DIY TX

I am working on a custom PCB to replace the ISRM on the Taranis X-Lite Pro based on the TX_SX1280_Minimal using ELRS firmware 2.5.7. and EdgeTX 2.7.1. This is an internal RF module replacement, and is not connected via the external module bay connector.

When trying to run the ELRS Lua Script, I receive, "Loading.... ?/??? ?" Additionally, the radio's settings report the Int. module as, "62 Hz 1 Err"

In radio settings/HARDWARE/Internal RF I hace set CRSF, tried both 115k and 400k Baudrate, and both Normal and Onebit Sample modes.

I am wondering, to make this work is there a special EdgeTX build or LUA script that I need that would allow me to use this ELRS project as my internal RF module? Likely something is wrong with my project, but I am at my wits end with troubleshooting for the day.
