Can't access STM32L552 after setting SRAM2-RST to 0

I've been trying to run the SBSFU example from STM32Cube_FW_L5_V1.2.0.The option bytes I set initially were:TZEN=1DBANK=1 (was already 1)SECWM1_PSTRT=0x0 and SECWM1_PEND=0x7fSECWM2_PSTRT=0x1 and SECWM2_PEND=0x0.That allowed me to load SBSFU bootloade...

Resolved! Max current possibly sourced from a DAC pin?

Hello. I would like to know how much current a DAC pin is able to source. The STM32G081 datasheet indicates "Output current sourced by any I/O and control pin = 15mA". Is this 15mA also an upper limit to a DAC sourcing pin? The STM32G081 datasheet al...

Resolved! TIM2 freeze on ARR register value changed STM32H743ZI2

Hi. I'm working on project where I need short pulses with precise periods generated in audio ranges (10 - 20kHz). So I decided to choose TIM2 and using it in PWM mode. I'm using HAL library and configuration code generated by CubeMX:void MX_TIM2_Init...
