UART Configuration - undefined reference if Processor expert is executed

[frankmuenzner7421]

I, I try to add uart funktionality to my code.

For this i looked what is be done in uart_pal_EchoS32k144

Then i used processorexpert to add the same uart (lpuart 1)

but i get the errormessagefrom Processor Expert

./Sources/main.o: In function `main':
C:\Users\FablabRonny\Documents\S32K1444Projects\iseled_freemaster_s32k144\iseled_freemaster_s32k144\Debug_FLASH/../Sources/main.c:274: undefined reference to `UART_Init'
C:\Users\FablabRonny\Documents\S32K1444Projects\iseled_freemaster_s32k144\iseled_freemaster_s32k144\Debug_FLASH/../Sources/main.c:278: undefined reference to `UART_SendData'

Anybody has some recommendation how to solve it, i did'nt find a solution....

I try it really hard, but find no solution

Hi @frankmuenzner7421,

You wrote that you were referring to the uart_pal_echo_S32k144 example.

But you don't use the PAL drivers in your project.

Your project:

Example:

Please refer to the lpuart_echo_s32k144 example instead and use these functions:

LPUART_DRV_Init(INST_LPUART1, &lpuart1_State, &lpuart1_InitConfig0);

LPUART_DRV_SendDataBlocking(INST_LPUART1, (uint8_t *)welcomeMsg, strlen(welcomeMsg), TIMEOUT);

You can access the documentation of the driver by right-clicking on the LPUART component.
