Hi! I'm having the same problem and the boot selector is in TF mode.

Any idea?

Regards, Gonzalo

I think a boot selector of a board is "boot from NAND".
the explanation of a boot selector of a board is here.

Is your SD card 8 GB and class 10? It is must being class 10, otherwise it won't work. Be also sure about the boot selector. Beyond that, are you trying the communication via serial using a USB-TTL converter? If so, remember to set baud rate 921600 on the PuTTy for example.

Any doubts come over again, good luck!

Hi. Yes, i am using SD Sandisk 8G Class 10 (and a lot of other SD card recommended in other thread). The boot selector and switches are on the right position.

The communication is working because the serial terminal show the same output reported by NinjaPenguin (in the first post of this thread) and boot up freezes  (the last line is EMMC boot ...)
