I found some information about the firmware upgrade mode.
On the emmc flash page they have a picture what pins to connect to enable firmware upgrade mode:

And if you go to the datasheet there is a note about uart/usb update pin:

on page 4 the note says:
BOOT-SEL2: 0 USART_UPGRADE; 1 USB_UPGRADE
It looks like it is 1 by default so you need to connect the pin to gnd to enable usart upgrade mode. The pad the pin is connected to is called TP3 and is close to the pins for entering firmware upgrade mode. The precise location can be found on page 1 on this pdf:

All these pdf can be found at the bottom of this page
