I'm a beginner. I'm using an atmega8L with 12MHz. when I compile the code (WINAVR) , it does not recognize the register x4 in usbdrvasm12.S
The error messages I get are,
Code: Select all
Assembling: usbdrvasm.S
avr-gcc -c -mmcu=atmega8 -I. -x assembler-with-cpp -Wa,-adhlns=usbdrvasm.lst,-gstabs usbdrvasm.S -o usbdrvasm.o

make.exe: *** [usbdrvasm.o] Error 1
The first error points to the code,
