In all silicon revisions, the boot process caused by the PS_POR_B reset signal must not be interrupted by the assertion of the PS_SRST_B reset signal.
In pre-production silicon, the system may not lock down securely and the results are unpredictable.
In production silicon, the system will lock down if PS_SRST_B is asserted while the BootROM is executing after a POR reset.
Refer to UG585 TRM v1.7 or later, chapter 6 for a discussion.
The result of this situation is not well defined. The design intention in this situation is to cause a secure lockdown condition.
|Work-around:||The system designer should design and operate their system to ensure that this scenario does not occur.|
|Device Revision(s) Affected:||Refer to (Xilinx Answer 47916) Zynq-7000 SoC Silicon Revision Differences.|
