MAVSDK-Python: Raspberry Pi : from mavsdk : Illegal Instruction

Im starting off with mavsdk on my raspberry pi connected to a pixhawk via the UART.

the following is the code.

when i run it with “python3 simple_arm.py”

the terminal shows the output as “Illegal Instruction”

i think ive narrowed down the issue to from mavsdk import System

P.S : Does mavsdk python work on raspberry Pi model B+ (with arm6)?

import asyncio
from mavsdk import System

async def run():
    print("In run")
    drone =System()
    await drone.connect(system_address="udp://localhost:14550")
    print("Waiting to connect to drone.....")
    async for state in drone.core.connection_state():
        if state.is_connected:
            print("Conected to drone: %s" % state.uuid)
            break

    print("Waiting for drone to have a global position estimate...")
    async for health in drone.telemetry.health():
        if health.is_global_position_ok:
            print("Global position estimate ok")
            break    
if __name__ == "__main__":
    print("In main loop")
    loop = asyncio.get_event_loop()
    loop.run_until_complete(run())
