SWO Interrupt - SWO Overflow

I have problems with SWO trace. The "SWO Interrupts" shows an event OVERFLOW within the "Table" tab continuously as shown in the following picture.


Why does SWO overflow occur so often? I also get many wrong interrupts within the "Statistics" tab. These are Interrupts that i never use in my project.


It seems to me the SWO configuration is correct when I download my firmware with the debugger.

I am using iMXRT1050 with a custom board and LPC-Link2 and i apply the configuration according to the following link.

SWO with NXP i.MX RT1064-EVK Board 


My MCUXpresso version is MCUXpresso IDE v11.1.1 [Build 3241] [2020-03-02] and the used SDK version is SDK_2.x_EVKB-IMXRT1050.


Kind regards,
