PKC Verification failed while loading kernel and ramdisk images

I’m working on Jetson TX1 L4T R28.2, but 2 device just can’t boot,

the error message looks like:
PKC Verification failed while loading kernel and ramdisk images

Any help is appreciated, thank you so much.

hello lyg151351,

below message seems interesting, did you still working with L4T?

Failed to boot Android

sure, I burned R28.2(ubuntu 16.04) on my TX1

Is there anything unusual about the host PC? I’m wondering if the content used to flash with might have had something unusual happen to it. You might want to give a detailed description of the host PC install.

Hi lyg151351,

Can those 2 problem device boot? Any update?
