Dear,
I've got a flash split into 2 bank of 32 Mb. From linux view there is only one flash with a size of 64 Mb (define in the DTS). My goal, do the same thing with u-boot to read a ubi file with a size > 32 Mb which contains my uImage, but mtdparts still to see 2 flash device and i can"t open the ubi file.
Linux MTD partitions are : 4 cmdlinepart partitions found on MTD device fc000000.flash Creating 4 MTD partitions on "fc000000.flash": 0x000000000000-0x000000100000 : "Primary" 0x000000100000-0x000000180000 : " uboot" 0x000000180000-0x0000001a0000 : "uboot_var" *0x0000001a0000-0x000004000000* : "rfs"
u-boot config : MTD : #define MTDIDS_DEFAULT "nor0=fc000000.flash,nor1=fe000000.flash" #define MTDPARTS_DEFAULT "mtdparts=fc000000.flash:0x100000(Primary)ro,0x080000(uboot )ro,0x020000( uboot_var),-(RFS)"

Only the CONFIG_SYS_LBLAWAR0_PRELIM is used to realized this feature ?
Sébastien.
