Title: Eddy 2.5 problem with debug console
Post by: kaml on April 11, 2014, 07:41:21 AM
Hello

How to enable console input in Eddy 2.5 board?
Uncommenting
Code: [Select]
ttyS0::respawn:/sbin/getty -L ttyS0 115200 vt100
in /etc/inittab only shows "Welcome to the Eddy development environment." in console, but i cannot login.
DBGU uart works  great in u-boot but on linux doesn't.

Regards
kaml

Hello kaml,
you did not describe completely your system set-up.

We assume you are using an Eddy-CPU v2.5 plugged on a Eddy-DK v2.1 development board.
There are no command to enable the console port of Eddy-DK 2.1 with Eddy-CPU v2.5.
Simply plug the DE-09 connector to the console port, then use it.
By the way, users cannot log in from the debugging port.
Use telnet to connect to Eddy and login.

Cheers,
 Horsa

Hello

Thanks for reply.
I use  Eddy-DK v2.1 development board.
I just want to use debug serial(UART) console.
I found that in kernel the RX interrupt from debug serial port was disabled. After enabled it everything works.
