New build-gnuradio

GNU Radio
1

Mr. UHD, being a man of some comedic genius, has once again
roto-rootered the file structure on the web server that serves up
UHD Firmware/FPGA images :slight_smile:

So, I had to change build-gnuradio to deal with the new world.

Is it because the version names changed?

Can you wget the whole directory and pick out the first tar.gz file?

This is what I now do:

 #
 # First, get listing of

ettus.com/downloads/uhd_releases/master_images
# We use spider mode, and use -r to descend
#
wget -np -r --spider
http://www.ettus.com/downloads/uhd_releases/master_images >tmp$$ 2>&1

 #
 # Now search the resulting log file for .tar.gz files that match

the appropriate
# pattern.
#
grep ‘UHD-images.*tar.gz’ tmp$$ |sed -e ‘s@.*Removing @http://@’
|sort -r |head -1 >tmp2$$

Then

 #
 # Fetch the tar file (whose name is in ../tmp2$$)
 #
 fn=`cat ../tmp2$$|sed -e s/.$//`
 wget -nd $fn >/dev/null 2>&1

If you mess with the paths, be aware the OE reciep that grabs the
firmware and repackages it for the E100 uses this recipe:

http://cgit.openembedded.org/cgit.cgi/openembedded/tree/recipes/uhd/uhd-firmware.inc

You can use your imagination to work out what path I am depending on.

  • What do you mean by “the appropriate pattern” in the above comment, present in
    your script? Sorry, I am a newbie.

The pattern given by the “grep” regular expression and “sed” regular
expression above, in the script.

The right address is: www.sbrac.org/files/build-gnuradio

Yup, sorry about that!

Hi Marcus,

the appropriate
# pattern.
#
grep ‘UHD-images.*tar.gz’ tmp$$ |sed -e ‘s@.*Removing @http://@’
|sort -r |head -1 >tmp2$$

BTW, in one of the recent mails you addressed you site with:
www.sbrac.org/build-gnuradio which gives 404 error.

The right address is: www.sbrac.org/files/build-gnuradio

Thanks in advance.
