Slaa452c demonstrate how to update firmware by USB, but it's working on PC.

Can I update firmware by USB disk? Is there any reference example? Thanks a lot.

Hey Daniel,

What do you mean by USB Disk? Do you mean like a thumb drive?

MSP430F5xx MCUs can only be USB devices, they do not offer USB Host or Hub functionality. They must be the peripheral device.

This means that they couldn't connect with a USB thumb drive. MSP430 must be connected to a USB host, such as the PC, and updated as highlighted in that App Note.

Let me know if this is what you meant.

Thanks,

Hi JD,

Thanks for your reply.

If MSP430F5xx and F6 xx series can only work as peripheral device.

It's not convenient to update firmware because it must has a PC or MCU with host USB to do this.

Hey Daniel,

That will just depend on the application. If they are already using the built-in USB, then it will be as a peripheral device and the host will have the ability to update it.

The other common BSL interface offered on some MSP430F5xx/6xx is UART.

Thanks,

JD,

Thanks for your information.

My customer is only interested in updating firmware by USB thumb drive, because it's easy to carry.
