Hello all,
just see with current HEAD of u-boot on an imx6ull based board with SPI NOR
and NAND following behaviour:
=> mtdparts
device nand0 <gpmi-nand>, # parts = 1
#: name size offset mask_flags
0: ubi 0x08000000 0x00000000 0
device nor0 <spi1.0>, # parts = 5
#: name size offset mask_flags
0: spl 0x00010000 0x00000000 0
1: u-boot 0x000c0000 0x00010000 0
2: env 0x00010000 0x000d0000 0
3: env-red 0x00010000 0x000e0000 0
4: rescue 0x00710000 0x000f0000 0
active partition: nand0,0 - (ubi) 0x08000000 @ 0x00000000
defaults:
mtdids : nand0=gpmi-nand,nor0=spi1.0
mtdparts:
mtdparts=gpmi-nand:-(ubi);spi1.0:64k(spl),768k(u-boot),64k(env),64k(env-red),-(rescue)
=>
=> mtd list
List of MTD devices:
* nand0
- type: NAND flash
- block size: 0x20000 bytes
- min I/O: 0x800 bytes
- OOB size: 64 bytes
- OOB available: 0 bytes
- ECC strength: 8 bits
- ECC step size: 512 bytes
- bitflip threshold: 6 bits
- 0x000000000000-0x000008000000 : "nand0"
- 0x000000000000-0x000008000000 : "ubi"
* nor0
- type: NOR flash
- block size: 0x10000 bytes
- min I/O: 0x1 bytes
- 0x000000000000-0x000000800000 : "nor0"
- 0x000000000000-0x000000010000 : "spl"
- 0x000000010000-0x0000000d0000 : "u-boot"
- 0x0000000d0000-0x0000000e0000 : "env"
- 0x0000000e0000-0x0000000f0000 : "env-red"
- 0x0000000f0000-0x000000800000 : "rescue"
until here all is fine, for example an "ubi part ubi" works as
expected ... also doing this command n times, no problems.
Now:
=> sf probe
SF: Detected s25f064l with page size 256 Bytes, erase size 64 KiB, total 8 MiB
=> mtd list
List of MTD devices:
* nand0
- type: NAND flash
- block size: 0x20000 bytes
- min I/O: 0x800 bytes
- OOB size: 64 bytes
- OOB available: 0 bytes
- ECC strength: 8 bits
- ECC step size: 512 bytes
- bitflip threshold: 6 bits
- 0x000000000000-0x000008000000 : "nand0"
- 0x000000000000-0x000008000000 : "ubi"
* nor0
- type: NOR flash
- block size: 0x10000 bytes
- min I/O: 0x1 bytes
- 0x000000000000-0x000000800000 : "nor0"
=>
All MTD devices on nor0 are gone ... also the previous working
"ubi part ubi" fails ...
Adding debug code:
mtd_for_each_device(other)
printf("%s ===== %s\n", __func__, other->name);
shows only:
get_mtd_device_nm ===== nand0
get_mtd_device_nm ===== nor0
?
Anyone sees this behaviour too?
Any hints?
bye,
Heiko
