When attempting to run "hello world" after following the pdf tutorial ... exactly as describe in this pdf:
ZedBoard: Zynq-7000 AP SoC Concepts, Tools,andTechniques A Hands-On Guide to Effective Embedded System Design (dated 8/22/12)
I get to the point within the tutorial where I RUN Hello World, but nothing happens. It sits around 47% and does nothing. Sometimes I get a message indicating to setup the STDIO Configuration with proper COMM settings.
Any attempt to RUN appears to lock up COM4.
The ONLY course of action to get free Cypress Serial COMM4 ... is to reboot my laptop.
Once I get this lock up condition... I can power cycle the ZED Board and the Device Manager shows that the Cypress Serial (COM4) remains and is not getting released. This is for J14 - USB - UART
These release OK:
1) The CYPRESS USB to SERIAL adapter appropriately releasing and being assigned. (J17 USB-JTAG)
2) The USB Serial Converter appropriately releasing and being assigned. (J14 - USB - UART)
I also noticed that since it's not releasing the Com4 port it's also attempting to run multiple instances of Hello World. These I can not disable.
To get back my COM4 Port (AT ALL) I have to reboot the computer.
I have tried several things: Reading many instructions, FAQ's, Support Pages, etc. I have changed Jumper Settings, Modified configuration settings, reloaded drivers for Cypress COM4, read through the *.tcl and *.hdl files ....
Could use someones help here.
