Hi Peter, I used to work for Synopsys, who is the vendor for the usb-otg IP, and am the author of the dwc2 driver in the Linux kernel (actually just a port of the vendor driver to Linux). So I am pretty familiar with the hardware. But I had to give up all the documentation when I left Synopsys.

Hi John, Thanks for the tips! I found an issue when testing with the usb-storage device, so I will work on fixing that, and then think about how best to split up the patches. Thanks, Paul On Mon, Mar 9, 2020 at 7:23 PM John Snow wrote: > > > On 3/6/20 7:34 PM, Paul Zimmerman wrote: > > Hi

Any interest in dwc-otg (aka dwc2) device emulation? For Raspi 3 and below.

Hi Folks, I have been working on an emulation of the dwc-otg USB controller (host mode only for now), as implemented on the Raspberry Pi 3 and below, and on numerous other embedded platforms. I have it to a point where it works pretty well with the dwc2 driver in the mainline Linux kernel, and
