Hi George,
I do not have a solution, but I thought I'd share our findings. We are facing
the same problem on Ubuntu 11. But the identical code compiles on Debian5 and
Ubuntu 10 machines. The error we get is similar to yours, but not identical:
two source files specified (PLATFORM_NULL and

It does indeed persist, at least to
Hi,
try encryting the cipher text again. The CC2420 AES works in CTR mode,
meaning encryption and decryption are the same operation.
Moreover, if you send your packets anyway, you can use the built-in
functionality of the CC2420 chip to encrypt all outgoing packets on the fly. It

of the key-bytes, because the key is read like that (i.e., backwards) into RAM.
But this affects encryption as well as decryption and is already done by that
library. You should not need to invert anything.

the encryption process is needed. Consequently, you will have
to implement your own CTR mode, if you want to be able to decrypt your data. If
you are not familiar with CTR, Wikipedia is a good place to start.

Hi,
it means your image is too large, it will not fit on the mote.

using.
