osmocon on gta02

Hello. I've updated & rebuilt osmocom and now I can't use osmocon on gta02 anymore :( Previously I started it like: ./osmocon -i 13 -m romload -p /dev/ttySAC0 layer1.highram.bin power-cycle modem and it started to load firmware. However with recent version firmware is loaded even without power-cycle! When I use hello_world.highram.bin I got exactly the same output as before. But when I use layer1.highram.bin I have problems running osmoload -l /tmp/loader ping Query timed out. What went wrong and how do I fix it? best regards, Max.
