Hi
after adding just one GPIO to Xilinx spartan-3A webserver demo design, the system started to fail
everything starts up ok, but after setting IP, at the time where lwip should start there microblaze seems to stall badly, so badly that XMD reports that reset is activated (what isnt the case) as long the webserver is not running the system is stable
the same happens when the filesystem image and webserver elf are loaded from micro-SD card (connected to that extra GPIO) or with XMD over JTAG
when the system gets stuck, it really looks like microblaze is in some weird run-away stuck state and cant recover any more
