Hi,
I am working with the Simulink (dual motor with f28069M, Boostxl8301 and the same motors used by Mr.Antonin ), however I wanted to experiment first spinning one motor not both! So I removed the blocks related to MOTOR 2 and left those related to MOTOR 1, and I implemented the host file from his first experiment (TI with Simulink working with F28027) to read serial msjs after addinng the serial monitor to the speed controller
However the motor didnt spin ! There are some errors and weird messages I searched for their answers but I couldn't find a satisfying clear answer from mathwork.
Here are the things that I faced when I (Build, Deploy, & Start) where the hardware is being connected via usb to the pc.
1. Unexpected exception (filesystem::recursive_directory_iterator directory error: The system cannot find the path specified) was caught.
2. When trying to Monitor & Tune this error appierd
Error evaluating 'InitFcn' callback of C28x SCI Transmit block (mask) 'c28069pmsmfocdual/Speed Controller1/Serial Monitor/SCI Transmit1'.
Callback string is 'validateC280xSCI('Tx');
codertarget.registry.registerC280xSCITxBlocks(gcb);'
Caused by
- The SCI module A is already used by another block or by External Mode.
I read however a similar error on Mathwork , I tried to implement the Block from C2806x , still having the same error,
3. When I inserted the SCI block from C2806x lib this appierd. 
I think my questions can be solved easily, please be straight forward as I have read almost all threads on google.!
4. Could these errors be the reason why my motor is not spinning ? Note that Jumpers are set correctly , COM port , serial communication too (hopefully)
5. I read that CCS could lock the COM port how can we Unlock it incase it is locked ?
a. btw why are the rs , Is , base voltage and current in workspace in matlab for Teknic_M2310PLN04K motor are different from its real parameters ?
6. My power supply is 12V/5A I know it is low but isnt it enough for now to just spin the motor ? As I have worked with Motorwate labs and it spinned.
7. While tying to build or monitor which comes first ? and can I plug the hardware with usb and powersupply at the same time when building and monitoring as I want to read the serial msjs when the motor spins.
Thank you for your Aid.
I appreciate your support.
Regards,
