Response to unsigned binary in secure boot

Hi,

Does a SecureBoot-enabled device get bricked if one flashes a regular image (not signed) onto it? What is the response of the processor to a .bin that is not signed or signed with incorrect keys? Does it simply raise HAB events at boot level and wait for a signed image to be flashed?

Thanks

Hello,

 

  All along the boot  procedure and until the boot image is executed, the HAB logs the

encountered errors and warnings. If the boot fails - secure serial bootloader (SDP) 

starts.

Have a great day,

Yuri
