S32K312 EVB Uart Not working

[nikhilvv07]

hi,

Am Newbie in NXP S32K.

Am trying to implement UART Communication to Communicate with Terminal software in autosar mode by using Evaluation board XS32K312EVB-Q172 hardware.

i configured Uart as following 

In main.c i added 

#include "Mcal.h"
#include "Mcu.h"
#include "Port.h"
#include "Dio.h"
#include "IntCtrl_Ip.h"
#include "Lpuart_Uart_Ip.h"
#include "CDD_Uart.h"

and from main() i called Uart_Init(NULL_PTR);

but when start Debug the control moves to hardware fault loop.

is there any missing in my configuration?

Hi Robin,

Thank you for your support. i will check the same and update you.

some more questions regarding UART.

> Where can i initialize Lpuart_Uart_Ip_StateStructureType structure.

It seems it holds rx and tx buffers and other related information. But in application i did not intialized these struct variables. and it says driver doesnot provide memory for it.

So how can we initiate this struct. ?

> from where can i get received bytes?

in some other example i have seen they are setting callback event. But here i did not find any settings like that. instead i hope we can check in call back when it called by checking Lpuart_Uart_Ip_EventType.

is it correct ?

is there any way to check the receive buffer and read the receive data by bytes.? 

thanks,

Nikhil

Hi Nikhil,

Sorry, I’ve been busy lately, so I haven’t replied to you until now.
I see that you are using AUTOSAR MCAL HLD (High Level Driver). I suggest you create a new question so that my colleague in charge of MCAL software can help you.

Best Regards,
Robin

Hi Robin,

Sure i will create a new ticket.

Can u please tell me from where you have find out MCAL HLD option and how to select this option?

[Robin_Shen]

The Configuration Component that you selected belongs to AUTOSAR MCAL HLD.

For more detail, please read AN13435: SDK/MCAL to Real-Time Drivers - Application Note

HI Robin,

As per the discussion i raised new query of the same issue.

Thank you for sharing the document. 

I Hope your colleague will respond soon as possible for the query. meanwhile can you clarify following points.

Hi

I checked the project you sent me via private message and found that you forgot to enable the Peripheral Clock of LPUART0.

Best Regards,
Robin
