This implements an SD/MMC protocol analyzer for the Logic (http://www.saleae.com) software for Saleae logic analyzers.
Documentation for the Saleae Logic Analyzer SDK can be found here: https://github.com/saleae/SampleAnalyzer
That documentation includes:
- Detailed build instructions
- Debugging instructions
- Documentation for CI builds
- Details on creating your own custom analyzer plugin
To use this analyzer, simply download the latest release zip file from this github repository, unzip it, then install using the instructions found here:
https://support.saleae.com/faq/technical-faq/setting-up-developer-directory
This repository is setup with Github Actions to automatically build PRs and commits to the master branch.
However, these artifacts automatically expire after a time limit.
To create and publish cross-platform releases, simply push a commit tag. This will automatically trigger the creation of a release, which will include the Windows, Linux, and MacOS builds of the analyzer.
This section only applies to downloaded pre-built protocol analyzer binaries on MacOS. If you build the protocol analyzer locally, or acquire it in a different way, this section does not apply.
Any time you download a binary from the internet on a Mac, wether it be an application or a shared library, MacOS will flag that binary for "quarantine". MacOS then requires any quarantined binary to be signed and notarized through the MacOS developer program before it will allow that binary to be executed.
Because of this, when you download a pre-compiled protocol analyzer plugin from the internet and try to load it in the Saleae software, you will most likely see an error message like this:
"libSimpleSerialAnalyzer.so" cannot be opened because th developer cannot be verified.
Signing and notarizing of open source software can be rare, because it requires an active paid subscription to the MacOS developer program, and the signing and notarization process frequently changes and becomes more restrictive, requiring frequent updates to the build process.
The quickest solution to this is to simply remove the quarantine flag added by MacOS using a simple command line tool.
Note - the purpose of code signing and notarization is to help end users be sure that the binary they downloaded did indeed come from the original publisher and hasn't been modified. Saleae does not create, control, or review 3rd party analyzer plugins available on the internet, and thus you must trust the original author and the website where you are downloading the plugin. (This applies to all software you've ever downloaded, essentially.)
To remove the quarantine flag on MacOS, you can simply open the terminal and navigate to the directory containing the downloaded shared library.
This will show what flags are present on the binary:
xattr libSimpleSerialAnalyzer.so
# example output:
# com.apple.macl
# com.apple.quarantineThis command will remove the quarantine flag:
xattr -r -d com.apple.quarantine libSimpleSerialAnalyzer.soTo verify the flag was removed, run the first command again and verify the quarantine flag is no longer present.
CMake and a C++ compiler are required. Instructions for installing dependencies can be found here: https://github.com/saleae/SampleAnalyzer
The fastest way to use this analyzer is to download a release from github. Local building should only be needed for making your own changes to the analyzer source.
