Dear Sir/Madam,

I am using MK20DX128Vlf5 microcontroller for my USB project.I  am using usb_host:Host_STACK bean for my project. the interrupt priority defined in the generated file is below.

The problem is when I add extra periodic interrupts of 1ms and 15us and 15us(all are minimal priority). 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.

 

Thanks and Regards,

A.Kathirkamu
