I am new to LEDE/OpenWRT and me and my colegues found it interesting for use in our remote service routers. (Open source, custimizable, more-less HW/wendor independent...)
To start somehow, I took old Routerboard RB133, which is more less useless in todays standards (slow CPU, only 100MBit ports...) to use it as test device to look thru basic options. Nobody cares if it gets bricked, burned, tossed out of thew window in anger, etc in the proces. Later we will switch to something more powerfull.
I started going thru this manual:
and while it is missing some info i also looked thru here:
and build manual and serching some more in OpenWRT wiki...
And I got stuck.
As I understand I have RB with clean NAND (so RouterOS and Licences are no more) and bootloader works fine, takes DHCP, and boots images downloaded using TFTP. When I load any elf file for ADM5120 I can find in downloads of LEDE or OpenWRT, or even what I have built myself, I get into kernel panic with init missing or reboot loop with I guess similar issue showing for just split seccond before reboot.
Only difference is, if I try to load intramfs elf file from my built binaries. This ends with kernel too big even before trying to boot it.
Does anybody know, please, how to resolve this and advance to at least bit working system?
