Hello!
In the last weekend (yes, on sunday!) i tried to upgrade a RB532A (mipsle) router to 6.29.1. There weren’t any problems with the upload. After i did the reboot, the router died.
Today i managed to connect to it via rs232 and tried netinstall, but this happened:
RouterBoard 532A

Kernel panic - not syncing: Attempted to kill init!
Rebooting in 1 seconds..
I already tried resetting the configuration and formating the nand.
Any clues?
