[qemu-hexagon] Error mapping file: Invalid argument

[Waksmanski, Lukasz]

Hello,

 

I’m trying to run Hexagon executables in qemu-hexagon. I’m using official stable version v6.1. Here’s my rather simple program:

➜  ~ cat test.c

#include<stdio.h>

int main()

{  printf("Hello Hexagon!");

  return 0;

}

 

I’m using  Hexagon SDK 4.0.2 toolchain:

➜  ~ ~/tools/Hexagon4/tools/HEXAGON_Tools/8.4.09/Tools/bin/hexagon-clang -mv67 -o test test.c

 

Running in qemu produces error somewhere in mmap

➜  ~ qemu-hexagon ./test                                                                    

qemu-hexagon: ./test: Error mapping file: Invalid argument

 

Am I doing something naively wrong here?

 

Here’s  are the some details about the executable

➜  ~ ~/tools/Hexagon4/tools/HEXAGON_Tools/8.4.09/Tools/bin/hexagon-llvm-readelf -h ./test

Could you tell me where the problem is? Is it because I’m compiling for QuRT, and qemu uses is linux-user? Or is something else?
