build MP frozon modules issue

[starter111]

I'm trying to build my own firmware using windows Cygwin. Here's the issue I got.

1. download source code: $ git clone https://github.com/micropython/micropython.git
2. make cross compiler from the root directory: looks like OK! $ make CROSS_COMPILE=i686-w64-mingw32- -C mpy-cross
3. run make from stmhal/ directory. $ make BOARD=PYBV11

but show error:
CC ../py/../extmod/uos_dupterm.c
CC ../py/../lib/embed/abort_.c
CC ../py/../lib/utils/printf.c
MPY modules/lcd160cr.py
Traceback (most recent call last):
File "modules/lcd160cr.py", line 1
SyntaxError: invalid syntax
make: *** [../py/mkrules.mk:113: build-PYBV11/frozen_mpy/lcd160cr.mpy] Error 1

I also did try take out "FROZEN_MPY_DIR ?= modules" from Makefile and it works. Builds fine, I can program the .dfu and connected to my pyboard.

Is it something wrong with my setup or how can I make frozen module works?
I'm trying to save about 30k RAM, a lot of functions I will not use. Is it possible save 30k more? How can I tell which module takes more RAM?

Just found this...
https://github.com/micropython/micropython/issues/2961

copy the original .py files to modules folder works ok now..
now need to find out where can I take out the modules like lcd160cr..which I will never use....

[dhylands]

Since the lcd files are frozen modules, they shouldn't affect your RAM usage (assuming that you don't use them). They'll take up space in flash.

To remove them, you can either remove the files from the modules directory, or when you build you can specify FROZEN_MPY_DIR to be someplace else other than modules (perhaps even an empty directory). Something like:

Code: Select all

make BOARD=PYBV11 FROZEN_MPY_DIR=my_modules_dir

[starter111]

Hi Dave, Thanks for your reply.
Got it..no wonder doesn't make difference after remove modules. So, they only take RAM space whenever import the modules.

now the question is what eats my RAM..how can I reduce RAM? I saw the minimal port readme mention if disable MicroPython compiler can reduce 20k? How can I do that on pyboard?

[pythoncoder]

To check on RAM use

Code: Select all

>>> import micropython
>>> micropython.mem_info()
stack: 484 out of 15360
GC: total: 102208, used: 9728, free: 92480
 No. of 1-blocks: 25, 2-blocks: 8, max blk sz: 498, max free sz: 5745
>>> 

You can then import modules one at a time to check on their impact:

Code: Select all

>>> import math
>>> micropython.mem_info()
stack: 484 out of 15360
GC: total: 102208, used: 9904, free: 92304
 No. of 1-blocks: 30, 2-blocks: 11, max blk sz: 498, max free sz: 5745
>>> import uasyncio
>>> micropython.mem_info()
stack: 484 out of 15360
GC: total: 102208, used: 15216, free: 86992
 No. of 1-blocks: 175, 2-blocks: 30, max blk sz: 498, max free sz: 5425
>>> 

So on this Pyboard importing math and uasyncio used 15216-9728 = 5488 bytes.

I'd look carefully at the Python code you're running before investigating special build options.

[dhylands]

Turning off the compiler would reduce flash usage, but again, if you don't use the compiler, then it shouldn't be consuming any RAM.

The STM32F405 has 192K of RAM.
64K of that is currently reserved for the filesystem (so that it can rewrite a 64K flash block).
Of the remaining 128K, 102272 bytes are used for the heap, which means that there is 28800 bytes of RAM used by micropython. 16K of that is reserved for the stack. .bss and .data account for about 10K. The balance is overhead for the heap.

Probably one of the larger items from the 10K are the USB buffers, but you'd have to scour through the map file and see what can be freed up.

If you could turn off the filesystem you could use the 64K, but it's not contiguous with RAM, so it can't just be added to the heap. You could probably mess with the linker map and move .bss into the 64K block.

[starter111]

Thanks for both.
basically micropython doesn't take much RAM...
in this case, I need think of something else... maybe change to STM32F7 or other approach...

[DGW]

Good afternoon.
At compilation I receive an error (Error 2)! What am I doing wrong?

[dhylands]

Without seeing your build logs which show the exact error, its virtually impossible for somebody to guess what your problem might be.
