It happens automatically under the hood, so you don't need to worry about
it.
The make command erases, and overwrites for you.
If you do 'make telosb install ~~', you can see in your console
-----------------------
mkdir -p build/telosb
compiling Blink to a telosb binary
ncc -o build/telosb/main.exe -O -Wall -Wshadow -DDEF_TOS_AM_GROUP=0x7d

writing TOS image
cp build/telosb/main.ihex build/telosb/main.ihex.out
installing telosb bootloader using bsl
tos-bsl --telosb -c /dev/ttyUSB1 -r -e -I -p

....
-----------------------
The 'tos-bsl -e' part is the erasing part......
