As described.I am using the B-U585I-IOT02A Discovery development kit. Just testing basic SPI operation and trying to use all three SPI lines.Using basic setup with STM Cube ID I can send data using HAL_SPITransmit over SPI1 and SPI2. Trying to do the...

I am trying to us the LPTIM low power timer to trigger interrupts intermittently while the MCU is in STOP2 mode, but I am unable to do so. I am testing the interrupts by toggling a GPIO pin and checking the output on a scope.Without STOP mode I see t...

I am using the B-U585I-IOT02A discovery kit with the STM32U585AI chip.Using code generated by STM Cube.Attempting to configure use of the SMPS power supply results in a timeout in the HAL_PWREx_ConfigSupply() function.In the sequence below, smps_mod...

I am using the B-U585I-IOT02A discovery kit with the STM32U585AI chip. Attempting to set the system clock value in STM Cube to anything that would result in voltage scaling above PWR_REGULATOR_VOLTAGE_SCALE4 results in a timeout and thus failure in t...

I am writing C++ projects using STMCubeIDE and running into a problem when using classes or other C++ features.Even when choosing that the project be a C++ project, I can't build the code. Manually changing the file extensions to .cpp makes the code ...

I solved the issue.SPI clock pin was PG9, which is in the VDDIO2 power domain. I enabled VDDIO2 power with the HAL_PWREx_EnableVddIO2() function and this solved the problem.It was not really related to SPI. Even trying to use PG9 as a regular GPIO wi...

Managed to solve this thanks to https://community.st.com/s/question/0D53W00001zhW8ISAU/port-application-from-stm32l4-to-stm32u5-waking-from-stop2-by-lpuart-rtc-etc.Needed to set the LPTIM1AMEN bit in the RCC_SRDAMR register to enable autonomous mode ...

Thanks for sharing, this helped me port from stm32L5 to stm32u5. Was having a really hard time getting a low power timer to wake up the MCU from STOP2 modeThis is my questions: https://community.st.com/s/question/0D53W00002GYwT0SAL/lptim-interrupt-ca...

I tried the same code with a similar configuration on a different development kit, the STM32L562E-DK Discovery. It works as expected there. Still not working on the STM32u585

Yes. I have tried deploying through debug mode and then disconnecting the debugger and restarting the MCU.Also tried compiling in Release configuration and flashing the MCU manually.Neither works
