Showing [hello-world.upload] Error 2 in contiki - contiki

Question

I am trying to upload hello-world in Micaz using Contiki.
I followed these steps
user#instant-contiki:~$ cd contiki/examples/hello-world
user#instant-contiki:~/contiki/examples/hello-world$ make TARGET=micaz hello-world
CC hello-world.c
LD hello-world.micaz
rm hello-world.co
user#instant-contiki:~/contiki/examples/hello-world$ make TARGET=micaz savetarget
saving Makefile.target
Finally while uploading I got the below error
user#instant-contiki:~/contiki/examples/hello-world$ make hello-world.upload
using saved target 'micaz'
avr-objcopy -O srec hello-world.micaz hello-world.srec
uisp -dprog=mib510 -dserial=/dev/ttyS0 -dpart=ATmega128 --wr_fuse_h=0xd1 --wr_fuse_e=ff --erase --upload if=hello-world.srec --verify
Error: Permission denied
-> /dev/ttyS0
make: *** [hello-world.upload] Error 1
rm hello-world.srec
I have seen many Stackoverflow questions regarding the same .
But those workaround is not solving my issues.
Am I doing anything wrong.
Please Suggest.

First of all, the problem is about permission.
Try "sudo make hello-world.upload"
And if you use Instant contiki 2.7 and it is your first time compiling with Micaz,
you may have another problem about "make: uisp: Command not found"
Then, refer following link.
