HummingBird RISC-V Software Development Kit, Release 0.1.3

This is release version 0.1.3 of HBird SDK.

• Build

  • Important changes about build system:

    • The SoC and RTOS related makefiles are moving to its own folder, and controlled By
      build.mk inside in in the SoC/ or OS/ folders.
    • Middlware component build system is also available now, you can add you own middleware or library
      into Components folder, such as Components/tjpgd or Components/fatfs, and you can include
      this component using make variable MIDDLEWARE in application Makefile, such as MIDDLEWARE := fatfs,
      or MIDDLEWARE := tjpgd fatfs.
    • Each middleware component folder should create a build.mk, which is used to control
      the component build settings and source code management.
    • An extra DOWNLOAD_MODE_STRING macro is passed to represent the DOWNLOAD mode string.

  • Change openocd --pipe option to -c "gdb_port pipe; log_output openocd.log"

  • Remove -ex "monitor flash protect 0 0 last off" when upload or debug program to avoid error
    when openocd configuration file didn't configure a flash

  • Add cleanall target in <HBIRD_SDK_ROOT>/Makefile, you can clean all the applications
    defined by EXTRA_APP_ROOTDIRS variable

  • Fix size target of build system

• SoC

  • hbird and hbirdv2 SoC cores only support e203 and e203e now.
  • Support Nuclei Studio NPK feature(required 2022.01 release), see NPK Introduction in zh
