I was performing some test with bootloaders on atmega1284 (testing if they can program all the available flash) and one test included printing a floating point number, the reason is in the file ftoa_engine which store some number in a table and read them using lpm. It works fine when the table is stored in a low memory address ( < 64K words) but when the table is stores in the upper
memory region the lpm instruction cannot load the data.
