      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi &lt;A class="jx-jive-macro-user" href="https://community.nxp.com/people/jeremyzhou"&gt;jeremyzhou&lt;/A&gt;,&amp;nbsp;&lt;/P&gt;&lt;P&gt;Thank you for your help. The following is my reply for the question:&amp;nbsp;&lt;/P&gt;&lt;P style="padding-left: 30px;"&gt;1) 2) This is my first time to this board, but have the other one used this board before. I asked him how to use this board, and he said he only downloaded the code of LED blinking by using&amp;nbsp;MCUXpresso and Freelink.&lt;/P&gt;&lt;P style="padding-left: 30px;"&gt;3) The "Active faults"&amp;nbsp;is the fault at MCUXpresso. (Note: This problem happened when "PROGRAM FLASH" is 0x7000_0000 or 0x6000_0000 and "Driver" of&amp;nbsp;&lt;SPAN&gt;"PROGRAM FLASH" is&amp;nbsp;MIMXRT1060_SFDP_QSPI.cfx&lt;/SPAN&gt;)&lt;span class="lia-inline-image-display-wrapper" image-alt="pastedImage_8.png"&gt;&lt;img src="https://community.nxp.com/t5/image/serverpage/image-id/109534i0968C3AEE578EFAE/image-size/large?v=v2&amp;amp;px=999" role="button" title="pastedImage_8.png" alt="pastedImage_8.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P style="padding-left: 30px;"&gt;a) I haven't tried, and I will try this method.&lt;/P&gt;&lt;P style="padding-left: 30px;"&gt;b) I had tried to use "Serial Downloader", but appear the following error message. (Note: {SW5, SW6, SW7} = {0x0, 0x0, 0x1}, USB cable connected at J41/the socket of the nearest Freelink.)&lt;/P&gt;&lt;P style="padding-left: 30px;"&gt;&lt;span class="lia-inline-image-display-wrapper" image-alt="pastedImage_14.png"&gt;&lt;img src="https://community.nxp.com/t5/image/serverpage/image-id/110059i31506CE4B7EFC756/image-size/large?v=v2&amp;amp;px=999" role="button" title="pastedImage_14.png" alt="pastedImage_14.png" /&gt;&lt;/span&gt;&lt;span class="lia-inline-image-display-wrapper" image-alt="pastedImage_15.png"&gt;&lt;img src="https://community.nxp.com/t5/image/serverpage/image-id/109979iB65EE887484D66E3/image-size/large?v=v2&amp;amp;px=999" role="button" title="pastedImage_15.png" alt="pastedImage_15.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN style="color: #51626f; background-color: #ffffff;"&gt;Have a great day,&lt;/SPAN&gt;&lt;BR style="color: #51626f;" /&gt;&lt;SPAN style="background-color: #ffffff; color: #51626f;"&gt;Jhewei Syu&lt;/SPAN&gt;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
