New to flocklab

[Vishal Rathod]

Hello,

I am a new one to flocklab.

I was trying to run for checking er-rest-server communicate with border router. 

I had node 1 as a border router and node 2, 4, 8, 15 and 33 as  a er-rest-server nodes. I ran it for 60 minutes to see server nodes communicated with border-router as expected.  Here, I attach a xml file of my test.

I dont know how to connect border router but I tried with following command but it shows me error.

sudo ./border-router.sky -a whymper.ee.ethz.ch -p 50101 aaaa::1/64 

I already added images of border router and er-rest-server to flocklab test images. 

When I started my test it reply me with following error:

Your test has been prepared and is going to start as planned, but consider the following warnings:

         * Test-start script on observer ID 33 failed with error code EPERM and error message 28/07/2016 09:07:59 UTC - flocklab_starttest.py - ERRO - Error 5 when programming target image: Programming...

it is same for all the nodes except border router. Here, I attach a screenshot of all.

Please help me to solve this issue.

Waiting for your positive reply.

Thanks & Regards,

Vishal Rathod.

Hi Vishal

Your program image looks a bit strange. It seems as if your .text segment starts at address 0x3100. On the Tmote sky node, this address points to RAM, not to flash memory (which starts at 0x4000). Did you try to program a node on your desk with this image?

"
readelf -l 15325.Tmote.Contiki.exe

Elf file type is EXEC (Executable file)
Entry point 0x3100
There are 4 program headers, starting at offset 52

Thanks sir.

I have one question that in what format I should upload the image. (sky or any other).

I uploaded 15324 as a sky mote (border router) and 15325 as a zolerita mote (er-rest-server). 

Am I right or wrong? 

Regards,

Vishal

You find a list of available nodes in the testbed status list at https://www.flocklab.ethz.ch/user/testbedstatus.php
Currently, FlockLab does not have any "zolerita mote" nodes.

FlockLab accepts the ELF file format (see https://www.flocklab.ethz.ch/wiki/wiki/Public/Man/Tutorials/Tutorial2).
