S32K344 BOOTLOADER question

Hello,

I downloaded unified_bootloader_demo_V2.1, programmed S32K344_CAN_bootloader_RTD2d0.elf via the debugger, then opened the ECUBus host computer. I selected the file ECUBUS_344CAN_uds.json in the DOCAN Service Table, and after connecting the PCAN, successfully programmed S32K344_FlsDrvRTD100.bin and S32K344_CAN_App_RTD200.bin. Now, I am preparing to download my own application code S32K344_VCU_v1.0.bin. In the ECUBus host computer, I still selected ECUBUS_344CAN_uds.json for the DOCAN Service Table, and chose S32K344_FlsDrvRTD100.bin and S32K344_VCU_v1.0.bin in the two DownLoadFile1 fields, but the download was unsuccessful, prompting [4240ms][sch1]{"msg":"No response","index":1}.

Is there any issue with this operation? I would appreciate your guidance.

I look forward to your help and am very grateful for it.

Hi @CHASEN1 

Does your application follow memory layout of CAN_App project? 

Anyway, please notice that Unified bootloader is unofficial example shared by an individual on the community, so it's provided AS IS with no guarantees and no support. 

Regards,

Lukas
