Thank you, it was indeed a timing problem, now I get:
brot@brotkorb:~/Downloads/AVM7530 $ ./eva_ramboot.py --offset 0x85000000 192.168.178.1 uboot-fritz7530.bin
> SETENV memsize 0x00080000
< 200 SETENV command successful
> SETENV kernel_args_tmp mtdram1=0x85000000,0x88000000
< 200 SETENV command successful
> MEDIA SDRAM
< 200 Media set to MEDIA_SDRAM
But I'm stuck on the next step now:
brot@brotkorb:~/Downloads/AVM7530 $ sudo dnsmasq --listen-address=0.0.0.0 --port=0 --enable-tftp --tftp-root=/home/brot/Downloads/AVM7530/tftp --tftp-no-blocksize --user=root --group=root
brot@brotkorb:~/Downloads/AVM7530 $ netstat -lunp | grep 69
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)

Another timing problem? How can I check if the router pulled the file? I pinged it and this works but the file transer via scp is not working.
