Re: [myhdl-list] bitbake recipes to build myhdl, xstools, iverilog and gtkwave using Yocto

Hi Jeremy,
If the synthesis tool is the goal not 
many boards running Linux don't fit the bill.
Xilinx and Altera have the market
 for the synthesis and bit file generation.

I started in Yocto before FPGAs since
 I have worked in Linux for many years.
I created images for the BeagleBoard, 
PandaBoard, BeagleBone, and ZedBoard using Yocto.

My thinking was the ZedBoard was the answer at $395.00.  
Learning Linux and FPGAs takes
quite an effort.  That is where MyHDL and Xess came.
The XulA2 which comes in 2 verisons XulA2-LX9 or XulA2-LX25 
 The XulA2 at $69 StickIt!-MB $20 (for GPIO to Pi ) and Raspberry Pi 2 B at $35 makes a low cost with a small foot print. 

Yocto which started in 2010 from Openembedded 
appears to be growing in users at the highest rate.

If you just want Linux with Ethernet, USB, and HDMI
it takes about 675MB image. This would need a mouse
or touch screen HDI since it supports a virtual keyboard.  

Now if you want OpenCV with C920 camera support 
and kernel-dev xterm git 
 jasper gsl gsl-dev python-netserver python-pygtk
 python-pygtk-dev python-numpy liba52 liba52-dev
 libmad libmad-dev libmad-staticdev 
 chkconfig v4l-utils python-imaging parted 
 python-distribute python-pyrex python-pexpect
 gperf tree libav libav-dev 
 x264 x264-dev libav libav-dev opencv opencv-samples
 cmake opencv-apps python-opencv tcl tk
The requires an image of 868.2 MB.

I have the software for what I described on 32 GB
running Debian on a Raspberry Pi 2 B. 

I think the next step is the Compute Module which is based
on the RaspberryPi designs.  I also think that Yocto will
be developing for that as well.  Most of the people at
Yocto work for WindRiver which is an Intel company.  
Also Intel is buying Altera.  

GNURADIO and OpenCV are where the FPGA opportunites 
will be running some ARM processor. Let me know if you have any questions.

 Hi Edward,

Please forgive my ignorance, but isn't this ultimately limited as a development tool because there is no synthesis tool on the rpi ?

Thanks,
Jeremy

Hi all,Dave the current verison of Xstools is 6.0.15?Current vesion of MyHDL is 1.0.0 is that correct?
My goal is create a Yocto image for the Raspberry Pi 2 B that provides the necessary tools to use MyHdl with Xstools, Iverilog & GTKwave.  The combo of RaspberryPi 2 B with a StickIt-MB & XulA2  would make a great low-cost development tool for developing and testing FPGAs.

I currently have a working core-image-sato that I can install myhdl using python setup.py develop instead of  python setup.py install.  I also can install Iverilog and GTKWave compiling from source on the target.  
 I can ssh to the Raspberry Pi 
 ssh -Y 192.168.1.136

I can also download my repo https://github.com/develone/jpeg-2000-test.git
Then cd into the jpeg-2000-test/ipython_fixbv.Where I can execute python test_jpegEnc.py.The above does a dwt on an image.cd myhdlgit log

    Correctly display events when dumping using the FST format

    This patch is from Tony Bybell and fixes a segmentation fault when dumping
    an event to a FST file.

iverilog -h
Usage: iverilog [-ESvV] [-B base] [-c cmdfile|-f cmdfile]
                [-g1995|-g2001|-g2005] [-g<feature>]
                [-D macro[=defn]] [-I includedir] [-M depfile] [-m module]
                [-N file] [-o filename] [-p flag=value]
                [-s topmodule] [-t target] [-T min|typ|max]
                [-W class] [-y dir] [-Y suf] source_file(s)

See the man page for details.

gtkwave -v
Gtk-Message: Failed to load module "canberra-gtk-module"

GTKWave Analyzer v3.3.65 (w)1999-2015 BSI

I am in the process of creating the recipes to install the above tools on the image.The process that I am using is found at https://github.com/develone/raspberrypi2_yocto.git

I am using an AMD 6 core with 16 GB and takes about 2 hours to create the image.
