Project Releases

Fixed

• Fixed a compilation error when trying to build with the field-control feature.

Fixed

• Improved the reliability of wireless uploads, specifically when switching radio channels between download and pit mode. In general, there should be less of a delay when switching between channels, as well as less “Packet Timeout” errors.

Changed

• Updated the static template to support vexide 0.6.1.

Added

• Added support for differential uploads in vexide 0.6.0. This can be configured using the upload-strategy CLI argument or metadata option.

Changed

• Uploads will now only reupload the ini file (program configuration) if it has changed.
• Redesigned progress bars and other logs to match the styling used by cargo.
• Decreased the amount of log messages that are printed to users by default.
• Relaxed timeout durations on the code responsible for switching radio channels.
• Adjusted our file naming format on flash to match the one used by VEXCode and PROS.

Fixed

• Fixed cargo v5 terminal when using a controller.

Added

• Filesystem Access: cargo-v5 can now list, download, view, and erase files from flash on a brain through the ls, cat, and rm subcommands (NO you can’t delete system files sorry guys :c).
• Event Logs: cargo v5 log allows you to view a brain’s event log directly from your computer, which logs stuff like program runs, port connects/disconnects, device and OS errors, power on/off, field control status, etc…
• Device Listing: cargo v5 lsdev/cargo v5 devices will list all devices currently connected to a brain, as well as their firmware/bootloader version for debugging purposes or checking if a port got disconnected.
• Screenshots: You can save a capture of your brain’s screen with cargo v5 screenshot/cargo v5 sc.
• cargo-v5 will now emit temporary log files for debugging purposes.

Changed

• cargo v5 run will now immediately stop the running program when closed or quit with the ^C escape sequence.

Fixed

• Fixed a minor issue with cargo v5 ls where file load addresses would be incorrectly displayed.

Changed

• cargo-v5 will now cache the locally downloaded template when the fetch-template feature is enabled.

Added

• cargo-v5 will now cache the locally downloaded template when the fetch-template feature is enabled.
• Added the llvm-floatabi field to the armv7a-vex-v5 target spec to support builds on the latest rustc nightly versions.

Fixed

• Fixed an issue with cargo v5 screenshot capturing images with too large of a buffer.
• Fixed a compiler error from the directories dependency when the fetch-template feature was enabled.

Added

• You can now create new vexide projects with the cargo v5 new and cargo v5 init commands.
• Added support for user input in cargo v5 terminal.
• Added the ability to use cargo-v5 as a field controller through the cargo v5 fc command. This can only be used if installed with the optional field-control feature.

Fixed

• Target specification now uses the correct VFPv3 float ABI.
• Uploads will now only be attempted when a successful build occurs.

Added

• Uploads will now switch the radio to the download channel when uploading wirelessly.

Changed

• Switched back to an internal implementation of objcopy for producing binary artifacts. cargo-binutils is therefore no longer required.

Added

• cargo v5 run provides a cargo runner capable of building and uploading a program, running the program, and opening the terminal in one command.

Changed

• Added support for vexide 0.4.0’s new target specification using the ARM hard-float ABI.
• Previous target specification files will now be overwritten.
• The package.metadata.v5 field in Cargo.toml is now no longer required for projects.

Fixed

Switched to the cargo-binutils version of objcopy as an emergency fix for our implementation sometimes producing binaries with undefined behavior.

In order to use this newer version, you will need to install cargo-binutils:

rustup component add llvm-toolscargo install cargo-binutils

Fixed

• Fixed an issue with the object dependency not compiling on windows.
• Fixed an issue with V5 serialport identification on non-linux platforms.

Added

• You can now pass pre-objcopied program binaries (.bin) files to cargo v5 upload using the --file argument.

Changed

• Cut down on some dependencies to improve compile times.

Fixed

• Fixed a bug with the internal implementation of objcopy in cargo-v5 generating invalid user programs.

This is the initial release of cargo-v5. See our summer release post for more information!
