USB K20 Regd

[kathirkamuannak]

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

Hi kathirkamu annakamu

Could you clarify:

What Stack version are you using?

You mentioned that you add interrupts, this mean that you specify another interruption or that you are modifying USB interrupt?

Could you share your project? or add more information of how your configure your project?

Regards
