FY41AP OSD not displaying/updating


I have a new FY41AP-M that my boss gave to me to test (I work for an ag drone company). I was able to successfully update the AFSS firmware, but using the same process, I cannot get the OSD firmware to update. I used UART2 for it, and the software does not recognize that the hardware is plugged in. I also checked on my monitor, and it will not show any of the overlay info, just the live feed from the camera.
