Force USB Recovery Mode
The Elroy carrier supports flashing the TX2/TX2i/TX1 module over USB 2.0 using Port B. A standard
USB-A to USB-A cable is required to connect it to the flashing system. Note that you should leave the
USB cable unplugged until after the TX2/TX2i/TX1 is put into recovery mode.
To flash the TX2/TX2i/TX1, first ensure the unit is powered down. Next, connect pins 6 and 20 of the
System Header together with a jumper wire, then power on the unit. The jumper wire can be removed after
applying power. Connect the USB-A to USB-A cable from a free USB port on the host PC to the USB 2.0
port on the Elroy. The TX2/TX2i/TX11 can now be flashed using the standard NVIDIA flashing tools.
