LIN unified Bootloader using ECU Bus

Asharm11 — Thu, 17 Aug 2023 07:32:04 GMT

I had downloaded the unified_bootloader_demo_v2.1 which contains demo applications of bootloader.

I want to use LIN S32K142 bootloader, but the demo project does not contain the project for LIN S32K142, so I converted the LIN S32K144 project to LIN S32K142. On flashing the bootloader project on the NXP S32K142 100 pin board, the LED pins toggle but we get the following error on ECU bus tool.

What should be done to resolve this?

Hi, @Asharm11

From your picture, I can't see the download process. If the ECU-BUS un-import process file(JASON), you can reference the ECU-BUS user guide.

Hi, @nxf10035

I am sharing you the jSON file and I am attaching the screenshot of the download groups. The .bin file we converted from s32k144 to s32k142 so the file name is same but it is according to s32k142. still we are getting the same error.

Hello nxf10035,
I also used s32k144-Q100 but still facing the same issue saying

"{The value of the parameter is invalid in the current context.","index":1}"

{"Lin read error,0x58","index":1}

I am attaching both the jSON files that is used on s32k144 and s32k142-Q100

and no changes were made to demo example while using s32k144-Q100

it would be appreciated if you can look at the both the files and tell me where i am going wrong

Hello nxf10035,

I found that VBAT pin was loose so fixed it and after fixing it ,read error is removed but I am getting this error "The specified Scheduler is empty or does not exist.","index":1", I am sharing the error snapshots as well as settings that i have done on ECU bus Tool, I'd appreciate your response on it

thank you

Hi, @Asharm11

From your picture, I see that you only select download file process. Please note, the step as following:

1. Import process(JSON)

2. Connect hardware and config LIN node information

3. Select address of ECU BUS

For how to use the ECU-BUS, you can reference the user guide of ECU_BUS.

Suggestion you can open PLIN view and check the log of LIN BUS. It's better to upload the log when you met problems.

Hello @nxf10035

I followed what you said and i have been referring the ECU bus User guide there is nothing for how to use UDS on LIN and the error remains intact

so can we have a meeting regarding this issue

I am sharing the PLIN view Image as well as current error's image

Hello, @Asharm11

From your picture, it seems the TX LIN ID un-correct. The ECU-BUS TX LIN ID should 0x3C and RX LIN ID is 0x3D.

Hello @nxf10035

I changed the TX and RX ids to 3C and 3D respectively but I am getting the same result

I am attaching the snapshot for ECU bus tool setting and LIN tp settings

thank you

Hi, @Asharm11

The log captured by PLIN-View Pro. The test step:

1. Open ECU-BUS and connect PCAN(LIN)

2. Open PLIN-View Pro and capture the LIN log

3. Click Start of ECU-BUS

Please note: before test should connect LIN BUS including GND, VBAT and LIN. If you test failed, please upload the LIN log captured by PLIN-View Pro.

Hi, @Asharm11

From your LIN log the ECU-BUS working normally. The UDS message has been sent to LIN BUS. Suggestion you check LIN configuration of ECU side:

1. Baud Rate

2. I/O as LIN feature

3. Debug ECU side received LIN messages or not

4. Hardware connect
