Serial communication failed in host-target communication

HI everyone,

I have set a motor control environment to learning motor control

• LAUNCHXL-F28379D
• BOOSTXL-DRV8305EVM
• 24V pmsm with hall sensor

and I ran "mcb_param_est_f28379D_DRV8305.slx" and "mcb_param_est_host_read.slx"

Unfortunately, when I load the model onto the target and run the host model, I get a serial connection error message.

The offset calibration model and other models work perfectly, so I assume that all settings (COM port et cetera) are correct.

Error report:

An error occurred while running the simulation and the simulation was terminated

Caused by:

Serial communication failed.

Error in 'mcb_param_est_host_read/Algorithm/SignalConditioning/ErrorConditions' (line 26)

(error(message('mcb:blocks:SerialComFailure')));

Thank you fpr your heip! Kind regards!

Hi @Nanoeffekt

I understand that the error prompts up when you load the model onto the target hardware and run the model.

In the mcb_param_est_host_read.slx file, update the COM port in the following 3 blocks, Host Serial Setup, Host Serial Receive and the Host Serial Transmit block.

Additionally you can also refer to a similar user case posted in the MATLAB Answer community-

I hope this solves the issue and you are able to proceed further!

Hi,

I have set the COM ports correctly for the three blocks! This is not the cause of the problem. I have also read all the similar answers on this topic, but unfortunately these could not solve the problem either...any other ideas?

Thank you!

Hi, can you let me know in which MATLAB version are you facing this issue?

If COM port is locked by another application, you may likely to see the message. Is this issue still prevails?
