hello when i use UART Idle interupt with DMA on STM32H743XIH6 chip,i found ,the interupt function will run imediatly when HAL_UARTEx_ReceiveToIdle_DMA(&huart2, (uint8_t *)Uart2RxBuffer, 50)run,and this is my core code MPU_Config(); // SCB_EnableICa...
Post spread from STM32H745: No device found on target on a custom board Hi, and thank you for your previous answer and for pointing me to RM0399 / figure 22. I am quite new to the STM32H7 power configuration, so I may have misunderstood the datasheet...
Hello, I am trying to make a write into flash driver but I am having some issues.I know that the only way to write a 1 to the memory is by clearing the whole page, but I am having issues writing 0s.By reading the manual I encountered: Bit 2 PGERR: Pr...
I am implementing a high-speed, continuous UART loopback system using the GPDMA Standard circular mode on an STM32N6 series microcontroller. My setup involves autonomously linking UART_RX to UART_TX via GPDMA.The system is stable and the RX transfer ...
how to design the "NRST" pin about hardware?
I tried to follow this tutorial: How to build an AI application from scratch on the... - STMicroelectronics Community , could not figure out how to enable NPU RIF, so i skipped it. I tried to debug using the FSBL main.c, the blue led did turn on, but...
If have read the RM0456 and could not found a detailed description.If I switch the option byte DUALBANK to 0 single-bank mode, what will happen if I access a address which is normally supposed to be in bank 2? Do I get a memory access error?So is my ...
Hello ST Community team,On the DS11532: The title of the Figure 20 should be changed to avoid any confusion between figure 20 and figure 21.Also, the note under figure1 is not really clear since the STM32F767 TFBGA216 for example is not compatible pi...
Hi, I do not have a lot of experience with the STM32. I used other processors in the past like the LCP1768. We developed a custom bootloader to be able the load a new firmware into the uProcessor. In our current case, the STM32G474 is connected by ...
Hi Pascal, Any updates on our previous thread? When testing the same firmware with the EN pin pulled up, we are facing some issues during operation. After about 5–6 operation cycles, the system stops working until the MCU is reset. The issue still pe...
