Hi Umesh,
that's just the ordinary escaping scheme of the 0x7D sync byte. It's done
by stuffing a 0x7D into the stream and XORing the actual byte with 0x20
(0x7D xor 0x20 = 0x5D). In your case, the crc happens to have 0x7D on that
line. A search on the list will tell you more if you want.

Hi Phil,I was trying to debug the problem, I realised the problem was in my code and hence your changes work just fine. Due to a multitude of code changes I ended up reinitializing the node id's midway during simulation (this was a hack to get around the earlier bug) duh !!. Things are working

Hi everybody,I am trying to figure out how to read from the internal flash, on a tmote sky.For as much as I have understood, BlockStorage and EEPROM ( ByteEEPROM and PageEEPROM ) are both used for reading/writing/formatting the external flash.
On the other side there is the InternalFlash module,

Hi Phil,
There's a bug in the beta that prevents you from simulating more than
100 nodes. It's in tos/chips/atm128/sim/atm128hardware.h:

should be

Let me know if the message payload size gives you any problems. I uploaded
some changes this morning to reflect a 28-byte payload maximum, which should
be compatible with everyone's system.
Before, I had the payload sizes of the FlashViewer messages set to my
environment - 30 byte payloads,
Any help?
My questions are about what I should do?
If somebody says me that Telegesis ETRX1 is not
suitable for TinyOS, I have solved all my probs.
Differently, the problem could be about ISP parallel
cable or USB-to-RS232 or ...something else?

Hi Phil,Again thanks a lot. I think thats the behaviour I am observing. The minute I step beyond 100 the simulation segfaults at boot up. Will try the fix and get back to you.Thanks,Avinash

I have another question about the paper http://nesl.ee.ucla.edu/document/show/153 , figure 11a drift and temperature variation.

But from 4 to 8 hours, the temperature is constant at
