Error uploading firmware at px4fmu and px4io v1.3

Hello i am trying to upload the firmware from mision planner at px4fmu and px4io v1.3 and i get this error
Could someone help me?
Do i have to download an older version ?

Good day, which board you need update

What do you mean at px4io v1.3

you can try update your board with a jtag programmer

Given you are using MissionPlanner, you are probably using ArduPilott and therefore you should ask in their forums rather than the PX4 forum here.
