Zynq-7000 AP SoC ZC706 Evaluation Kit - Issues when restoring the ZC706 flash


While restoring the ZC706 flash contents using XTP247, an issue can arise when attempting to connect to the target.

Using SDK to Program the Flash with Xilinx Platform Cable USB II and boot.mcs file from the zc706_restore_flash directory results in the program entering a loop.


If you encounter this behavior, it is likely that the Zynq-PS is in Secure Lockdown.

When in Secure Lockdown mode, the DAP is disabled from the JTAG chain.

This means that only the PL will be available, resulting in QSPI indirect programming failures. 

When using the ZC706 board, set the Configuration mode to JTAG cascaded (SW11=All Zero=000000) and power cycle the board.

Then retry the boot.mcs script.
