How to load the application into VPE1 from VPE0 ? (cat XYZapp >/dev/vpe1 ?) Exactly. > 2. Is there any sample "Hello World" application for this ? > 3. Any specific tool chain needed ? I recommend you refer to the file, MIPS® SDE Programmers' Guide (.pdf). http://www.mips.com/products/product-materials/processor/software/ It's easy to build the sample with SDE. And ever I program a sample to output some messages from UART to validate AP/AP. I think even you can implement the same to display something from the LED.
