Hello everybody, When I tried to compile my tinyos code where there is some machine code. I have the following error : BintM.nc:394: error: can't find a register in class 'BASE_POINTER_REGS' while reloading 'asm'
Where the problem come from the fact there is some asm volatile asm volatile ( " push r2 \n" " push r3 \n" " push r26 \n" " push r27 \n" " push r30 \n" " push r31 \n" "1: \n" " ld r2, Z+ \n" " ld r3, X \n" " lsr %0 \n" " sbc r3, r2 \n" " rol %0 \n" " st X+, r3 \n" " dec %1 \n" " brne 1b \n" " pop r31 \n" " pop r30 \n" " pop r27 \n" " pop r26 \n" " pop r3 \n" " pop r2 \n" :"+r"(borrow), "+r"(nwords) :"z"(a), "x"(b) :"r2", "r3" ); I search the web for the bug and I found it http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31786 This bug has been solve since the version 4.4 of avr-gcc The problem is I have the version 4.1.2 /usr/lib/gcc/avr/4.1.2 And I am using ubuntu and I install the debian package for tinyos. How can I update the gcc avr to the version 4.4 ? Thanks a lot :) Best Loic
