Hi,Because the STM32l5 not support "__HAL_SYSCFG_REMAPMEMORY_SYSTEMFLASH", Please tell me how to change the program entry point without program on-chip flash.ThanksQiZhang"void AppEnter(){ #define SYS_MEM_ADDR 0x8020000 __HAL_SYSCFG_REMAPMEMORY_SYSTE...
Hi,i'm trying to send data from an stm32f446-nucleo board ( as a master ) to an stm32f469-disco board ( as a slave ) but it is not working correctly,PS: Each board is connected separately to a USB Port from PC.MASTER Code :int main(void){ SystemClock...
I didn't see PA11 and PA12 in this kit
After reading the section about Flash in RM0433 I am till a bit in doubt of the sequence of events during flash programming.This is important because I need to know that certain write operations are complete (such that the update is reflected even if...
Hello,we had trouble with a batch of STM32F103CBT7 processors. I have read a lot about counterfeit CPU's. I had the Error 18 in CubeIDE and 5 out of 1000 IC's did not work as our stock ones (STM32F103CBT6). The UID of one of the chips is UID0= 0x0047...

hi we want to debug from the external memory interface. Actually my code size is more than internal RAM memory, so we want use external memory jtag debugging. is this external memory debugging possible? if possible what is procedure ?
I have an idle interrupt, on usart2 handle;void USART2_IRQHandler(void) { /* USER CODE BEGIN USART2_IRQn 0 */ /* UART IDLE Interrupt */ if(__HAL_UART_GET_FLAG(&huart2, UART_FLAG_IDLE) == SET) { __HAL_UART_CLEAR_IDLEFLAG(&hu...
Hello,I have three interrupts,One from EXTI4, which has NVIC_IRQChannelPreemptionPriority = 0One from EXTI9_5 which has NVIC_IRQChannelPreemptionPriority = 1One from TIM4 which has NVIC_IRQChannelPreemptionPriority = 2For testing purposes, EXTI4 and ...
Hello, what's the difference between the "Normal" and "Circular" modes of the STM32 DMA ?As far as I understand - "Circular" will write to the first address, auto increment the address to the next one until the last address is reached and then return...
