Hi,

I'm trying to build a u-boot binary containing default configuration.

I created my configuration include file:

``` #define MTDIDS_DEFAULT "nand0=nand_flash" #define MTDPARTS_DEFAULT "mtdparts=nand_flash:256k(bootstrap)ro,512k(uboot)ro,256k(env1),256k(env2),-(sys)" #define CONFIG_BOOTARGS "ubi.mtd=4 root=ubi0:root1 rootfstype=ubifs console=ttyS0,115200 earlyprintk mtdparts=atmel_nand:256k(bootstrap)ro,512k(uboot)ro,256k(env1),256k(env2),-(sys)" #define CONFIG_BOOTCOMMAND "ubi part sys;ubi read 0x22000000 kernel1;bootm 0x22000000#conf@1" ```

``` => mtdparts mtdparts variable not set, see 'help mtdparts' no partitions defined

defaults: mtdids : nand0=nand_flash mtdparts: mtdparts=nand_flash:256k(bootstrap)ro,512k(uboot)ro,256k(env1),256k(env2),-(sys) => env print arch=arm baudrate=115200 board=sama5d3_xplained board_name=sama5d3_xplained bootargs=ubi.mtd=4 root=ubi0:root1 rootfstype=ubifs console=ttyS0,115200 earlyprintk mtdparts=atmel_nand:256k(bootstrap)ro,512k(uboot)ro,256k(env1),256k(env2),-(sys) bootcmd=ubi part sys;ubi read 0x22000000 kernel1;bootm 0x22000000#conf@1 bootdelay=3 cpu=armv7 mtdids=nand0=nand_flash soc=at91 vendor=atmel

Environment size: 555/131067 bytes ```

As you see, MTD partitions are visible as defaults. But not active.

I could modify my bootcommand, and add "mtdparts default;", but maybe I am missing something.

So, my question is: How can I activate MTD partitions on default environment.

Thank you,

Arek Marud

PS. I'm using Atmel's u-boot forked repository.
