Hi everyone,I write a function to start all other functions without any parameter like Start(); in while, but in this funciton I write different function like thisvoid Start() { if(huart->Instance == USART1) measure(tx1_buffer); ...
Hi,I'm using a Wifi/BT module with CYW4343W chip on a custom board with STM32MP157.When booting the system, the driver is loaded correctly and dmesg log shows[ 1.089865] 4000e000.serial: ttySTM1 at MMIO 0x4000e000 (irq = 24, base_baud = 6250000) i...
Hy i wanted to ask how i can set the clockspeed on my Device tree so the USART3 will work with 10MB/s my device tree looks at them moment like this:&usart3 { pinctrl-names = "default", "sleep", "idle"; pinctrl-0 = <&usart3_pins_b>; pinctrl-1 = <&usar...
Hello, I have done the modification in the device tree related to inclusion of usart3 as per 3.3.1 Activation of a USART or UART instance in https://wiki.st.com/stm32mpu/wiki/Serial_TTY_device_tree_configuration&usart3 { pinctrl-names = "default", "s...
Hy i am using the usart3 from the STM32MP157A-DK1. i orientated myself on the USART driver (https://elixir.bootlin.com/linux/latest/source/drivers/tty/serial/stm32-usart.c).butwhen i want to initialize theport I get following error code “Rs453Network...
I have stm32mpdk2 board and trying to interface a uart based peripheral ( nfc) .I have connected Tx , RX , Vdd, GND > pin (12,8,1,6) .tty driver is already enabled in the kernel. and the peripheral on powering up shows the init sequence correctly(led...
Hi, all.I use STM32MP151CAA3.I want to transmit USART data by DMA with HAL Driver.I’m trying to use HAL_USART_Transmit_DMA () function to transmit data.In the case of STM32F437ZI(using STM32F4xx HAL Driver), when calling HAL_USART_Transmit_DMA(), USA...
I use the UART4 like the following initialization.void uart4_configuration(void) { GPIO_InitTypeDef GPIO_InitStructure; USART_InitTypeDef USART_InitStructure; /* enable usart clock */ RCC_APB1PeriphClockCmd(RCC_APB1Periph_UART4, ENAB...
