For Lin the irq handler is not hitting after the current state is set as breakfield when the sendframe function is called after that the irq need to hit but it is not hitting,
it is not updating to LPUART_LIN_IP_NODE_STATE_SEND_SYNC because irq is not hitting the irq we are using is Lpuart_Lin_Ip_IRQHandler(1U); why it is not hitting can you provide more information on this ...

Hi,

what is a device/board and RTD version you are using? Is interrupt properly enabled for LPUART used?
Anyway the RTD demo example works properly, you can refer to it.
For LIN transceiver is it active and is there LIN master termination installed?

BR, Petr
