Secure boot on ZCU102 evaluation board

Hi Team, 
 
During secure booting,if the device is given a  image with wrong keys, the device will go to lockdown mode.
Is it possible or is there any way  to come out of the lockdown mode?
 
Thank you.

Re: Secure boot on ZCU102 evaluation board

Hi @adavappa,

Yes, it is possible to come out of lockdown mode, by changing the boot mode to JTAG, if you are booting from QSPI32/24 boot mode. Once the boot mode changed simply power cycle the board and boot to JTAG boot mode for replacing the QSPI image (if QSPI has a wrong key image). In short lockdown to recover, you need to power cycle or assert PS_POR_B signal.
