Hi,
I am trying to program Nuvoton M058LBN using ULINK2. But every time when I download code to flash memory it is showing me "SWD communication failure".
Can anybody help me with this issue?
You're in the best position to actually fix the connectivity issue.
You could try options to "connect under reset", if there is evidence it is connecting at all.
Perhaps review and explain the connection as you have wired it, and whether the board/chip is otherwise functional or not.
Be more specific as to when, exactly, that occurs.
Is it before the download starts?
Is during the download?
Is it after the download, during verification?
etc, etc, ...
Is it a manufacturer's dev board, or your own design?
Has it ever worked?
