Q: I'm following the quick start guide document to try to initially load and run the u-boot with GDB and Openocd, I've been follow the document strictly but can't make it, why?
A: The board you received may already have some bootable image in the on board SPI Flash, which may run immediately after you power on. In this case, try to set the boot mode switch to position 0 before performing the initial GDB loading and running of u-boot.
