Hi,
I work for a company that produces low-cost consumer electronics that use
8-bit microcontrollers. These have the standard 8-bit whistles, like SPI,
SCI, etc.
We've kicked around the idea of allowing customers to re-FLASH our products.
The re-FLASHing would be facilitated by code we write that runs in the
microcontroller and reprograms a portion of the FLASH.
We have a handle on digital signatures and what would be required to prevent
a customer from "forging" a software load.
However, what is required to implement a USB interface in the product (for
an 8-bit microcontroller), and what is required as far as a driver on the PC
side? The goal would be that we distribute a re-FLASHing application to the
customer that runs on the PC. They would run this application with a USB
cable connected from the PC to our product.
What all is required (hardware, driver development kits, etc.)?
Thanks for all.
MAX3240 seems like a good option. I'm planig to use in a project. It
comes with a evaluation board to start with.
