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!
