STM32WLE I2C-Master unable to get DMA to work

Hi,I am very new to the whole STM32 environment.I recently ordered an STM32WL-Board with which I wanted to create a bare-metal code for an I2C Master transmission via DMA. I was able to get it to work without DMA but I struggle with setting up the wh...

Trying to reboot STM32WLE5 after flash UART mode

Hi all,I've adapted stm32loader python script to working with STM32WL familly, https://github.com/copterust/stm32loader/blob/master/stm32loader.py .It's working I'm able to flash, read, erase flash. I can flash my firmware. But for now I'd like to re...

STM32WB, CPU1 stuck waiting CPU2 at init

Hello,I'm using the ble_ota bootloader that I have adapted to the STM32WB55CGU package and it advertise fine at power up and boot the app correctly but when I’m resetting from app the bootloader is stuck at the ble stack initialization (SHCI_C2_BLE_I...

Resolved! STM32WB5MMGH6 consuming to much current at Stop 2 Mode

I'm using an STM32WB5MMGH6 and it's consuming too much current at Stop 2 Mode.The existing BLE connections are closed and advertising is stopped. All unnecessary peripherals, gpios and interrupts are disabled. The system clock is changed to MSI at 1M...

Resolved! More bugs in CubeIDE code generation for STM32WL33

When generating code that uses the CMSIS OS V2, it appears that a template directory gets included in the generated code. causing massive linker errors. The offending directory is Drivers/CMSIS/Device/ST/DEM32WL3X/Source/Templates. Removing it gets r...

Resolved! More SWDIO/SWCLK bugs for STM32WL33 generated code

I have found another bug in SWDIO code generation. I previously reported that no code is generated for SWCLK, but if both are relocated, SWDIO is also incorrect. The .Alternate uses a define of GPIO_AF1_SYS, which does not exist in stm32wl3x_hal_gpio...

Resolved! Timer TIM2 does not work when BLE is initialized in STM32WB55.

Hello.I am facing a problem: timer tim2 is not working with initialized ble and tasks and timers HW_TS (button and LED processing). Just in case, I checked that TIM16 is working, but it is busy with another task, so I can't use it. I've tried many th...
