===================
Applicable Environment:
---------------------------------
Target: ZCU102 BSP
Release: 7.0
===================
In the ZCU102 BSP User's Guide, the offset specified to write the QNX IFS image to QSPI flash storage is 0xC00000 (12M). Since the BOOT.BIN file size has increased (~ 25 MB), the QSPI mappings need to be changed in the IPL to successfully boot. Below is the summary:
--- IPL ---
In qspi.h (located in ../src/hardware/ipl/boards/xzynq-zcu102/):
- IFS Offset have been changed to 0x02000000
- Max size for BOOT.BIN and IFS has been increased to 32 MB.
---
reflash-image.sh and
reflash-ipl.sh ---
- Changed the offset to 0x02000000 for the IFS
- Limit was increased to 32M for both, BOOT.BIN and IFS, when using flashctl.
The following relevant files are attached:
- qspi.h
-
reflash-ipl.sh
-
reflash-image.sh
- BOOT.BIN (built with the modified IPL)
The Bootgen utility, which is used in the mkflashimage script to rebuild the BOOT.BIN file, is available via the Xilinx website -
