I'm trying to setup my UltraZed board to load the application from a tftp server.
Using u-boot from the "Out of Box release RC3", this version cannot seem to access the Flash storage, so cannot save it's configuration:
U-Boot-PetaLinux> sf probe
Invalid bus 0 (err=-19)
Failed to initialize SPI flash at 0:0 (error -19)
Am I missing some obvious step?
