Lora E5 dev Board | LoraWan End Note | lpuart1 + uart2

I am using the Lora E5 dev board / WIO-E5
Software “LoRaWan EndNote”
The connection to the TTN is particularly good with the Cayenne connection.

When I want to embed with MX LPuart and Usart the code doesn’t work anymore.

How can I initialize lpuart1 and usart(2) without MX ?
