After my hectic office schedule, I managed to devote some time on the issue and finally I could find the answer. I thought to share my finding with this message board for future developers who might have the same confusion as I had. Here are the details:- 1) IXP425 core always boots in Little endian mode only. If we choose Big endian mode during compilation, we need to SWAP the bytes during program download/flashing so that the XSCALE core can always see the code in little endian only. 2) BIG endian mode is only related to data storage. So, if enabled processor will read/write the data in Big endian mode. 3) Code execution always in little endian mode only. Any thoughts will be highly appreciated. Thanks and regards, Sujoy Ray. __________________________________ Yahoo!
