SDP 7.0 ZCU102 BSP: Boot with the QNX IPL from QSPI flash storage   ________________________________________________________________________ Applicable Environment ________________________________________________________________________ Topic: ZCU102 Boot from QSPI Flash Storage SDP: 7.0.0 Target: ZCU102 ________________________________________________________________________ Question ________________________________________________________________________ For the ZCU102 target, how do I boot with the QNX IPL from QSPI flash storage? ________________________________________________________________________ Recommendation ________________________________________________________________________ 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 - https://www.xilinx.com/.
