Issue: Compiler errors with Nucleo F401RE (Closed: Fixed)

I get these compiler errors:

Error: Identifier "OS_TASKCNT" is undefined in "mbed-rtos/rtx/RTX_CM_lib.h", Line: 93, Col: 32 Error: Identifier "OS_CLOCK" is undefined in "mbed-rtos/rtx/RTX_CM_lib.h", Line: 95, Col: 32 Error: Identifier "INITIAL_SP" is undefined in "mbed-rtos/rtx/RTX_CM_lib.h", Line: 241, Col: 37 Error: Identifier "OS_SCHEDULERSTKSIZE" is undefined in "mbed-rtos/rtx/RTX_CM_lib.h", Line: 241, Col: 79

Hello Patrick H.,

there was a question asked reporting same errors, where I provided an answer that nucleo targets are not yet supported by mbed-rtos. There's could be more concise error message that target is not supported than it's currently there. I'll look into it.

Thx for reporting the issue.

Hi Patrick, I encountered the same issue with you for Nucleo-L152RE, then I fixed this issue by following steps: 1. open RTX_Conf_CM.c which located in \mbed-rtos\rtx 2. add new Nucleo target in 3 locations A. find: #ifndef OS_TASKCNT B. find: #ifndef OS_SCHEDULERSTKSIZE C. find: #ifndef OS_CLOCK

Here is the example of modifying mbed-rtos for adding Nucleo-L152RE: http://mbed.org/users/stanly88/code/mbed-rtos/

Have fun! Stanly
