Do you have an idea of why there is no support for USB in U-boot on T186 ?
Is it physically impossible, or is there a missing USB driver for T186 in U-boot ?
In tx2, there is no usb2.0 controller, so the only one that can used for usb is xusb controller. However, it requires xusb firmware and uboot cannot access it.
Indeed, the xusb firmware is not accesible by u-boot.
I asked the question on #tegra freenode IRC channel, and it would be possible to load the firmware from u-boot provided that the UPHY has been updated for u-boot before.
Hi hgouttard,
I am also trying to get u-boot on my TX2 to support the usb3.0 controller so that I can boot from a usb stick.
Did you get this to work? I don’t understand your last comment about “loading the firmware from u-boot provided the UPHY has been updated for u-boot before”.
