MSI PLL-mode is crashing with use of Stop modes at cold
I'm using STM32L486 at 2.5V.The MSI auto calibration feature (aka PLL mode) is crashing at cold temperatures with specific usages of Stop mode. When it crashes, it drives MSI to its minimum frequency for the selected range. For example, the 24 MHz ...
Is priority gauranteed to make two DMA transfers initiated by the same trigger arrive at a static destination address in order?
I need to process samples from two different ADCs by transferring their samples to the FMAC via DMA. This is done by writing repeat values to FMAC->WDATA. Both ADCs have the same trigger and I want to insure one ADC's value arrives before the other. ...
Problem in single conversion mode in ADC
Hi, While implementing a single conversion process for the Analog-to-Digital Converter (ADC) via register-level programming, the debugging phase yields a consistent output of zero, irrespective of the input. This anomaly persists even after the ADC i...
Is This Safe !! DMA??
Hello all I am interfacing various peripherals on the STM42F446RE, SPI, I2C, UART etc, and in the process i'm choosing to use the DMA controller.when configuring various 3rd party ICs some may have many registers to setup, Rather than use global arr...
Resolved! FMAC writes YEMTPY and UNFLs bit incorrectly after pre-loading X1 coefficients with no reads or executes taking place. Why?
I am using the FMAC for the first time and I am seeing strange behavior after preloading data to X1. I'm pushing 16 items to WDATA via a memory to memory DMA transfer. The buffer size is 16, so X1full should go high when it finishes. It doesn't. I pl...
Resolved! STM32U5A5 application doesn't run after power cycle but runs from debugger after flashing
Hi,I'm developing a new application for the STM32U5A5 processor. The application runs correctly if I program (flash) and debug with the JTAG/SWD debugger. Even after disconnecting the debugger, the application still runs, and it is possible to re-pro...

Issues with Nucleo STM32-H7A3ZI-Q and DCMI with OV5640 camera
I've been trying to connect to multiple OV5640 camera sensors from different brands and even STM32's official board B-CAMS-OMV on the STM32-H7A3ZI-Q nucleo board and have had no luck with it whatsoever. Does ST have any projects that are built off ...
LPTIM1 CNT = ARR in half the time
I am making this code which, on an interrupt, is supposed to wake the system from STOP mode, put it into low powered run mode, and run LPTIM1 for 1 minute before triggering a flag and going back into STOP mode. I have PSC as 128 and ARR as 60962, so ...
