Description

When trying to add a global variable in the variables window in SDK in the debug perspective, I get the following error message:

Target request failed: Could not fetch register "f1"; remote failure reply "E01""

Also, I do not seem to be able to update an existing variable in the variable window.

Solution

This is a known issue. XMD can be used to work around this issue.

Here, XMD can be used to update f0-f7, and there are no errors while updating local variables.
