Hi Robert, Fom my understanding when I'm booting from the SD-card opensuse is using boot.script
See serial log (after modifications below) *U-Boot SPL 2014.10 (Oct 20 2014 - 20:57:40)* *spl_register_fat_device: fat register err - -1* *spl_register_fat_device: fat register err - -1* *spl_load_image_fat: error reading image u-boot.img, err - -1* *spl: ext4fs_open failed* *spl_load_image_ext_os: error reading image args, err - 0* *U-Boot 2014.10 (Oct 20 2014 - 20:57:40)* * Watchdog enabled* *I2C: ready* *DRAM: 512 MiB* *NAND: 0 MiB* *MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1* **** Error - No Valid Environment Area found* **** Warning - bad CRC, using default environment* *Net: <ethaddr> not set.
