Custom upload_command {$SOURCE} bin instead of elf

ptiza_v_nebe · October 8, 2021, 6:55am

Hello,
by trying to set
upload_command = openocd -d2 -s $PROJECT_PACKAGES_DIR/tool-openocd/scripts -f board/st_nucleo_h743zi.cfg -c "hla_serial 003700373438510934313939" -c "program {$SOURCE} verify reset; shutdown;"

$SOURCE resolves to firmware.bin instead of firmware.elf

In platform-ststm32/builder/main.py $SOURCE is resolved as elf

openocd_args.extend([
    "-c", "program {$SOURCE} %s verify reset; shutdown;" %
    board.get("upload.offset_address", "")
])

With regards,
Ivan

Its looking like the env variable is different:
the right one with elf ending is $PROG_PATH

Use Add support for multiple ST-Link adapters · Issue #564 · platformio/platform-ststm32 · GitHub instead of a custom upload command. It is much more flexible.

The platform builder scripts decide this.

          AlwaysBuild(env.Alias("upload", upload_source, upload_actions))

with upload_source by default

          upload_source = target_firm

          target_elf = env.BuildProgram()
          target_firm = env.ElfToBin(join("$BUILD_DIR", "${PROGNAME}"), target_elf)
          env.Depends(target_firm, "checkprogsize")

being the .bin file.

In the OpenOCD path, the variable is repointed to the ELF file when no offset address is used.

          if not board.get("upload").get("offset_address"):
              upload_source = target_elf

and thus for regular OpenOCD uploads (no custom upload_command), it uploads the ELF, but in the “custom upload method” path, upload_source remains pointed at the BIN file.
