Please double check the USB connection. You may make reference the FRDM-K64F USB circuit. (MK24 USB is same with K64)</P><P><span class="lia-inline-image-display-wrapper" image-alt="pastedImage_2.png"><img src="https://community.nxp.com/t5/image/serverpage/image-id/66838i56A2705549887BA7/image-size/large?v=v2&amp;px=999" role="button" title="pastedImage_2.png" alt="pastedImage_2.png" /></span></P></BODY></HTML> Thu, 01 Nov 2018 08:21:44 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/MK24FN1M0VDC12-Large-current-consumption-during-USB/m-p/846742#M50965 miduo 2018-11-01T08:21:44Z
