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.</P><P><span class="lia-inline-image-display-wrapper" image-alt="pastedImage_3.png"><img src="https://community.nxp.com/t5/image/serverpage/image-id/78315i258B5769C90B23A8/image-size/large?v=v2&amp;px=999" role="button" title="pastedImage_3.png" alt="pastedImage_3.png" /></span></P><P><span class="lia-inline-image-display-wrapper" image-alt="pastedImage_1.png"><img src="https://community.nxp.com/t5/image/serverpage/image-id/78353iA0B1DF1DE165AE66/image-size/large?v=v2&amp;px=999" role="button" title="pastedImage_1.png" alt="pastedImage_1.png" /></span><span class="lia-inline-image-display-wrapper" image-alt="pastedImage_2.png"><img src="https://community.nxp.com/t5/image/serverpage/image-id/78266iDD0EA1DED3C717AF/image-size/large?v=v2&amp;px=999" role="button" title="pastedImage_2.png" alt="pastedImage_2.png" /></span></P></BODY></HTML> Thu, 29 Nov 2018 05:03:59 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/How-to-set-on-hardware-on-No-OSC-using/m-p/816569#M49492 yyz_dms 2018-11-29T05:03:59Z Re: How to set on hardware on No OSC using. https://community.nxp.com/t5/Kinetis-Microcontrollers/How-to-set-on-hardware-on-No-OSC-using/m-p/816570#M49493 <HTML><HEAD></HEAD><BODY><P>使用MCUXpresso IDE新建基于<A href="https://mcuxpresso.nxp.com/en/select">SDK_2.4.1_MKV30F64xxx10</A>的工程后，在Clocks Tool里可以看到默认就是使用内部时钟源的。<BR />请问你是用的是哪个版本的<A href="https://www.nxp.com/support/developer-resources/software-development-tools/mcuxpresso-software-and-tools/mcuxpresso-integrated-development-environment-ide:MCUXpresso-IDE">MCUXpresso IDE</A>，官网好像并没有中文版。</P><P><span class="lia-inline-image-display-wrapper" image-alt="Clocks Tool.png"><img src="https://community.nxp.com/t5/image/serverpage/image-id/78612i2A56D8F9EE0A512F/image-size/large?v=v2&amp;px=999" role="button" title="Clocks Tool.png" alt="Clocks Tool.png" /></span></P><P></P><P>硬件方面注意<BR />pin<BR />26&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;RESET_b&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;上拉10k电阻，对地接100nf电容<BR />21&nbsp;&nbsp; &nbsp;PTA4&nbsp;&nbsp; &nbsp;NMI_b &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;上拉10k电阻<BR />19&nbsp;&nbsp; &nbsp;PTA2&nbsp;&nbsp; &nbsp;JTAG_TDO/TRACE_SWO&nbsp;&nbsp; &nbsp;上拉10k电阻即可</P><P><span class="lia-inline-image-display-wrapper" image-alt="2.1.3.4.1 RESET_b and NMI_b.png"><img src="https://community.nxp.com/t5/image/serverpage/image-id/78538i76D7113A0085BE29/image-size/large?v=v2&amp;px=999" role="button" title="2.1.3.4.1 RESET_b and NMI_b.png" alt="2.1.3.4.1 RESET_b and NMI_b.png" /></span></P><P><span class="lia-inline-image-display-wrapper" image-alt="debug interface.png"><img src="https://community.nxp.com/t5/image/serverpage/image-id/78572iE33199B66F9D3478/image-size/large?v=v2&amp;px=999" role="button" title="debug interface.png" alt="debug interface.png" /></span></P><P>Best Regards,</P><P>Robin</P><P style="min- padding: 0px;">&nbsp;</P><P>-----------------------------------------------------------------------------------------------------------------------<BR />Note: If this post answers your question, please click the Correct Answer button.
