The usb code is not working properly when i put any snippet inside the ISRs of the interrupts. When I remove the snippet. The usb code is working properly(that the pendrive gets attached to the k20 controller). What goes wrong here?Please help me.</P><P></P><P>Thanks and Regards,</P><P>A.Kathirkamu</P></BODY></HTML> Tue, 03 Jan 2017 12:06:49 GMT kathirkamuannak 2017-01-03T12:06:49Z USB K20 Regd https://community.nxp.com/t5/Kinetis-Microcontrollers/USB-K20-Regd/m-p/656646#M40145 <HTML><HEAD></HEAD><BODY><P>Dear Sir/Madam,</P><P>I am using MK20DX128Vlf5 microcontroller for my USB project.I&nbsp; am using usb_host:Host_STACK bean for my project. the interrupt priority defined in the generated file is below.</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/4150iF5A907711DB6889F/image-size/large?v=v2&amp;px=999" role="button" title="pastedImage_3.png" alt="pastedImage_3.png" /></span></P><P>The problem is when I add extra periodic interrupts of 1ms and 15us and 15us(all are minimal priority).
