I 'm trying to figure out how to make my nexys video boot from qspi flash. I tried several offsets I found around the net...the sdk project build successfully as well as the programming of FPGA and flash (following the steps in the digilent tutorial) but...nothing happens after that. i tried the same simple project (the gpio example) without qspi and it works when " run as configuration" mode. Now i suspect the offset used for flash image to be guilty. (my block design is just microblaze with debug module, gpio leds, uart (which i dont use in software), and the qspi with 50khz clock).
I am still a novice at this stage so i don't know how to debug my project. My questions:
-how to estimate a good FLASH_IMAGE_BASEADDR for my nexys video card? (in theory I can only imagine that the size of the programming files would give me a hint but even here, i don't know how to move on
-Any simplified steps to debug the app on the board?
....Thank you guys in advance, you are doing a great job helping the rest of mortals down here....
