Hi Stefan,

Try making your file name "test_uart" shorter. Objtool v0.05 doesn't handle
long file names, hence the "ERROR: Unable to load .ELF file." error message.

(I also struggled with this for many hours. Changing the file name to 8.3
format eventually solved the problem.)

Hope this helps.

Can one sahde some light in this error messages? I have got this UART
sample code from http://www.mysunrise.ch/users/pfleury/ it it does not
compile. Hence I struggling with the AVR makefiles I was not able to fix
it. Any ideas what is going wrong?
