STM32CubeCLT 1.19.0 released

We are pleased to announce that the release 1.19.0 of STM32CubeCLT is available.

What is new in 1.19.0:

  • Support for ST Arm Clang toolchain
  • Maintenance of the previous version
  • Updated in accordance with STM32CubeIDE v1.19.0

Main fixed issues in 1.19.0:

No fixed issue to report. 

Know problems and limitations in 1.19.0:

  • The user must specify the path of STM32CubeProgrammer/bin as argument when executing ST-LINK_gdbserver as shown in the example below:
    ST-LINK_gdbserver.exe -cp/c/ST/STM32CubeCLT/STM32CubeCLT/STM32CubeProgrammer/bin
  • For MAC OS no paths for "CLANG_GCC_CMSIS_COMPILER" and GCC_TOOLCHAIN_ROOT.
    The workaround is the following 
    • Open terminal
    • Then source the file /etc/profile
    • Then re do the echo command on these two variables but we must use the same terminal
