Hi, PJE
Thanks for the quick reply.
I think that i have development console board plugged the right way
because it worked before it's according to the small white dots!
I'm using the null cable that came with the development board, i have
the baudrate to 115200 8N1! To test the usb serial converter i used
another com port from the board ttyAM1 and i can communicate both sides.
I can access the console using a usb keyboard. And i also tried it on
another computer!
I don't know if it is possible that is a initialization file? That is
only allowing the ttyAM0 to send and not receive? Or something burned
on the development board?
