S32K342 CAN bootloader sample code implement problem

HarrySu — Wed, 14 Jun 2023 02:49:22 GMT

Sorry, I have deleted that comment.

I am working on S32K342 CAN bootloader，I have refered the sample code S32K344_CAN_Bootloader_RTD2d0 in

https://community.nxp.com/t5/S32K-Knowledge-Base/Unified-bootloader-Demo/ta-p/1423099

, but I got the complier error below, Mcal.h didn't exist in my project, How can this problem be resolved? My IDE is RTD v2.0.3. Thanks!

Hi,

It's might be compatibility problem of RTD2.0 with RTD2.0.3. Suggestion you can

1. create another project over RTD2.0.3

2. Configure peripherals reference bootloader project

3. Copy all bootloader code including link file to new project without RTD and generate code

4. Compare two projects and new project code should the same with old project

5. C40_IP.c should follow old project

Hello nxf10035,

Many thanks for your advice and guidance. It has given me a good direction.

Since I am still a beginner in the field of Bootloaders, I would like to confirm something with you.

Q1. The difference between the sample codes 'project _S32K344_APP_Demo_RTD2d0' and 'project _S32K344_CAN_Bootloader_RTD2d0,' is that the APP code serves as the object to be programmed via CAN, while the Bootloader code is the main code for the MCU, which needs to be programmed using the regular programming method. Am I understanding this correctly?"

Q2. In my own Application code do I need to include the 'APP_bootloader_exchange_info' file from the sample code's App src directory? This allows the MCU to update the firmware via CAN while it is running?

Best Regards,

Harry

Hi, Harry,

Answer as following:

Tomlin: Yes, most of time the APP programed by bootloader.

Tomlin: No, the APP_bootloader_exchange_info is used to exchange information between APP with bootloader when needed to update APP. APP should integrate UDS stack. Suggestion you can reference OEM spec.

Hello Tomlin @nxf10035 ,

Thanks for previous advice, I have already build successfully on S32K342 MCU using S32K344 CAN bootloader sample code, FW could be programmed into MCU too.

But I encounter another problem now. I have connected PEAK CAN donggle to GUI ECUBus.

I import the ECUBUS_344CAN_uds.json to PCAN UDS schedule from sample file: S32K3xx\S32K344_CAN\

When I click "start" on GUI, there is an error below show : Write from 0xb to 0x16 with RA 0x0,result:undefined

How can i solve this problem? Thanks!

Best Regards,

Harry

Hi, @HarrySu ,

Did you config the CAN info as following?

Re: S32K342 CAN bootloader sample code implement problem

HarrySu — Tue, 27 Jun 2023 07:56:51 GMT

Hello Tom @nxf10035 ,

Thanks for your reply, my CAN config setting is below, I followed the PDF:ECU-Bus User Guide page4 setting.

About config setting on S32K342, I have an one different setting from S32K344 CAN boot loader.
In below picture, Number Of MB :14, 14 is the maximum value that I can set in S32K342.
But S32K344 set Number Of MB :16, will it cause any error on CAN communication?

Best Regards,

Harry

Hi, @HarrySu

We just test on PCAN-USB Pro. What's your hardware type? I think you can send UDS message(0x02 0x10 0x03) to verify the hardware and bootloader working normally or not in GUI.

Hello Tom @nxf10035 ,

This is my PEAK CAN Pro HW type:

https://www.microport.com.tw/prod/CAN-Bus-%E6%8E%A7%E5%88%B6%E5%99%A8%E5%8D%80%E5%9F%9F%E7%B6%B2%E8%B7%AF/USB-to-CAN/PCAN-USB%20Pro%20FD.html

About the UDS Message,

Did you mean use PCAN view directly transmit id:0x784 payload:0x02 0x10 0x03? ( PCAN setting show below)

MCU didn't response anything.

Harry

nxf10035 — Tue, 27 Jun 2023 08:34:07 GMT

Hi, @HarrySu

Looks like the hardware is the same. Yes, PCAN view send the UDS message. If you choose CANFD, please select nominal bit rate and data bit rate are 500K.

HarrySu — Tue, 27 Jun 2023 08:41:23 GMT

Hello Tom @nxf10035 ,

What is the number of CAN ID?, could you please show the PCAN view message window?

I also want to know what the message will MCU bootloader response, Thanks a lot!

Best Regards,

Harry

nxf10035 — Tue, 27 Jun 2023 08:49:44 GMT

Hi, @HarrySu

The PCAN View send: ID(0x784) data: 0x02 0x10 0x03. Bootloader response: ID(0x7F0) data: 0x02 0x50 0x03 Please note, the IDs are default IDs, if you are modified. Theses CAN IDs will be changed.

Hello Tom @nxf10035 ,

I have checked the MCU program block in bootloader Initial stage

BOOTLOADER_MAIN_Init -> Boot_PowerONClearALLFlag->HardFault_Handler

Is it possible that I have not configured the Boot power settings properly, as I have been following the S32K344 Sample code for configuration? Thanks!

Harry

Hello Tom @nxf10035 ,

I think the problem may be that I didn't include cpu.h and port.h in the includes.h previously,

but now that I have added them, it says that cpu.h and port.h cannot be found. How can I resolve this issue? Thanks!

Best Regards,

Harry

nxf10035 — Wed, 28 Jun 2023 06:13:44 GMT

Hi, @HarrySu

The CPU.h and port.h is used other platform. For S32K342, you should follow S32K3x2 bootloader configuration and linkfile. S32K3x4 and S32K3x2 have some different.

Hello Tom @nxf10035 ,

Do you mean the Linker file of S32K342 should overwire by Linker file of S32K3X2 series MCU sample code? Thanks!

Hi, @HarrySu

S32K322 and S32K342 is same P-Flash size, TCM size etc. Unfortunately, we just have the sample code for S32K312. The P-Flash size is the same with S32K42. DTCM and ITCM size only half of S32K342/S32K322. Detail information you can reference attachment(excel) in RM. Suggestion you reference the bootloader code and link file of S32K312. You can set the same segments in link file. DTCM and ITCM size should follow keep default.

Hello Tom @nxf10035 ,

I followed your suggestion, config refer S32K312.

Also, I replace the S32K342 flash&ram linker file with S32K312 linker file, values of DTCM and ITCM from S32K342 are preserved to default .It can build succesfully, but the debuger shut down when programming, It says:

BusFault: An imprecise (asynchronous) data access error has occurred.
HardFault: A fault has been escalated to a hard fault.

If I didn't change linker file, it can programming successfully, but program also block in Hardfault while in boot power check function.

Did I make any mistakes in the above steps of modifying the memory?

BR,

Harry

Hi, @HarrySu

Did you compare the source code of S32K312 and S32K324? As following is the boot configuration in boot_cfg.c of S32K312.

Hello Tom @nxf10035 ,

My bootinfo is same like yours in S32K342 project, Thanks!
