Zynq-7000 AP Soc – 2013.3 SDK / 14.7 iMPACT NAND programming known issues

Description

This Answer lists all the known issues related to SDK and iMPACT programming of NAND in Zynq-7000 AP SoC.
 
To address all questions related to Zynq-7000 AP SoC, see the Zynq-7000 AP SoC Solution Center (Xilinx Answer 52512).

Solution

Its up to the user to identify the proper use case and apply the workaround suggested.
 
IMPORTANT: Always verify that your flash is included in the list of SUPPORTED devices (Xilinx Answer 50991).
 
NOTES:
 
1. Usually the workaround provided in the Xilinx Answers target Xilinx Evaluation Boards (zc702 and zc706) so minor modifications may be necessary for custom boards.

To assist in these modifications, a brief description of the Environmental Variables used by iMPACT and SDK is provided in (Xilinx Answer 59272).

2. If none of the previous use cases apply, please follow the debug steps described in (Xilinx Answer 59311).
 
Below are use cases of the known issue related to different versions of silicon and JTAG chain structures.
