GUI Never Deleted Original PIN numbers: app,overloy

Sheldon01

I am using the GUI app.overlay program to modify the pin locations.  I changed the UART0 pins to be P0.00 to P0.03 (from P0.05 to P0.08) so I could free up the default pin numbers of the UART0 pins for my own design (a custom board).  However, the new pins appear on P0.00 to P0.03 but the ones on the original pins are still there?  How can I delete them?  Is that not possible in the GUI?  I was hoping to just modify the development board to my custom board which doesn't use the exact same locations.

Thanks!

    Hello Sheldon,

    That is odd. I'll have to get back to you on this tomorrow. Could you check if you are using the newest version of the extension in the meantime?

    Hi Elfving,

    I have attached a picture of the VSC version.  I downloaded it just last week.  I am not familiar with how to find out the version of the 'extension' is (unless it is in the image I captured).

    Could it be that I have the development board selected and it doesn't think the pins can change on the development board?  I didn't change much from the development board so I went with that as a start and plan to modify it as needed.

    Hi again Sheldon, thanks for waiting.

    No that should be fine. People acctually often use the development board as a starting off point when developing their own board. Modifying it (or mainly adding an overlay file to it) is a typical use-case. 

    So I've just opened up a peripheral_uart sample here, and headed to the DTS GUI by pressing the "Device Tree" action. Then I've opened the pin-view by pressing the SoC icon in on the buttom right, and I'm left with this view.

    You can see that some of the blue icons here have an additional arrow next to them. The arrow signifies that an additional role of &uart0 is also assigned to this pin.

             

    Here I can now drag &uart0-RX from P0.08 to P0.09. This will result in the additional arrow shaping dissappearing, and a few blue field appearing on P0.09. We've now moved RX[DEFAULT] to this pin.

    To move RX[SLEEP] as well, simply drag-and-drop again. 

    Does this work for you?

    Regards,

    Elfving
