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.
Pinout:
1 Ground
2 UART_RX0
3 UART_TX0
4 UART_RX1
5 UART_TX1
6 VDC 3.3v
Image below.
I tried to connect the port UART with connector Sitecom CN-104 v4002
sitecomlearningcentre.com/es/products/cn-104v4002/usb-to-serial-cable-0-6m/downloads
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.
I connected:
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.
