ulp code as an esp-idf project component not compiling

I have adapted the ulp_i2c_bitbang code from the "esp-iot-solution" github directory. It compiles and runs when all the files are in the "main" directory of the project. When I create a separate component directory for the ulp associated files the project does not compile. The assembly (*.S) files are compiled and *.lst files are generated, the ulp_mag.h file is not generated. I get the following errors:

I can not find any circular dependency in my *.cpp or *.h files.
I suspect that I have a problem with the makefiles. I moved the "ulp makefile" into the component directory. Here is the makefile:
Code: [Select all] [Expand/Collapse]
  1. #
  2. # ULP support additions to component makefile.
  3. #
  4. # 1. ULP_APP_NAME must be unique (if multiple components use ULP)
  5. #    Default value, override if necessary:
  6. ULP_APP_NAME ?= ulp_$(COMPONENT_NAME)
  7. #
  8. # 2. Specify all assembly source files here.
  9. #    Files should be placed into a separate directory (in this case, ulp/),
  10. #    which should not be added to COMPONENT_SRCDIRS.
  11. ULP_S_SOURCES = $(addprefix $(COMPONENT_PATH)/ulp/, \
  12.     i2c_dev.S \
  13.     i2c.S \
  14.     stack.S \
  15.     )
  16. #
  17. # 3. List all the component object files which include automatically
  18. #    generated ULP export file, $(ULP_APP_NAME).h:
  19. #ULP_EXP_DEP_OBJECTS := main.o
  20. #ULP_EXP_DEP_OBJECTS := mag.o main.o
  21. ULP_EXP_DEP_OBJECTS := mag.o
  22. #ULP_EXP_DEP_OBJECTS := mag.o main.o ulp3.o  
  23. #
  24. # 4. Include build rules for ULP program
  25. include $(IDF_PATH)/components/ulp/component_ulp_common.mk
  26. #
  27. # Link object files and generate map file
  28. $(ULP_ELF): $(ULP_OBJECTS) $(ULP_LD_SCRIPT)
  29.     $(summary) ULP_LD $(patsubst $(PWD)/%,%,$(CURDIR))/$@
  30.     $(ULP_LD) -o $@ -A elf32-esp32ulp -Map=$(ULP_MAP) -T $(ULP_LD_SCRIPT) $(ULP_OBJECTS)
  31. #
  32. # End of ULP support additions to component makefile.
  33. #
  34. #COMPONENT_ADD_INCLUDEDIRS := .
  35. #COMPONENT_SRCDIRS := .

The directory structure is:
ulp3
.....main: main.cpp, component.mk
.....components
..........mag: component.mk, mag.cpp, mag.h
...............ulp: i2c.S, i2c_dev.S, stack.S

This is on a Windows 10 system with esp-idf 3.2

Any help appreciated

I have not experimented with any directory structure other than that explicitly supported by the esp idf, but I have a project using ULP code in which a directory appears in main called ULP. The .S files in that directory both assemble and are linked into the program of which the .cpp file is in main.

Code: Select all

build
main
\ something.cpp
     CMakeLists.txt
     component.mk
     etc.
     ULP
       \ something.S
sdkconfig
etc.
This works. Good luck.

This works for me as well, but not when I move the ulp files to a component subdirectory. I'm trying to create a component so that the user is insulated from the ulp code.
Thanks

Comparing your file to https://github.com/espressif/esp-idf/bl ... mponent.mk, it seems that lines 28-30 are not present in the template. Can you please try removing these?

Thanks for the suggestion, but the results are still the same.
