Hi Guys, sorry if its a stupid question
I have edited the script.fex in the boot folder and enabled the extra uart ports on the board.
#dmesg | grep uart

however i cant appear to use them and any ttl device i plugin wil not send/recv data - is there more i need to do ?
on the original pcduino kernel you also had to
echo "3" > /sys/device/virtual/misc/gpio/mode/gpio12
to the appropriate pins however this kernel does not appear to have an equivilant ?
Thanks.
