I am of course, stupid. Problem was with cut'n'paste -- everything was working but the boot command was messed up and I had no console output.
Maybe not completely my fault? The instructions say: setenv bootargs_console console=ttyS0,115200 setenv bootcmd_mmc 'ext2load mmc 0:1 0x00800000 /uImage; ext2load mmc 0:1 0x01100000 /uInitrd' setenv bootcmd 'setenv bootargs $(bootargs_console); run bootcmd_mmc; bootm 0x00800000 0x01100000' saveenv But when I try doing it like that I get: U-Boot 2014.10+dfsg1-5 (Apr 07 2015 - 21:57:04) Marvell-Sheevaplug SoC: Kirkwood 88F6281_A0 DRAM: 512 MiB WARNING: Caches not enabled NAND: 512 MiB MMC: MVEBU_MMC: 0 In: serial Out: serial Err: serial Net: egiga0 88E1116 Initialized on egiga0 Warning: Your board does not use generic board.

My system boots ok with: bootcmd=setenv bootargs console=ttyS0,115200n8; run bootcmd_mmc; bootm 0x00800000 0x01100000 But I get no console output with : bootcmd=setenv bootargs $(bootargs_console); run bootcmd_mmc; bootm 0x00800000 0x01100000
