Hello,

i use the carambola2-development board and i really need to free the UART completly.
i read several posts at this board about that topic, however, i' still having trouble with the UART.

Can someone give me a detailed ToDo-List to free up the UART completely.
Thank you so much guys.

Best regards,
Marc

I need the UART for an other application.
My plan is to communicate with a Pololu SerialToServo-IF, which needs specific pre-defined uart settings. But everything i tried yet doesn´t work.

I commented out '#ttyATH0::askfirst:/bin/ash --login' in "/etc/inittab" and rebooted the system but nothing works. I'm pretty unsure what i have to do with an gpio port described
in viewtopic.php?f=5&t=557 .

I'm thinking about to cut off the JT1 and JT2 jumpers (see schematics). However, i'm also not sure if this is a "good" solution?
I would be very glad if someone can give me hints and explanations, or better, a detailed step-by-step rule about this issue.

Thank you very much! I'm indeed unexpierienced with stuff like this.

The thing is in my '/etc/config/system'-file is no option 'kconloglevel' " to '1'.
Should i add this option? Under which section?

My '/etc/config/system' locks like:

config system
option hostname 'carambola2'
option timezone 'UTC'

config timeserver 'ntp'
list server '0.openwrt.pool.ntp.org'
list server '1.openwrt.pool.ntp.org'
list server '2.openwrt.pool.ntp.org'
list server '3.openwrt.pool.ntp.org'
option enable_server '0'

config led
option sysfs 'carambola2:green:wlan'
option name 'wlan'
option trigger 'phy0radio'
option default '0'

config led
option default '0'
option name 'eth0'
option sysfs 'carambola2:orange:eth0'
option trigger 'netdev'
option mode 'link tx rx'
option dev 'eth0'

config led
option default '0'
option name 'eth1'
option sysfs 'carambola2:orange:eth1'
option trigger 'netdev'
option mode 'link tx rx'
option dev 'eth1'

I recommend more flexible and clear way than the serial console ATH0 , to connect ft232 on usb port.

Meanwhile ft2232 gives you 2 UART:
