I took a while to errors when playing movies from the player (lock screen, reboots). After updating the firmware, still not working.( Same reboots, lock screen)
I open the media player and I have seen that has a UART port.
1 Ground 2 UART_RX0 3 UART_TX0 4 UART_RX1 5 UART_TX1 6 VDC 3.3v
I tried to connect the port UART with connector Sitecom CN-104 v4002
This mounts a PL2303 chip. I had problems with windows 7 installing driver. I tried Windows XP and GNU/ Linux. In all cases the same problem (Weird characters) in Putty program.
UART DB9 GND PIN5 (GND) UART0_TX0 PIN2 (RXD) UART0_RX0 PIN3 (TXD)
I connected with putty.
Speed: 115200 Data bits: 8 Parity: None Flow Control: None
I have turned off the mediaplayer and then I have started and only appear strange characters. Dmesg not the system nor the bootloader appears.
I tried different bauds. But nothing.
I have also tried to use the UART1 has and turn the wires, check the cables but not touching.
I tried to connect it directly to the DB9 port without passing through the converter. But exactly the same problem occurs.
Any help on how I can display the data sent from the port UART correctly.
