I am using the STM32H745 dual core MCU, and the CM7 can be run correctly, but the CM4 go to the Hard fault immediately, I set a breakpoint at the start of main() but can't capture it. Then I set a breakpoint at Reset_Handler in the startup file (st...
Hi, I have a Nucleo F439ZI board and I am running a custom bootloader and application on it. My Clock config =In Bootloader I am using HSE external crystal (ST-link MCO 8MHz) for all peripheral clock which includes 48MHz clock for USB OTG FS in DFU m...
Hey,im going to use the H743 MCU in ~400MHz core frequency with Free Artos operation system.one of my uses is to sample an analog signal with external ADC in SPI Channel.An interrupt to the MCU will inform “samplenow!�?.im trying to figure how much t...
Im using external interrupts on an STM32L412. I want the interrupt to run as fast as possible so I'm not using the HAL to turn off the request, rather I am writing directly to EXTI -> PR1, which needs to be written high to turn off the interrupt, but...
HiIn CubeIDE the temperature sensor stabilization time for my STM32G071 is defined by: stm32g0xx_ll_adc.h#define LL_ADC_DELAY_TEMPSENSOR_STAB_US ( 10UL)But in the Datasheet I see at least 15µs max for Tstart(ts_buf) and for Tstart itself its alrea...
Hi thereI am using a STM32F103C8T6. I defined this pins as External Interrupt:PB4 - GPIO_MODE_IT_RISINGPC13-GPIO_MODE_IT_RISING_FALLINGPC14-GPIO_MODE_IT_RISING_FALLINGPC15-GPIO_MODE_IT_RISING_FALLINGthe problem is that every time I SET/RESET PB4, it ...
We have tested UART3 with both Polling and Interrupt and working fine. But now we wanted to receive stream of 25 bytes each line continuously with DMA enable on UART RX.But We are unable to Receive any data with UART DMA. I dont find any example for ...
Flowing pictures have no hints to "Bufferable" attribute. Also in Cache column, some region have WB attributes which is just about caching capability; but we know that ARMv7-M architecture didn't consider any cache or cache controller inside the proc...
Hello;I want implement MPU unit in stm32F4. I have read ST documents about stm32F4xx, but did not find any thing about default attributes (write and read policies) for memory regions before enabling MPU. It means that: what memory attributes dose stm...
