First, the data sheet says (page 71) : - Data EEPROM memory is readable and writable and - the Flash program memory is readable during normal - operation (full VDD range). So, the Flash don't seem to be writeable under program control, which, AFAIK, prevents the use of a bootloader. Didn't you check that before posting ??? Second, There seems to be some problem with your kayboard. I only got lowercase characters from you, such as "i" where there should have been a "I"...
