Hi,

I have download unified_bootloader_demo_V2.1 file and use the unified_bootloader_demo_v2.1\S32K1xx\S32K116_LIN demo. Also I download ECUBus_Master.

Hardware use PLIN and IC is S32K116.

1.Download bootloader file to S32K116,

2.Open ECUBus, and Import ECUBUS_LIN_uds.json.

Now I have an problem: How to set Send NAD and Receive NAD, ST Min, P2 .etc sttings?

I set the send NAD x55 and Receive NAD set 0X35 for testing.

3.Select the flash_driver.bin and S32K116_LIN_APP_Demo.bin Then Press start

But not sucessed, sometime show wrong {"msg":"No response","index":5}

I don't know the opertation whether correct or not?

Hi, @Sitaijun1107

Have some information to you:

1. The ECU BUS only support PCAN tool. NXP only test on PCAN-USB Pro.

2. The configuration of ECU BUS, you can reference the ECU-BUS _User guide link: https://community.nxp.com/t5/S32K-Knowledge-Base/Unified-bootloader-Demo/ta-p/1423099

Hi, @Sitaijun1107

If you have not the PEAK tool and cannot used the ECU BUS for test. I think you can :

1. Develop a GUI/script via ISO17987-2 and reference the UDS process as NXP provided

2. Just for test, you can used your hardware send the LIN TP message. The message should be integrated LIN TP(ISO17987-2)

Hi, @Sitaijun1107

We just test on PCAN-USB Pro. So, I'm not sure the DLL(provide by PEAK) is the same or not. Suggestion you:

1.Check ECU BUS can open the tool or not. You can use another LIN channel monitor the ECU-BUS LIN channel, then check the ECU-BUS can send UDS message or not

Thanks, ECU Bus can select LIN channel. When use ECU BUS send data, first must set the send NAD value and receive NAD value, so the value should be ? can you help test on S32K116?

Hi, @Sitaijun1107

Yes, the NAD is needed. If you have any questions about NAD, you can reference ISO spec.
