LPC51U68 deep sleep SWD

Hi, I'm using the LPC51U68 SDK version 2.9.0, and I tried the sample lpcxpresso51u68_utick_wakeup.
After programming this sample, I'm not anymore able to connect the chip for reprogramming or mass erase (via MCUXpresso)
I'm using CMIS-DAP V2.263 on MCU-LINK debug probe
Why the SWD is not working? I searched on U68 documentation, but I have not found any info about.
This is very big issue, I need to have my application that at RESET/POWER ON enters in deep sleep, and awakes fron internal timer or external event (GPIO trigger), but in this case no further FW program/update is allowed!!
Could you help me? How to solve this trouble?

Hello, to recovery the board you need to put in ISP mode and erase  the flash.

Best regards,
Pavel
