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)"
CFI config :
#define CONFIG_SYS_FLASH_CFI
#define CONFIG_FLASH_CFI_DRIVER
#define CONFIG_SYS_FLASH_BASE 0xFC000000
#define CONFIG_SYS_FLASH_SIZE 64
#define CONFIG_SYS_FLASH_PROTECTION 1
#define CONFIG_SYS_FLASH_USE_BUFFER_WRITE
#define CONFIG_SYS_FLASH_BANKS_LIST { CONFIG_SYS_FLASH_BASE,
CONFIG_SYS_FLASH_BASE+ ((CONFIG_SYS_FLASH_SIZE*1024*1024)/2)}
#define CONFIG_SYS_LBLAWBAR0_PRELIM CONFIG_SYS_FLASH_BASE
#define CONFIG_SYS_LBLAWAR0_PRELIM (LBLAWAR_EN | LBLAWAR_64MB)
#define CONFIG_SYS_MAX_FLASH_BANKS 2 /* number of banks */
#define CONFIG_SYS_MAX_FLASH_SECT 512 /* sectors per device */
u-boot log :
mtdparts
device nor0 <fc000000.flash>, # parts = 4
#: name size offset mask_flags
0: Primary 0x00100000 0x00000000 1
1: uboot 0x00080000 0x00100000 1
2: uboot_var 0x00020000 0x00180000 0
3: rfs *0x01e60000* 0x001a0000 0 => Expected
to have 0x3CC0000
active partition: nor0,0 - ( Primary ) 0x00100000 @ 0x00000000
defaults:
mtdids : nor0=fc000000.flash,nor1=fe000000.flash
mtdparts: 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.
