Programming STM with SWV without nRST pin

Hello,I am programming STM32G491, while I need to use nRST as GPIO (MCO). I am using a code that you can see below. The problem is that when I am debugging a program, the debugger is disconected after HAL_FLASH_OB_Launch(); (this should reset MCU, am...

Resolved! Using SWD pins as GPIO

Hi,at the moment on the STM32U5G9 we have the SWD pins (SWDIO and SWCLK) set to DEBUG, but we would like to also use them as GPIO after programming. How do we switch them to GPIO at runtime? Thank you

Resolved! HAL_ADC_Start_DMA caused main loop to become blocked?

Hi, I am configuring the ADC in single-channel continuous conversion mode using DMA. However, once I call HAL_ADC_Start_DMA(&hadc, &AD_RES, 1), the main loop stops executing, and the HAL_ADC_ConvCpltCallback() function is not triggered.I noticed that...

RTCv2 coarse calibration remarks

While the Coarse calibration in RTCv2 is obsolete, in 'L1 and 'F2 it's the only method (and I know 'L1 is NRND, but it's still around and will be for years to come, if ST sticks to its commitment), and as long as it's mentioned in 'F4 it should be pr...

STM32 ADC and DMA with LL libraries

Hello everyone, I'm trying to sample some signals inside a timer ISR. I use all three ADC units of the mC (multiple channels in the first unit and 1 channel in each of the other two units) and I use software triggering and DMA transfer.This operation...
