by flashing a wrong uboot i managed to bricck my guruplug
After powering it, the red light flashes for 1 second, and then the green light is the only one burning

after reading i found that the guruplug-installer should work
so i connect the jtag to my linux pc, and the guruplug to the jtag

then ./runme.sh uboot.guruplug.bin

and i get this:

[root@smeserver guruplug-installer]# ./runme.sh uboot.guruplug.bin
 ****     Preparing environment variables file ...
 ****   Burning uboot and environment variables ... This will take few minutes ...
