Hi i want to use UART0 on FirePrime evb and I’ve followed everything in homepage at "Using UART"But i was not able to recieve data from PC to board it just gets two bit and then serial port doesnt work any more
it is while i can send data from board to PC without any problem.
How can I fix this?
Please help me
Thank you for your support
hi
is there any problem in your uart wire ? connect the TX to RX ,then check whether it is ok in your PC.
yes my pc is OK
I can send and recieve data even connect to debug port
But im not able to send data to port using uart0 
after two first character it stops working some times after sending first charachter!
that is so strange，have you test it in both Ubuntu and Android ?
Ive just tried Ubuntu , and no luck
we need it to work on ubuntu
I had changed device tree files (.dtsi) in different ways and again no luck
have you disabled the blue tooth in the dts?
yes I had disabled it in rk3128-fireprime.dts file
and enabled uart0 node
For now i’ve given up fireprime evb as i dont have enough time to work on it
besides it has just one uart available while i need at least 2 uart ports
I think I would work with RK3288-Reload
Thanks for your support bro
