Currently, on the STM32G474, I am able to perform on-the-fly flash operations and interrupt vector relocation using BF_MODE and VTOR. However, I have encountered an issue: when a function is placed in RAM using the ramfunc attribute or located in CCM...
IssueHigher ambient temperatures cause communication malfunctions with XSPI memories.DetailsOur design is heavily adopted from STM32H7S78-DK which also has the same issue described below.The application uses memory-mapped mode for both Flash and RAM ...
Hi All!I try to use 2 pieces of IS66WVO32M8 PSRAM with multiplexed OSPI ( only the NSS pins not shared ) with STM32F585 in memory mapped mode.Previously, I used 2 pieces of APMemory's APS12808L in memory mapped mode without any issues.I reconfigured ...
hi ；During the operation of STM32H723VGT6, the constant input bus error and hardware error interrupt occurred, and the clock is 280M. The PWR_REGULATOR_VOLTAGE_SCALE1 is unstable. The clock configuration __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_...
Hi Im Lalin, Im using STM32L433RC-P MCU for learning.Im facing the issue in reading the data from ADC.Im not getting any error too.Below are the source code attached.Kindly help me to find the solution for this.Note that im using uart.c for debugging...
I am using the STM32H742 MCU.Currently, System CLOCK is set to 480 MHz and APB TIMER and AHB maximum CLK is set to 240 MHz.However, the maximum frequency of TIMER and GPIO cannot exceed 25 MHz, so what should I do to make it over 50 MHzAttached is th...
Hello,I have a STM32G0B1KBU3N MCU for my USB-C PD board. I am a new with this so learning. I am currently finished assemble my own PCB and have some issue with programming the controller. I can program controller with ST link V3-minie but have Zero l...
Hi i'm using STM32F411RE. I've been reading data from ADC IC using I2C communication. It's 400Khz, and I'm reading using DMA. By the way, if another interrupt with high priority occurs during I2C communication, it runs that interrupt during I2C commu...
Hello,according to this document https://www.st.com/resource/en/application_note/an5337-guidelines-for-estimating-stm32h7-mcus-lifetime-stmicroelectronics.pdfthe expected lifetime of a STM32H7 mcu depends on the parameters Tj (junction temperature), ...
Hi STM32 community.I'm working on an embedded system which uses a RK3399 CPU (running Linux, functions as a USB host) and a STM32F302CC (Runing FreeRTOS, functions as a USB device). This runs on a custom motherboard. They communicate with each other ...
