Task count unchanged/Error in Task

Hi All, I am trying to get the PC demo version (FreeRTOS5.3.0, OpenWatcom1.8, FreeDOS1.0) running on an 80186 simulator. The serial and parallel tests seem to work OK but I am getting a number of errors from other tasks which I am not sure how to fix, any suggestions what it can be? Maths task count unchanged! Incorrect number of tasks running! Semaphore take count unchanged! Dynamic priority count unchanged! Error in multi events tasks! Error in tick hook to co-routine communications! Error in block time test tasks! Error in fast block time test tasks! Maths task count unchanged! Alt blocking queues count unchanged! Incorrect number of tasks running! Error in multi events tasks!  Thanks,
Hans.

Do you have the NO87 environment variable set on the target computer/emulator? regards.

Hi Richard, Yes, I set it before running the demo, C:set NO87=1 C:rtosdemo Thanks,
