I have a target system that has a BOOT.BIN already loaded into its QSPI flash, but when I boot PetaLinux, there is no /dev/mtd. Doing "cat /proc/mtd" returns no results. Can I re-create the mtd partitioning from within PetaLinux? Or is the only solution to load a new BOOT.BIN that was built with the proper MTD settings via Xilinx tools? And how big does mtd0 need to be for a 7z045?
