , and although the value is always 0, the data output is performed correctly. Even when sending 0x00, the pin only stays in a ...

When power is initially applied, IO3 remains in a Low state and is not pulled up on the PCB.In the CubeMX settings, it is configured as No PUPD (no pull-up/pull-down).After transmitting data, it becomes fixed in a High state.Additionally, there is so...

Does this mean that if QSPI SNOR booting is hardware-compatible, a separate driver needs to be created to use it in a bare-metal environment?Could you provide the information required to create the driver? According to the readme.txt file, the sou...

What does it mean that it does not support QSPI flash memory?If so, what is the "Serial NOR Flash on QSPI" mentioned in the Boot Mode section of the STM32MP131 Datasheet?
