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. Your device has a new Firmware on it.In this article, We will discuss Installation of STM32cube programmer. Then press the lower „Choose…“ button to select the generated DFU file and press „Upgrade“… That’s all. Just use the DFU file manager that was installed along with the DFuSe Demo Software to create a DFU file out of e.g. To create a DFU file is well described in all the other resources on the web. Welp, as soon as the device showed up, also the DFuSe Demo Software recognized the device and stepped into life. A different device showed up just a goup above the previous one: „USB Controller“. What the heck?Īfter some digging through the web, I found different suggestions and problem solutions, but none of it worked.The simple solution was, to uninstall the device’s driver in „Device Manager“, unconnect and reconnet again. But hey, it could not find an appropriate device. I was really happy about that and started the DFuSe Demo Software from STM. When I connected a piece of custom designed hardware with my laptops USB port with BOOT0 tied to VCC, it immediately showed up a new USB-Device called „STM32 Bootloader“ in group „USB Devices“. The tool I tend to use can be found here at STM’s site. I’m not sure, if I’m simply a problem magnet or why some stuff does not work as described… Here is another case.
