DMCP_SDK Hello World

Post by Michael » Thu Jun 14, 2018 6:38 pm

Here is a 'Hello World!' demo application
https://github.com/swissmicros/DMCP_SDK

A simple RPN calculator demo application will follow.

What if you add -std=c99 or -std=c11?

But what is a policy of DM42 SDK - are we C99 compliant?

With following options:

Code: Select all

CFLAGS += -std=c99
CFLAGS += -pedantic-errors

Code: Select all

Re: DMCP_SDK Hello World

Did someone build this "Hello World" (and/or the complete package) in an Windows (7) environment,
and could give some advice?
What would be a useful working environment?

Many thanks in advance!

Hi Thomas,
frankly speaking, SW development for embedded systems with GNU tools is much easier under Linux.
But sometimes there is no other choice, Windows only. I would suggest to use MinGW.

I just tested the build in Windows 10 MinGW environment:

Code: Select all

...
arm-none-eabi-objcopy --only-section   .qspi -O ihex    build/TESTPGM.elf  build/TESTPGM_qspi.hex
arm-none-eabi-objcopy --only-section   .qspi -O binary  build/TESTPGM.elf  build/TESTPGM_qspi.bin
bin/check_qspi_crc TESTPGM src/qspi_crc.h || ( make clean && false )
bin/add_pgm_chsum build/TESTPGM_flash.bin build/TESTPGM.pgm
FIND: Parameter format not correct
SHA1: 8d668604ee1fd16b96d5210e01469538bb2fb4d9*
arm-none-eabi-size build/TESTPGM.elf
   text    data     bss     dec     hex filename
    752    1088      64    1904     770 build/TESTPGM.elf

C:\Users\...\GITProjects\DMCP_SDK>

There is something wrong with hash calculations: FIND: Parameter format not correct, perhaps binary tools (add_pgm_chsum etc.) should be re-compiled for Windows too.

1) Install MinGW (http://mingw.org/)
There is a GUI installer tool for windows: https://sourceforge.net/projects/mingw/files/Installer/

2) Install GNU Arm Embedded Toolchain for Windows https://developer.arm.com/open-source/g ... /downloads

3) Create BAT file to set path in to console environment. I have setenv.bat:

Code: Select all

set PATH=%PATH%;C:\MinGW\msys\1.0\bin;C:\Program Files (x86)\GNU Tools ARM Embedded\7 2017-q4-major\bin
You can also add path in to Windows system environment variables, if you want. I do prefer to keep environment local for every project.

4) Clone DMCP_SDK GIT repository and copy setenv.bat file in to the project's folder

5) Open windows terminal, run setenv.bat and type make -v

Code: Select all

C:\Users\...\GITProjects\DMCP_SDK>make -v

If you don't have make you have to install it separately from http://gnuwin32.sourceforge.net/packages/make.htm and add path to it in to setenv.bat file

Hi Vitasam,

many thanks for your very helpful tipps!
I've successful installed MinGW and GNU Arm Embedded Toolchain, copied the github (via ZIP file, don't have Git installed),
in this try to C:\MinGW\, created the bat file. 'make -v' is also fine.

Trying 'make' resulted in an error regarding bin/check_qspi_crc

Code: Select all

The file 'check_qspi_crc' exists at C:\MinGW\DMCP_SDK\bin
Is there something i have to modify in the Makefile ?

Hi Thomas,

in which Windows terminal you are running make? Cygwin or something similar? There is a shell message
/usr/bin/sh: bin/check_qspi_crc: No such file or directory

I did test it just in Windows terminal (cmd)

I did it also in Windows terminal cmd, no Cygwin.

Now i moved the Github-Content from the MinGW directory to my users directory,
did am 'make clean', and another 'make', but i get the same error.

Found some hints regarding '/usr/bin/sh' at
https://stackoverflow.com/questions/478 ... on-windows,
but this didn't help.
