Histudying the DMA of the STM32F407 MCU, I came across Figure 1: System architecture.It says DMA_PI for GP_DMA1 but DMA_P2 for GP_DMA2.I reckon that DMA_PI is a simple typo and should be called DMA_P1 and stands for the DMA peripheral bus.Would you a...
Hello everyone,I'm developing a firmware for an STM32F767 and I have a problem that happens randomly and I can't figure out why. From what I could analyze looking at the stack I think the problem comes when doing a sprintf and I have the hypothesis t...
Hi,From RM0090 (Rev 19 - February 2021), page 1393:"Host enumerationThe application issues an USB reset (single-ended zero) via the USB by keeping the portreset bit set in the Host port control and status register (PRST bit in OTG_HS_HPRT) for aminim...
Hello There,I'm using STM32H7A3 and facing a weird issue with HAL_UARTEx_ReceiveToIdle_IT() API.STM is connected to Cellular Modem via UART. When I turn on the modem via some GPIOs, initially it throws some init data. But when I call HAL_UARTEx_Recei...
To,Sir or MadamI am making a embedded system with MCU STM32F103RETxLQFP64. In this MCU pin PC10 and PC11 is multipurpose pin. I use it for UART.In project, PC10 and PC11 is used as GPIOs. I change functionality of pin. I used pin PC10 for UART4_TX an...
Hello there! I am using the B-L4S5I-IOT01A board. After setting up the AWS process, I have opened tera term to configure the device. After I configured the tera term once I press the reset button on the board, no information is being displayed on the...
Hello,I have a question related to the GPIOs PC13/PC14/PC15. Due to the fact that in my project I am running out of the other GPIO pins I have a question related to those pins above. I know that those pins have limitation to max 3mA sink current so d...
Hi. I am writing a bootlloader application that can erase, rewrite, and jump to a user application.As a starting point, I want to make sure I can erase the user application, but the erase seems to have no effect. My sector erase code is below.uint32_...
Dear,Started with the FreeRTOS example I am trying to communicate over uart with a sim7600G. I have setup my usart2. I am able to send data but the returned value contains only the data sended and no response from the sim7600G. I have tried with an e...
