How to rename spiffs.bin on build

frucot · April 23, 2020, 7:58am

Working with ESP32 Wroom, i want to rename spiffs.bin file on build. I success with firmware.bin, but i can’t find any doc about this topic.

Somebody can help ?
Thanks

spiffs.bin is hardcoded.

github.com

platformio/platform-espressif32/blob/86fbfad669cc3639fcf1747b2f5452808e663d7b/builder/main.py#L215


      
          
          
#
          # Target: Build executable and linkable firmware or SPIFFS image
          #
          
          
target_elf = env.BuildProgram()
          if "nobuild" in COMMAND_LINE_TARGETS:
              target_elf = join("$BUILD_DIR", "${PROGNAME}.elf")
              if set(["uploadfs", "uploadfsota"]) & set(COMMAND_LINE_TARGETS):
                  fetch_spiffs_size(env)
                  target_firm = join("$BUILD_DIR", "spiffs.bin")
              else:
                  target_firm = join("$BUILD_DIR", "${PROGNAME}.bin")
          else:
              if set(["buildfs", "uploadfs", "uploadfsota"]) & set(COMMAND_LINE_TARGETS):
                  target_firm = env.DataToBin(
                      join("$BUILD_DIR", "spiffs"), "$PROJECTDATA_DIR")
                  AlwaysBuild(target_firm)
                  AlwaysBuild(env.Alias("buildfs", target_firm))
              else:
                  target_firm = env.ElfToBin(

So you’ll have to look into Advanced Scripting and use callbacks for

env.AddPostAction("$BUILD_DIR/spiffs.bin", callback...)

for copying the file to a new filename. If you rename the spiffs.bin, the SPIFFS upload will fail, since it looks for a spiffs.bin.

it runs. I can copy the file where i want.

The hardcoding of “spiffs.bin” is not a very good thing imho

Thanks for your usefull answer
