Hi
It depends on which version of Ride7 and RKit-ARM you use:
+If you use latest verrsion of Ride7 (7.10.0000) and RKit-ARM (1.10.0000)
The stm32 library version 2.01 is included and you do not need to add it.
The gcc tools has been update.
You can use the CircleOS version 2.
+If you use older version of Ride7 (7.10.0000) and RKit-ARM (1.10.0000).
You can not use CircleOS version 2 so keep using the version 1.7.
Best regards,
Matloub
