NRST configured as GPIO to output MCO clock.In rare cases after power-on, the MCO clock is not output, although the program runs normally (e.g., printf messages are visible via UART).To increase the probability of reproducing the issue: the MCO pin i...
Hi,I'm currently working on an application for a STM32U575VI6. It's supposed to generate an interruption every 4 minutes and 9 seconds. However, it works only when I mask the seconds, and only work with minutes. The moment I try configure both and en...
I'm trying to get a USB virtial COM Port working on the STM32 Nucleo-H745ZI-Q. I've generated some minimal code to initialize the device on PA11 and PA12 and have tried connecting a four pin USB-C breakout board to wire GND, DP, DM, and U5V, as well ...
Split from Black Pill: Debugging STM32F103RCT6 in Keil Fails to Enter main()Hi @mƎALLEm , just about your "not genuine" statement:>- No "ARM " markingSame here on a F103 by STM , should be genuine, because its st-link on a F3-discovery board !>- The...
The datasheets for the new STM32U3 MCUs (375/385) list wake-up from stop3 on SMPS in uA (current), whereas for LDO the docs list the same specs in charge (nAs).Checking the U5 datasheet and the numbers are correctly listed in nAs units. However, the ...
Hello,I have an application which I would like to build on to of cubeMX generated HAL driver, but I came across strange issue that I am unable to keep RTC value on reset. Drivers part is as generated with cube using freeRTOS. system reset is triggere...
Hi,I am working on STM32 MCU, in my application once I start IWDG, based on certain event I want to freeze IWDG.Since my application is running, I don't want to reboot MCU.Once event processed, I want to continue IWDG without resetting MCU.Can anyone...
I am trying to use the bootloader of the STM32G474QET6 with USART to program my microcontroller. I have multiple questions regarding this but the first one is more about hardware. I have found in AN2606 that for the bootloader I can only use one of t...
Hi Everyone,I interfaced Nucleo F767ZI with W25Q256JV using SPI and everything was working fine. But due to time and speed requirements, now I have to shift it to QSPI. I have used example code of STM Document named "QSPI_F769_discovery_flashloader" ...
Hi all,I'd just like to report an error on the reference manual for RMSTM32F411 (RM 0383 Rev 3).The error is located on page 471, on section RTC Register Map.The table showcase all registers for the RCC and miss the entry for RTC_SHIFTR (located at a...
