I select KV30P64M100 MCU. Use slow internal reference clock. But MCU can't work as I try enter debug state. LPC-link2 fail to connect to targe MCU. I thank MCU system clock hasn't set as internal clock. I haven't connect a external OSC to XTAL and EXTAL pins of the MCU. How can I setting on hardware to make MCU work on internal colck after power on. This is my hardware wire connect on MCU.
