Failed to read all registers from target Failed to read all registers from target

When I change variables from live expression and other areas during Prohe debug, I get the error "Failed to read all registers from target" and unfortunately I couldn't find a solution. I am using the latest version of stm32cube 1.18.1. There was no such jata before!

I am using Stm32f767zi processor. I tried with both st link v2 and isol version but this error is not resolved.

Hello @hanNL ,

Try enabling suspension of watchdog in Debugger settings. Please refer to this thread : Why do I get error: CM4 Failed to read all registers FAILED to REGISTER Values from the target.

May this thread help you!

Unfortunately, those solutions are useless. It's a problem with the version. I'll try it on older versions. This problem doesn't exist in v13.2.

It is the same for me: since updating the CubeIDE to 1.19.0 (from 1.14), I always get the message "Failed to read all registers from target" when I modify a value in the "Live Expressions" window.
None of the solutions above helped.

I'm having the same problem; when I change a variable in free expressions, the value changes, but the message "Failed to read all registers from target" is still displayed.
