Bits 6:4 OC1M: Output compare 1 mode (Frozen - The comparison between the output compare register)
The output of TIMX_CH1 and TIMx_CH1N is decided by previous value before bits 6:4 changed to Frozen mode?

STM32N6: Debugging Issues with External Flash and RAM Debug in FSB & App
Hello,We are using the STM32N6 series MCU in our project and encountering issues during debugging. I’ve attached a screenshot of the error message we are seeing.We followed the steps outlined in this guide:https://community.st.com/t5/stm32-mcus/how-t...
Resolved! Wrong (?) description of ADCs in STM32H5E5/F5
In ds H5E5 is given: 3x 12b ADCbut on selector is shown:...so secret 3 x 16b ADC there - or error in table ?
Resolved! CAN FD network normal mode does not work with NUCLEO-C092RC boards
Hello everyone, i want to build a CAN FD network with three NUCLEO-C092RC boards. So far i can transmit frames, as i can see on an oscilloscope. But the moment i connect TWO boards, the interrupt is not triggered. My code should activate user LED2 ...
STM32N6570-DK – FSBL Peripheral Configuration, Multi-Layer Execution & External Flash Loader Issue
I am currently working on the STM32N6570-DK board and need guidance on FSBL configuration, multi-layer project structure, and external flash programming.Issue 1: FSBL Peripheral ConfigurationI enabled multiple peripherals in FSBL:USART1, I2CBSPXSPI1,...
STM32G0B1CET6N VDDIO2
Hello I'm trying to wire up the STM32G0B1CET6N and I don't know how to use the VDDIO2 pin. What is it for and how should I wire it?
Resolved! Can TIMx OC DMA events be used to load DACs from memory?
I want to vary the duty cycle of two adjacent DAC values of an STM32G473. I am using DAC1 channel1 and channel2 for the output. I want to load DAC1s DHR12Rx registers via DMA when TIM3 hits output compare values. I set up a memory to peripheral tra...
Can backup registers persist when VBAT drops enough to stop RTC?
I'm working with the STM32G4 series and using the backup registers to store time data that persists across power cycles. I have a question about VBAT brownout behavior that I cannot find explicitly documented in RM0440 or the datasheet.Background:Bot...
Resolved! Reset reason, detect debug session
Hallo,is it possible to detect in my code whether it was just loaded and started under debugger? The code should behave deifferant as usual because flash loader writes into RAM and .noinit section is modified because of this.I have already checked RS...
Resolved! STM32G431: Application doesn't start after system bootloader finished
This is one of those issues where I can hardly figure out what to seach for...I have a board (with an STM32G431) where I can activate the BOOT pin with a switch, to start the system bootloader. This allows the customer to upload a new application ver...
