RouterBOOT booter 2.12

RouterBoard 112

CPU frequency: 175 MHz
  Memory size:  16 MB

Press any key within 2 seconds to enter setup..
loading kernel from nand... OK
setting up elf image... OK
jumping to kernel code
Starting...
/etc/rc.d/rc.sysinit: 21: cannot create /var/run/utmp: Cannot allocate memory
System halted.

Maybe because I have a wireless keyboard?

Try to connect RB112 to other computer, check that you have disabled Hardware flow control.
Let us know about the results.

Yes, the problem was in the Hardware flow control (manual don´t say anything about that), I see in another post later. :smiley:
I reinstall ROS 2.5 whit netinstall again and problem solved. Thank you and sorry.
