Hello, I am wanting to do a firmware upgrade on a STM32H7 processor through a USB connected to another microprocessor(Such as an Eval board). Are there any examples or libraries for firmware that will run on the Eval board which will upgrade the STM3

Not sure there is a DFU HOST, but there is a DEVICE

You could perhaps have the donor device be an MSC DEVICE, and use the FW UPGRADE firm READ file/data content that way.
