Restrict Debug Console Access of IMX6

tengri — Mon, 13 Nov 2017 10:50:39 GMT

Hello Guys,

Is there a way, like we do in Secure JTAG, to secure the debug console access (or UART access) of IMX6 ? i.e. only to restrict it to end-user ?

Thanks in advance

Okay I figured out that this can be done with the aid of Secure HAB. Can anyone point me to the up to date IMX CST Tool ?

Following link does not seem to work :

Freescale Code Signing Tool for the High Assurance Boot library. Provides software code signing support designed for use…

Hi Anuradha,

The link is properly working, but you need to be logged in on NXP website.

Hope this will be useful for you.
Best regards!

Hi Carlo, well for some unknown reason now it's working (I already logged in befor). Anyway i know how to sign u-boot and kernel seperately. Is there any document that explains how to it for dtb ?

Thanks
