上記のようなエラーが出てきてしまいました。

このような場合は、どうすればよいでしょうか
----------------------------------------------------
おそらくリンカーファイルが二つリンクされています。
ソースファイルとともに
F28035.cmd
F28035_RAM_lnk.cmd
というファイルが左に見えていると思います。
通常ですとActive Build CongiurationでRelease/Debugを選ぶとどちらかが選択されるのですがそれがうまくいかなかったようです
右クリックでどちらかをExclude File(s) for Build
としてみてください
Relaseとしたい場合は
F28035_RAM_lnk.cmd
をexclude
Debugでビルドしたい場合は
F28035.cmd
をexcludeしてください
