FreeMaster-LPUART implementation for Non-SDKs

KARTHKSARODE — Tue, 29 Mar 2022 11:42:00 GMT

As stated in the subject , I wanted to explore freemaster using LPUART for S32K144

I couldn't find much resource for Non-SDK implementation , but I wanted to implement in Non-SDKs

First I added FreeMaster Serial Communication files to the project
Configured LPUART1 of 9600 baud, 1 stop bit, 8 bit format, no parity
Configured Pins for the same
Enabled the interrupt for LPUART1
Called FMSTR_Init() function once , called FMSTR_Poll() function in infinite for loop
Called FMSTR_Isr() inside LPUART1_RxTx_IRQHandler()

Project is getting complied and running successfully

Once I try to connect using FreeMaster , it is throwing error as No Board detected on any specified UART Communication Board ( I have tried to connect after reset )

Please find the attached project

Please help me to rectify this issue
