Programming the microcontroller in a USB flash drive

Question

Programming

Good night, Khabrovites!

I'm wondering if it is possible to program the microcontroller in a USB flash drive directly via USB?
If so, I would be very grateful for links to software and manuals.
I myself tried to open a flash drive through a hex editor, followed by disassembly, but I'm not sure that I'm digging in the right direction.

Thanks in advance!

Answer 1

In general, you can. There is, for example, a website flashboot.ru, where a database of the type “PnP flash drive ID - controller brand” is collected. You can look for datasheets for these controllers. If there are no datasheets, then in the same place people post underground tools for flashing these same controllers. You can also reverse the firmware. It is clear that there is no benefit from this, for homemade products it is better to buy something like Arduino. And as an exotic hack, it might work.

Answer 3

no, usually not.
what you open is the contents of the flash memory, not the ROM of the microcontroller.
