Cannot run and debug Simulink model on some LAUNCHXL-F28379D boards

Hi,

I'm facing some issue on a few of the LAUNCHXL-F28379D boards I have while trying to deploy and run my Simulink model on it.

It seems that the code is flashed on the board, but it cannot "run" so I cannot change values and dynamically do my observations.

The below error is thrown by Simulink when trying to connect to the board.

C28xx_CPU2: If erase/program (E/P) operation is being done on one core, the other core should not execute from shared-RAM (SR) as they are used for the E/P code. Also, CPU1 will be halted to determine SR ownership for the CPU which will run the Flash Plugin code, after which CPU1 will be set to run its application. User code execution from SR could commence after both flash banks are programmed.

The revision of the launchpad is Ver: 2.0, MATLAB version is R2022a Update 5 (9.12.0.2039608), CCS version is 12.0.0.

The board is powered using the USB port.

The part that is confusing me is that the same Simulink model works on a few of the same launchpad boards I have while it does not work with some.

I tried looking for the "System cannot find the file specified" error, however I was unable to find a thread associated with such an error.

I would appreciate any leads/guidance/redirection/suggestion anyone has!

Thanks :)

Hello Shreyas,

The above issue may be because of several reasons including port access permissions and physical connection issues.

One of the most common reason for this is the COM port issue where the serial port name mentioned here, i.e COM5 may be different from the one in device manager. You can use the following Matlab answers link to follow the steps to check the seial port name and change it if required:
