S32K344 BOOTLOADER question

CHASEN1 — Fri, 09 Jan 2026 02:44:02 GMT

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.

Lukas
