![]() ![]() return usart_write(platform_get_console(), (u8 *)ptr, len) įinally I start the trace in the SWV console in the IDE but I get no output.Īny idea what I am missing ? What about the core clock of the SWV ? I'm not sure what it corresponds to. If (((ITM->TCR & ITM_TCR_ITMENA_Msk) != 0UL) & /* ITM enabled */ I've modified my _write function as follows: static inline unsigned long ITM_SendChar (unsigned long ch) #write 1 to ITM trace privilege register to unmask Stimulus ports 7:0 # Write 0x1 to the ITM Trace Enable Register to enable the Stimulus Port 0 Check in your FW if you are invoking low power mode of the CPU. # Write 0x00010005 to the ITM Trace Control Register to enable the ITM with Synchronous enabled and an ATB ID different from 0x00 The problem is in the low-power mode When CPU core clock is halted the debugger connection fails and debug session is halted. # Write 0xC5ACCE55 to the ITM Lock Access Register to unlock the write access to the ITM registers # Enable Debug connection in low power modes (DBGMCU->CR) + TPIU for SWV ![]() # if the code is not located at default address and does not run by reset. # Reset the chip to get to a known state. I'm not sure it is necessary since TrueStudio/Eclipse allows to setup SWV from the GUI but seems easier this way: # Set character encoding The STM32 Nucleo-144 boards do not require any separate probe as they integrate the ST-LINK/V2-1 debugger/programmer. I've modified my startup script as described in STM32L4 reference manual as follows. On Atollic I modified my Debug Configuration to enable SWV with a core clock of 80MHz. However they can be a good starting point to start programming your Nucleo board. These projects are thought as companion examples to my blog posts where I describe in depth how to use them. This repository contains basic templates for the STM32Nucleo-F4 developing board from ST. ![]() I want to migrate to printf using STM32 ITM. Eclipse project templates for STM32Nucleo-F4. Until now I was using printf through UART, thanks to the Virtual COM port. I am developping a Firmware on various STM32L4 Nucleo boards with Atollic Truestudio IDE (basically Eclipse). ![]()
