yes ! pin on chip 25 - Rx, 26 -Tx
not use "External RS-232 transceiver or UART circuitry"
cp2102 only

Yes correct RX 25 connected to popcorn UART0 PIN 5
26 - TX to popcorn UART0 PIN 6

And additionally +5V and GND.

but do not works. Any clue?

5 Rx <--- Tx (26 pin)
6 Tx ---> Rx (25 pin)
10 GND - GND
not use additionally +5V

This adapter won't work with console port Popcorn, as it USB-RS232 adapter. You should use USB-UART adapter on chip CP2103 or RS232-UART adapter on chip MAX232.

In the datasheet of that chip is that it is an UART - USB Bridge.

Probably that you also are right, and on CP2102 it is possible to construct the console adapter, but at us such experience isn't present, adapters which were tested by us in the majority are made on CP2103. To that ready decisions from mobile phones (data cable) have been used.

Short TX and RX on your adapter. In the console program you should see all typed symbols. If it isn't present - your adapter doesn't work.

Yes i see the typed characters in the terminal if i short TX and RX pinouts on the adapter.

Maybe you did not correctly connect the TX and PX, swap them :wink:

Второй вариант подойдет абсолютно точно, поскольку он на чипе PL2303. Насчет первого, на чипе CP2102, ничего сказать не могу, поскольку сам таким никогда не пользовался.
