AR# 47572

Zynq-7000 AP SoC, Boot IOP - BootROM night hang if a NAND Boot Image is Malformed or Corrupted

Description

In boot from NAND, the BootROM might hang if it encounters a malformed or corrupted image stored in the NAND flash. In such cases, the BootROM does not complete the boot process and does not go into ErrorLockDown state.

Solution

Impact:
Minor. There is no problem with correct boot images. This issue only occurs with corrupted or malformed images, in which case the boot process would not be successful anyway.
Work-around:
If the boot image header is not working, then inspect the image data on the NAND flash for correctness.
Configurations Affected:
Systems that use boot from NAND controller.
Device Revision(s) Affected: Refer to (Xilinx Answer 47916) - Zynq-7000 Design Advisory Master Answer Record
