Hello,

it could be that due to some wrong flash programming the device is not able to exit form reset.

Configure the debugger to attach (instead of connect) to a running device and then reset the device.

Use the Target Configuration menu (in UDE PLS interface) to do so.

Regards,

Giuseppe

thank you pretty much ,the SBC is enable in the plant state even if I do not plug in KL15(I only plug in KL30) ,but after I download SW and re_initial SBC, the SBC will not power on MCU if I don't plug in KL15.

so this is a fool mistake made by me.
