RFD 900x SiK radio corrupted package when uploading firmware locally

Hello I’m trying to upload firmware to RFD 900x using mission planner. I conected the rfd9000x to telem1 port on pixhawk orange cube+. When I’m trying to upload firmware, it gives an error saying: corrupted packet. please power cycle and try again..
Here’s how the config looks:

Idk if its useful but heres the port info

I also tried to upload by loading RFDSiK V3.57 rfd900x.bin that I downloaded from https://files.rfdesign.com.au/firmware/

When I upload firmware, the radio only shows solid red light.

What am I doing wrong?
