I'm trying the LPBAM_LPUART_TransmitReceive with a NUCLEO-U575ZI-Q but I can't make it works.I enabled the debug by removing the init of PA13 and PA14. The MCU got stuck into an hardfault when calling ADV_LPBAM_UART_Transmit_SetFullQ() for the secon...

I have an overconsumption of ~50uA when going into stop2 mode with the DMAT of LPUART set.Because of the silicon bug (LPUART does not generate DMA requests after setting/clearing DMAT bit), I can't easily clear this flag (the workaround can lead to l...

I'm trying to port code from STM32L4 to STM32U5.The STM32L4 code was using the LPUART, with a baudrate of 20k, clocked with HSI but in stop2 mode the HSI was stopped, it was able to wakeup and read incoming data. This configuration was using ~10uA.I'...

I spent many hours trying to make the SPI3 works through the use of the HAL but it was doing weird things (not clearing IRQ flag so ISR was continuously called).Then I found that SPI3 is limited to a size of 1023.I also found on this forum other peop...

In the STM32 ODE Function Packs page, the links to networking and security return an 404 error.

Thank you. I see the blue led now, there must be something wrong in my project.

I know that but with the unmodified code, the blue led never turn on.And with debugger, the code crash before going into low power.Would it be possible to have a binary file so i can know if i have a problem with my hardware or with my compilation ?

There is a macro named __HAL_DMA_GET_COUNTER(handle) that returns the number of remaining data bytes in the current DMA Channel transfer.

Would it be possible to provide me with .bin or .hex file of this example in transmitter mode so I can check if my problem come from hardware or software ?

I'm creating the project with example selector from STM32CubeIDE and i have verified that the code match the folder STM32Cube_FW_U5_V1.7.0\Projects\NUCLEO-U575ZI-Q\Applications\LPBAM\LPBAM_LPUART_TransmitReceive
