v1.390: cross compilation, SAM demodulators

DANGER: DO NOT do a manual Debian/Linux upgrade to your Kiwi! (update: but it's okay now)
So it appears the Debian project and Beaglebone.org have stopped making updates to the Debian 8 (Jessie) release. For the Beagle, Debian 8.11 seems to be the last release. It has been run by a number of customers for a long time and also by us. So it seems safe now for Kiwi owners generally to do an upgrade and get the benefit of whatever security patches there have been between 8.5 and 8.11.
To do this login as root using ssh/PuTTY and use the following commands. (this can not be done from the Kiwi admin console tab)
If you haven't logged in this way in a while remember that your Debian root password has likely been changed to either the Kiwi admin password or the Kiwi's serial number if no Kiwi admin password has been set. The Debian root password has not been touched if you had set it to something other than the default of having no password.
See this post for details: http://forum.kiwisdr.com/discussion/1801/v1-354-security-improvements-debian-root-password-no-longer-unset-blank
A few minutes after the reboot the Kiwi server should be responding again. If you login to the Beagle and type the "dog" command you should see:cdp mst (stops the Kiwi server) cd pkup (shell alias for "apt-get -y install debian-archive-keyring; apt-get update") pkug (shell alias for "apt-get -y dist-upgrade") (lots of output, takes roughly 10 minutes) reboot
There is still the open question of how the Kiwi distribution, and thousands of Kiwi customers, will migrate to the current Debian 9 (Stretch) and/or Debian 10 (Buster) releases which are available for the Beagle. This needs time for research as there are many issues involved.Debian 8.11 BeagleBoard.org Debian Image 2016-05-13 Linux kiwisdr 4.4.9-ti-r25 #1 SMP Thu May 5 23:08:13 UTC 2016 armv7l GNU/Linux

v1.390: cross compilation, SAM demodulators
From the "I'm not working on it except when it interests me" department:
I'm interested in feedback about the SAM demods from the BCB DX crowd. But remember that this code is just lifted from wdsp and I don't know much about it. There are some tunable PLL parameters that could potentially be optimized. Please read the Kiwi operation manual for full details: kiwisdr.com/quickstart/index.html#id-faq-samv1.390 April 23, 2020 Performance improvements: Suggested by @howardsu on Kiwi forum: remove -DDEBUG so assert()'s are not evaluated. Added new "make debug" target to revert to compiling with -DDEBUG defined. Christoph's cross-compilation changes: added "make xc" target that allows cross-compiling on development host. Alternative to slow compiles on Beagle during development. See file CROSS_COMPILE for complete details. Added synchronous AM (SAM) demodulators from Warren Pratt's wdsp package via the Teensy-ConvolutionSDR implementation: github.com/DD4WH/Teensy-ConvolutionSDR See the Kiwi operation manual for more information: kiwisdr.com/quickstart/index.html#id-faq-sam Synchronous AM modes: SAM, SAL, SAU, SAS User interface changes: Use keyboard shortcut 'A' to toggle the SAM modes (sorry, 's' and 'S' were taken). As always type 'h' or '?' to see the list of all keyboard shortcuts. Bugfix: Adjusting the passband via a "/width" or "/low,high" entry in the frequency box is now "sticky" i.e. remembered when returning to the mode. Just like when changing the passband via the 'p' and 'P' keyboard shortcuts. Restore as usual by shift-clicking on the mode button.
