Hi, first of all i hope, that my question lies within the realm of validity of this mailing-list. It's also possible, that simulavr is not the problem. In this case i would appreciate tips for where to pose this question.
I just compiled the latest simulavr from the git-repository, to test some simple programs written in assembler. Simulavr in combination with ddd and gdb did a great job for the most programs. But one simple program behaves incorrectly. Here's the code of the assembler file: #include <avr/io.h> #define test 16 .section .data .equ k,255 output: .asciz "Hallo Welt" .section .bss .comm buffer, 20 .section .text .global main delay: ld test, X nop ret main: ldi XL, 0x60 ldi XH, 0x00 main_loop: rcall delay rjmp main_loop After i loaded the binary file and connected gdb with simulavr (gdb) x/20xb &output yields an empty memory within the defined range. So the question i pose is, whether the error (that the string is not located in the SRAM) is produced by simulavr or avr-gcc? Besides that, maybe sb. who is reading my post can answer me this question, too: How can i bring the address of the string labeled by output in the pointer register X? The possibility i have chosen above isn't very elegant... (lo8(..) and hi8() both give errors) Kind regards and thanks for your effort Johannes D. _______________________________________________ Simulavr-devel mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/simulavr-devel
