Short Description
The TE0722 is configured to boot from flash with JTAG in cascade mode. If you configure the TE0722 Flash with wrong Boot.bin (for ex. you use Xilinx default or wrong FSBL. Or you insert additional applications file into the boot.bin without necessary workarounds), the Zynq - PS is running into a state, in which the FPGA and the Flash is not accessible via JTAG.This workaround set the FPGA in JTAG independent mode on startup to erase the corrupt flash content.
Procedure
For this case, you can try the following steps without guarantee for success:
- Disconnect TE0722 and close all Xilinx Programs.
