[HarrySu]

Hello NXP, @nxf10035 

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!

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?

Hi, @HarrySu 

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

Hi,

I have a question about "tbootInfo". Could you tell me what is the meaning of the different parts of the structure because I want to use "requestBackdoor" of the bootloader. I want that the bootloader waits a little time to enter to application but I have different errors. 

Thank you,

Hi, @HarrySu 

    Please compare other source code. If you found all the code are same. You can share the project to me.

Hello Tom @nxf10035 ,

Did you mean compare following source code file? Entire file were copied from S32K312 sorce code file.

Due to our company policy, I am unable to upload or send the code. I was wondering if it would be possible to schedule a meeting with you to go through my code together. I'm not sure if Tom is available for this. If we can communicate in Chinese, it would be easier for me to express. Thank you!

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!
