contiki-ipsec's Introduction

The Contiki Operating System

Build Status

Contiki is an open source operating system that runs on tiny low-power microcontrollers and makes it possible to develop applications that make efficient use of the hardware while providing standardized low-power wireless communication for a range of hardware platforms.

Contiki is used in numerous commercial and non-commercial systems, such as city sound monitoring, street lights, networked electrical power meters, industrial monitoring, radiation monitoring, construction site monitoring, alarm systems, remote house monitoring, and so on.

For more information, see the Contiki website:

contiki-ipsec's Issues

error "Reading outside memory: 0xfa8b6"

I am trying to test some methods inside the IPsec and IKEv.2 protocol, using Contiki OS as implemented by the Cooja simulation environment.

I use Ubuntu 14.04 LTS 32-bit

gcc (Ubuntu 4.8.4-2ubuntu1~14.04) 4.8.4
Copyright (C) 2013 Free Software Foundation, Inc.

msp430-gcc (GCC) 4.7.2 20120920 (mspgcc dev 20120911)
Copyright (C) 2012 Free Software Foundation, Inc.

I using Contiki-IPsec 2.7 OS, also Iโ€™m using Wismote in Cooja simulation

but every time I try to run the example "IPsec", it always gives me the same error

I'm very new in Contiki, if you can give me a small hint how I do it or any idea to overcome this issue is highly appreciated.
Thanking you in advanced.
