Hi Marek, This was tested using v1 of this series after applying all patches to the base commit referenced in that version's b4 metadata, see [1]. Tested on a Rockchip RK3576 based board with two DWC3 controllers as follows: - Set one controller to gadget mode, the other to host mode via DT - Confirmed no crashes or warnings in U-Boot at boot - Initialized the host mode controller via console commands with a USB 3.0 flash drive connected via a hub - Initialized the gadget mode controller via `ums`, pointing it at the flash drive connected to the other controller - Connected the gadget mode port to a Windows computer - Confirmed no crashes or warnings in U-boot - Confirmed the device is recognized as USB mass storage by the Windows computer - Mounted the USB mass storage device on Windows - Confirmed correct partitions and size - Confirmed correct data - Confirmed reading and writing works - No crashes or warnings in U-boot - Safely removed the device on Windows - Stopped `ums` in U-boot, confirmed no crashes or warnings while stopping This worked better than the then-current U-boot master branch, which had trouble properly resetting the controller at boot, resulting in non-functional gadget mode.
