babyshark(terrashark) software update

[Pete Fleming]

 Hi Angel,

  I'm looking to migrate my Raspberry Pi running the baby shark to a Raspberry Pi 4 running 64-bit.

  After investigating the current setup I've identified a few components I'll need updated builds or source for to make this work:
  - adcpps kernel module — needs recompiling against the new kernel
  - sharksend — needs recompiling for 64-bit ARM (aarch64)
  - shark2WinSDR — same
  - ewcontrol — same

  If you're able to share the source code for any or all of these that would be ideal, so I can manage future builds myself. If that's not possible, would it be possible to get precompiled 64-bit ARM binaries?

  The current setup is running well so I'm not looking to change anything functionally, just get it on newer hardware and be able to setup some additional software.

  Thanks!
  Pete Fleming

Pete,

When I made the Raspberry Pi image for Angel it included the Earthworm source code. This included the code for
sharksend. Check your system to see if you can find the file sharksend.cpp. Another file to look for is adcpps.c. This
is the code for the adcpps kernel module.

Hi Larry,

Thanks for the suggestion. I did a search but no source files came up.

Pete,

Take a look inside a tar archive of the earthworm software.  You may need to look in the installation image.

Hi Bob,

I checked the image and didn't find it.

Thanks,

Hi Pete,

Either way you will need to compile EW for the PI4. I don't think there are any precompiled binaries for the PI4. You
can download the current code from here: https://gitlab.com/seismic-software/earthworm

Compiling EW for the first time can be a little daunting. But you should be able to find some online documentation to
help you get the basic modules compiled and running. Once you can create binaries I can send you the source code files
for the missing modules. I have a new sharksend module that includes the shark2WinSDR code. This allows WinSDR to
connect directly to sharksend without the need for the shark2WinSDR module.

Larry,

To start what follows are just possible ideas/thoughts. You and
others may have similar and/or different ideas. I just thought I
suggest ideas as starting point.

Does is make sense to have new "sharksend" module that includes the
"shark2WinSDR" code added to Earthworm source tree? I know the
Earthwork developers have very specific criteria for modules that
are necessary given the core design of Earthworm.

As you know the PsnAdSend source has been part of Earthworm source
code for years. Why I am hoping maybe "sharksend" could be.

"adcpps" may be more challenged by Earthworm to be added as my
sense is "adcpps" is Kernel module. I assume "adcpps" is Linux
kernel specific which might be challenged by Earthworm developers to
be added if there is not OS specific defines in Earthworm for such
situations. Given the Linux developers temperament it is likely
"adcpps" would not be considered to be added to Linux Kernel source
tree and if so maybe github and/or your web site?

I have no idea if source for "ewcontrol" would be for Earthworm
source or on github/your web site. I know nothing about
"ewcontrol", hence you and others will know possibilities for where
makes sense for source to be found.

Hi Larry and Everyone else,

We provide binaries for the Pi cards we use.  Sharksend is now called mohosend same thing.   I will order a Pi4 and get that compile done and get the binaries to anyone.

The shark2winsdr is not needed since there is the same functionality in the send module.  I will need a few days to get the Pi4 to Panama and the compilation should be quick.

Sounds good Angel. I will let you deal with this. I have other things to work on....

Hello Angel,

Is the new upgraded BeagleBone Black with the MOHO Tres, TeraShark image out and available at this time?

Thank you,
