On the other side of the PCB there are 4 test points:
- TP1 GND
- TP2 ? (probably Vcc)
- TP3,4 serial console
The serial interface is 3.3V TTL levels (need USB cable and/or level converter to connect to a PC). Settings are 57k6 8N1 no flow control.

u-Boot[]
For TFTP from u-Boot the AP has to bo connected to a 10/100M switch (does not work neither on a 10/100/1000M switch nor on a 10M hub).
For FW recovery use option 2 ("Load system code then write to Flash via TFTP.") to download the original FW image (currently U300ARAEN_2.4.15.bin from U300A_EN_2.4.15.zip).
