Hello, I have problem with RB 133. I tried update ROS version 3.30, but processor was more overextended, than I tried downgrade on 3.10 ROS. After downgrade RB do not work, system did not start.
RouterBOOT booter 2.7
RouterBoard 133
CPU frequency: 175 MHz
Memory size: 32 MB
Boot configuration reset, applying defaults
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.
I tried use NetInstall, but it did not find the RB, I tried start RB on LAN, but it the same:
