Unreleased

Added

• Payloads can now use the ELF format (but must still be built for a fixed address)
• New payload runtime functions startCycleCounter, getCycleCounterValue, getMonitorAbiVersion

0.6 - 2024-02-16

Added

• New microbenchmark for FPGA latency

Changed

• Timer period is now expressed using the std::chrono::microseconds data type
• A Xilinx BSP (board support package) is no longer necessary to compile Bmboot
• GoogleTest dependency has been made optional

Fixed

• add_bmboot_payload now correctly adds the linker option -specs=nosys.specs

0.5 - 2024-01-30

Added

• New payload runtime functions getBuiltinTimerFrequency, getBuiltinTimerValue
• Payloads now embed an explicit header. This enables validation of ABI compatibility, load address and program size.

Fixed

• Better handling of high-traffic console output

0.4 - 2023-12-12

Added

Fixed

• Better reliability of detection of running monitor

0.3 - 2023-11-06

Added

• New function overload toString(DomainIndex)

Changed

• The payload runtime function startPeriodicInterrupt has been split into setupPeriodicInterrupt and startPeriodicInterrupt

0.2 - 2023-10-30

Added

• New function disableInterruptHandling

Changed

• Interrupt callbacks are now of type std::function (backwards-compatible change)
• The payload runtime function configureAndEnableInterrupt has been replaced by setupInterruptHandling and enableInterruptHandling

0.1 - 2023-10-25

Added

• First versioned release
