Board programmingĭownload the “TP Python” folder on the Windows Desktop, available on the drive: TP_Python.zip We will be able to update the firmware by USB. These modifications allow the STM32WB55 to be configured in bootloader mode. Here is how the kit should be configured: Connect a micro USB_USER cable to the port below SW4.Move the SWDIO jumper and place it on pins 5 and 7 of the ARDUINO CN7 connector.These steps are to be carried out by the teacher with administrator rights under Windows 10 and this for each NUCLEO WB55 board used in the practical work. If you are using USART(RS232) option, Take a precaution about signal voltage levels. You should identify the Bootloader to Host connection interface such as USART, USB etc. Step 4: Identify the Bootloader Interface įor Bootloader, we can use following settings :Ī: nBoot1 or FLASH_OPTR = nSWBOOT0 or FLASH_OPTR = 1 using STM32 ST_LINK utilityī: BOOT0 =1 by using a jumper between BOOT0 (PH3 pin) and VDD I discussed about various Boot configuration options. I was able to find the STM32 BOOTLOADER in Windows Device Manager after checking View->Hidden Devices Step 2: Installation of Bootloader DriverĪfter installing STM32cube programmer, I executed the STM32Bootloader.bat file, given at location below, in CMD window with admin privileges.Ĭ:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\Drivers\DFU_DriverĪnd rebooted my PC. Several installation issues reported for this in Windows 10. The USB interface used DFU(Device Firmware Upgrade) protocol. In case of application running in the target, You may use ST-LINK interface. So if bootloader is running, Use bootloader specific connection interface for communicating with target. This utility can connect to device using both ST-Link and bootloader interface. This is a Free software utility available at STM32cube Programmer. I have installed STM32cube Programmer on Windows 10 host. Step 1: Installation of STM32cube Programmer STM32 bootloader supports many interfaces such as UART, USB, CAN etc to communicate with host PC and host based software can program the device without debugger interface. Here I will share the method I tried for STM32 Nucleo-L4R5ZI board. How to Enable Bootloader in STM32 Nucleo board ? Additionally, You may same some power as well by using UART interface. STM32 devices have inbuilt bootloader which can be activated based on certain hardware & software configuration. Similarly we need some bootloader in embedded system as well which can be used to update system software in the field. No, Think about the situation when your hard-disk crashes, BootROM plays an important role in that case. That will fulfill the basic application programming requirement. One can find equipment to do mass programming of STM32 devices. The reason is obviously to reduce BoM (Bill Of Material) cost. But no one will prefer to integrate such debugger interface in final product. This part itself one small embedded product with MCU, USB interface and other components. The ST-LINK part was discussed during STM32 Nucleo-L4R5ZI board introduction. So far we have used ST-LINK in all the STM32 related material. Explanation of programming options, Bootloader & DFU driver installation in Wiindows 10 with Nucleo-L4R5ZI board. In this article, We will discuss Installation of STM32cube programmer.
