![]() The following is the code I generated using STM32CubeMX. If anyone solved this problem, I would appreciate it if they shared it. But nevertheless I can't see the print message. I only made use of USART3 and confirmed that there is syscall.c in it. However, I generated the code using STM32CubeMX. If (HAL_UART_Init(&UartHandle) != HAL_OK) ![]() The following is UART example code from STM32CubeMX.ĭirectory : STM32Cube_FW_F7_V1.15.0\Projects\STM32F746ZG-Nucleo\Examples\UART\UART_Printf. same day shipping, fast delivery, wide inventory, datasheets & technical support. If I copy the syscall.c, then it works fine in UART example. The STM32 Nucleo-144 board provides an affordable and flexible way for users to try out new concepts and build prototypes by choosing from the various combinations of performance and power consumption features, provided by the STM32 microcontroller. Buy NUCLEO-F746ZG - Stmicroelectronics - DEV BOARD, ARDUINO/MBED NUCLEO. I searched this issue and found that many users were having a hard time.įinally, I found the solution for UART example which is in STM32CubMX from the following web site. I don't have oscilloscope and I really want to see the print message through hyper terminal like a realterm. ![]() USART3 connected to ST-LINK to support the virtual COM port, but it didn't work now. I'm trying to use the UART3 in NUCLEO-F746ZG with TrueStudio. ![]()
