How to use DEBUG_VERBOSE to build micropython?

[eminarcissus]

Hi,

I've written a C based python module for esp32, and after I have it compiled in the firmware, it said cannot find module. I did check there's module.o in application.map, and I've checked builtinimport there's a debug arguments named MICROPY_DEBUG_VERBOSE in the code. So I added -DMICROPY_DEBUG_VERBOSE in the makefile, but it failed to compile with error
malloc.c:(.text.m_malloc_maybe+0x18): undefined reference to DEBUG_printf' build/py/malloc.o:malloc.c:(.text.m_malloc_with_finaliser+0x1f): more undefined references to DEBUG_printf' follow
Makefile:844: recipe for target 'build/application.elf' failed

So I'm wondering how to use this DEBUG VERBOSE flag?

lib/util/printf.c has a definition of DEBUG_printf if MICROPY_DEBUG_PRINTERS is 1, but there are probably other ways, I assume -DDEBUG_printf=printf or so might also do the trick, not tested though

Weird, didn’t noticed this flag, thanks very much for the help :) -- Narcissus Emi 日時: 2018年4月20日 18:25:58, stinos (notifications@github.com) が書きました::

The esp32 port doesn't use the internal (uPy-provided) printf code because it has its own printf that it needs to use. You might need to add your own implementation of DEBUG_printf, just copy that in lib/utils/printf.c

Note that you can do help('modules') at the REPL to list known built-in modules. And you must put your custom C modules in mpconfigport.h, in MICROPY_PORT_BUILTIN_MODULES

Got it working right now, that really helps, thx very much for the help :)

could you please tell me how
i've tried enabling MICROPY_DEBUG_PRINTERS to get DEBUG_printf but i always get bootloop
