      Hi fraengers,

      We have successfully reproduced the issue. At first glance this seems like it could simply be that a part of the chain is overloaded. This could be some buffer, the connection itself or even the host system.
      We will of course check whether we can improve this, but at this point we cannot make any promises.

      As a workaround lowering the sampling frequency and/or the J-Link connection speed reduces the load, stabilizing the data sampling.

      Best regards,
      SebastianB
