Resolved! Which register can set the timeout for the FMC's NWAIT signal to prevent a crash?
HiChip：stm32h723Peripheral:FMCConfiguration:FMC_NORSRAM_DEVICE , FMC_NORSRAM_EXTENDED_DEVICE;FMC_ACCESS_MODE_AFMC_ASYNCRONOUS_WAIT_ENABLEIf the extended device(eg. FPGA) do not assert NWAIT，the program on stm32h723 will crash. I want to know which re...
Setting up pins for alternative functions of STM32F411 MCU
Hello,STM32F411 microcontroller.Where can I find what mode (input/output or pull-up/pull-down) to configure the GPIO for alternate functions? For example, for UART or SPI and so on.For example, for STM32F103 microcontroller, there are tables that hel...
stm32u5g9 dcmi double buffer linked list
Hello Using a STM32U5G9NJHxQ.Using a 646x480 1byte per pixel monochrome Dcmi camera --> 310080 bytes --> 77520 words (32 bits) --> according to AN5020 6.4.8 this means Double buffer mode for medium resolutions, continuous capture in my case.Based on ...
Debug Trace ETM - STM32H5, Keil
Good morning, I am trying to debug an STM32H573II with ETM, but I cannot get it to enter that mode.Debugging without trace with SWD works correctly. I have used this environment: - uVision 5.42- ARM Compiler 6.21- STM32CubeMx 6.14.1 I have performed ...
Resolved! Able to use printf on uart3, but not on uart2
Hello, so I was originally using printf with uart3, and that seemed to work fine. The characters were being printed as expected on a PuTTY terminal that I was using. I was using the following code:/* USER CODE BEGIN PV */ UART_HandleTypeDef *uartHand...
Resolved! I3C:direct RSTACT not working as expected
Setup: NUCLEO-H503RB with X-NUCLEO-IKS4A1, using STM32CubeIDE. To familiarize myself with I3C, I am playing around in this setup and have some source code which causes I3C interaction between the controller (Nucleo board) and two targets (daughter bo...
STM32H7 QUAD SPI DDR timing
Hello,I have a STM32H75x design and suffer from read errors in DDR timing, no matter if run at 50MHz or slower.It seems that the data hold time of 1ns the H7 is violated. The data output hold time of the SPI NOR MX25L12845 flash is 1ns, which seems t...
Error: registers may not be the same -- strexb r3,r2,[r3]'
Hi,I am currently using the following microcontroller (STM32F100C8T6B) in my design. I am using the STM32CubeIDE and I trying to build the project, but I am getting the following compiler errors from the "core_cm3.c" fileError: registers may not be t...
STM32L476 Tamper Detection – False Trigger Risk During VDD to VBAT Transition?
Hello Experts,I'm using the STM32L476 in one of my projects, with the main system powered at 3.3V (VDD), and a 1.55V coin cell (Murata SR621SW) connected to VBAT for RTC backup.The tamper pin (PC13) is connected to a normally closed (NC) anti-tamper ...
