Hello ,

I am running a modified model of pmsm closed loop control . the model was running fine in freemaster till yesterday but now the connection is getting disconnected frequently and when i try to connect it again it shows no board detected error.

I have attached the slx file of the model

Thank you

Dear Sriram,

if FreeMASTER was working earlier, you need to focus at the changes you made in the application code. It is out of scope of this forum to analyze your code, I can only give you some general comments. You can also send more information about your customization of the motor control application to the dedicated motor-control community.

General reasons why FreeMASTER can become un-responsive when using a serial line:

Application main-loop gets too busy and FreeMASTER operates in a polled mode (FMSTR_POLL_DRIVEN). A solution may be to use interrupt-driven communication or to lower the communication baudrate.
System overload - if application is spending too much time in interrupts, not leaving enough of run time to communication processing.
FreeMASTER reads a different ELF file than actually running in the MCU. This would cause the variables to be read from different addresses. A solution would be to reload proper ELF file or use the TSA runtime symbolic tables.
System clock, pins or other configuration changes, resulting in UART becomes misconfigured.
Physical damage of the chip (?) Does the FreeMASTER work better if you try your "yesterday's" version? If not, then a physical damage could be relevant.

Regards,
Michal

freemaster runs fine on previous versions of my model so i think the hardware is fine
