Now changing to another mote like the one from Advanticsys (or the Z1 mote) would mean changing from dealing with code size issues to ram size issues, as normally the ram footprint is around 9Kb (as it is actually) and msp430f261x motes have 8Kb only. > € 0.02 >> >> --Antonio >> >> On Sun, Sep 9, 2012 at 10:01 PM, Hugo De Haas <[email protected]>wrote: >> >>> Hi Everybody, >>> >>> >>> >>> During compiling of the PppRouter from the TinyOS 2.1.2 I get the error >>> that the code size is too large for a TelosB.
