    Hi Pradeep,

    You can link .text into multiple sections by using the >> operator and OR'ing the sections together using |.  Try doing something like this:

    .text :>> flasha | flashb | flashc

    You can learn more about this in the assembly language tools user guide.

    If you want complete control over which Flash sections you want to write / not write and you don't foresee a change in processor, then you can try combining 2 or more sections into one large section. However Trey's method is cleaner and easier for upgrades to other processors.

    Here is the Wiki link with the two methods listed.

    Pradeep,

    These errors mean that these sections (.econst and .switch) won't fit in the memory you have allocated them to.  You'll need to put these in a different memory section.
