AR# 47598

Zynq-7000 SoC Boot IOP - BootROM stops searching for boot image after first 16 MB for Quad-SPI x8 and SRAM/NOR

Description

After a system boot, the BootROM searches for a boot image. It starts at the beginning address of the boot device (offset 0x0). 

The design intention is for the BootROM to search up to 32 MB. This search limit occurs in failover and multi-boot situations.

 

Solution

Impact:                                                Minor
Work-around:                                     None. Boot images must be within the 16 MB limit.
Configurations Affected:                  Systems that boot from Quad-SPI in x8 parallel  mode or the NOR interface.
Device Revision(s) Affected:          Refer to (Xilinx Answer 47916) Zynq-7000 Device Advisory Master Answer Record
