Hello!

My hardware:

- module DART-MX6 Rev 1.2 DART-MX6 CPU: Freescale iMX6 | System on Module - Variscite

- board DART-DT6CustomBoard V1.1 VAR-DT6CustomBoard - Variscite

My sofware:

- Yocto Jethro

- linux-4.1.15

please see attached file

- busybox-1.25.0

- linux command line

~ # cat /proc/cmdline                                                          
noinitrd console=ttymxc0,115200 root=/dev/ram0 ip=off rdinit=/sbin/initux command line

- file /etc/inittab

~ # cat /etc/inittab                                                           
::sysinit:/etc/init.d/rcS                                                      
::respawn:/sbin/getty -L /dev/ttymxc0 115200                                   
::restart:/sbin/init                                                           
::ctrlaltdel:/bin/umount -a -r

 

I have very strange problem - serial port work only if ethernet configured and active.

How can I solve this problem?

Thank you and excuse my bad english.

Hi Kirill

there are no known conflicts between serial ports and ethernet

and one can try to debug it using AN4553 Using Open Source

Debugging Tools for Linux on i.MX Processors

Best regards
