MK20DX128VFM5 forced to bootloader

Hello NXP,

We are using MK20DX128VFM5 as open SDA for K66 controller. K20 and K66 is also interfaced to a SOC module(running Linux) through an USB hub. We were able to program K66 through an #open SDA using JTAG(Keil uvision).

But when we tried rebooting the Whole system,the K20 gets forced into Bootloader Mode.

So we are unable to debug application and run the debugger, serial terminal and mass storage for programming the K66.


Please help us in resolving the Issue.

Thanks in advance.
