Hi, I need to update the firmware of my MCU from the UART. I mean without physically touching the BOOT pin, but only via serial commands (classic FW update of a product).
I'm not an expert, but I tried searching on the internet and I saw that for these things it is necessary to write a bootloader. It doesn't seem impossible, but for a non-expert it's not exactly simple.
What I wanted to ask is, I think this is a very common need among users, has STM created anything official to support this feature? Is there something already given and official that I can use without necessarily writing my own custom bootloader? Maybe even supported directly in CubeMX.
I've seen that there are dozens of amateur/community bootloaders available, but not knowing how to write it, I can't even evaluate whether it's done well or whether it's suitable for my application, which is why I'm looking for an official STM solution.
