Hi hassan,

I understand that you have built and deployed code on the launchpad by unchecking the “Boot from flash” option in Model Configuration options. The code is left uncleared from the flash even after disconnecting and reconnecting the power to the board.

You can refer to the following MATLAB Answer where a similar issue has been resolved by using “Code Composer Studio” to erase the code on the board:

You can also rebuild and deploy the same or different code to the board as this will automatically clear the previous program on the board.

You can refer to the following thread from MathWorks Support Team to understand how to run the code from RAM despite booting from flash, if the reason to uncheck the “Boot from flash” option is to use the RAM on the board:

I hope this answers your query.
