Problem demo downloading to controller

I’m using an Olimex SAM7-EX256 and I’m trying the CrossWorks demo  (using version 1.7) and though it lists a demo for AT91SAM7X256 on the list of demos, the closest I actually find in the zipfile is for a at91sam7s256.

Not sure if it’s compatible, but it compiles fine, but fails to verify on download.

Any suggestions as I would like to use it as a starting point to learn the IwIP stack and want to make sure I have a working starting point.

Thanks in advance

According to it is in the FreeRTOS\Demo\lwIP_Demo_Rowley_ARM7 folder.

The current demo project is not compatible with ftdi based JTAGs( Such as the Olimex JTAG Tiny i use).
In the CrossWorks 1.7 release which added support for them, they ship a new re-worked target script with improved timing for those JTAG types.

Once I replaced the script with the one shipped with the current version if crossworks, download and verify works great.
