Hello

i want to make a ubifs.

I have the MT29F1G08ABAEAW NAND, with 2048 bytes page size and Block size= 64 pages =128K ; so i did :

sudo mkfs.ubifs /home/pengwyn/ti-sdk-am335x-evm-05.06.00.00/targetNFS –F -m 2048 -e 126976 -c 8406 -o ubifs.img

 For -e i used LEB_SIZE = $BLOCK_SIZE - (2 x $PAGE_SIZE)

= 131072-2*2048= 126976

Total size of NAND= 1Gb = 1073741824=0x40000000
The file sytem is put at 0x00600000, so the result size for file system in NAND is :40000000-0x00600000=3FA00000=1067450368

1067450368/126976=8406= parameter for -c

the result is a file of 1.7Mb for a file system of 74,6Mb.
 1° Is it normal ?
 2° is my mkfs.ubifs command OK ?

Because when i flash this ubifs, it doesn't work :

u-boot# mw.b 0x84000000 0xFF 0x500000

 u-boot# mmc rescan

 u-boot# fatload mmc 0 0x84000000 ubifs.img

u-boot# nand erase 0x00600000 0x500000

 u-boot# nand write 0x84000000 0x00600000 0x1B2000

0x1B2000 is the size of my ubifs.img

Thank for any help

Trichet, please stop opening multiple threads on the same issue.

The required calculations are pretty well explained here: http://processors.wiki.ti.com/index.php/UBIFS_Support

I have further explained and provided an example in this thread here: http://e2e.ti.com/support/arm/sitara_arm/f/791/p/268305/941327.aspx#941327

Also here: http://e2e.ti.com/support/arm/sitara_arm/f/791/p/241113/857751.aspx#857751

Best regards,
Miroslav

Hello

sorry to have openned several threads; i didn't know on whic forum to post that...

So i continue on this forum ?

I followed your thread, but get same problem, have you any idea ?

1° mkfs.ubifs command

sudo mkfs.ubifs /home/pengwyn/ti-sdk-am335x-evm-05.06.00.00/targetNFS –F -m 2048 -e 126976  -c 849 -o ubifs.img

-m 2048 is the minimum I/O unit = 2KB for the NAND used in the EVM
-e 126976 is the LEB size which is PEB size minus 2 min. I/O units for overhead = 128K - 2*2K = 124K
-c 849 is the max file system size in LEBs and it is calculated below (result is marked in red so that it is easy to spot)

SP - PEB size = 128KB
SL - LEB size = 124KB
P - total PEBs on device/partition = 1024MB / 128KB = 8192
B - PEBs reserved for bad PEB handling = 1% of P = ~81
O - = SP - SL = 4KB

UBI overhead = (81+4)*SP+O*(P-B-4) = (81+4)*128KB+4KB*(8192-81-4) =10880+32428=43308KB== ~338PEBs

This leaves: 8192 - 338 = 7854 PEBs = 105312KB = ~981MB available data

=> 105312KB /SL = 62208KB/124KB = ~849 LEBs

2° ubinize.cfg file

[ubifs]
mode=ubi
image=ubifs.img
vol_id=0
vol_size=981MiB
vol_type=static
vol_name=rootfs

3° ubinize command

sudo ubinize -o ubi.img -m 2048 -p 128KiB -O 2048 ubinize.cfg

-m 2048 is the minimum flash I/O unit size (page)
-p 128KiB is the size of one PEB
-O 2048 is the VID header offset

4° update kernel board file

{

.name = "SPL",

.offset = 0,

.size = 1 * SZ_128K,

{

.name = "SPL.backup1",

.offset = MTDPART_OFS_APPEND,

.size = 1 * SZ_128K,

{

.name = "SPL.backup2",

.offset = MTDPART_OFS_APPEND,

.size = 1 * SZ_128K,

{

.name = "SPL.backup3",

.offset = MTDPART_OFS_APPEND,

.size = 1 * SZ_128K,

{

.name = "U-Boot",

.offset = MTDPART_OFS_APPEND,

.size = 3 * SZ_128K,

{

.name = "U-Boot Env",

.offset = MTDPART_OFS_APPEND,

.size = 1 * SZ_128K,

{

.name = "Kernel",

.offset = MTDPART_OFS_APPEND,

.size = 40 * SZ_128K,

{

.name = "File System",

.offset = MTDPART_OFS_APPEND,

.size = MTDPART_SIZ_FULL,

5° program the NAND

mmc rescan

fatload mmc 0 0x84000000 ubi.img

nand erase 0x00600000 0x1E0000

nand write 0x84000000 0x00600000 0x1E0000

6° run the NAND

setenv nandsrcaddr 0x00100000
setenv nandroot ubi0:rootfs rw ubi.mtd=7,2048
run nandboot

7° get the error :

Hello

thank you for your reply

I'm wondering if i shouldn't have made modification in linux files to support my NAND (MT29F1G08ABAEA). The NAND is a bit diferent from EVM one (1Gb total size, 128K block, 2K page).

Do you know what files must be modified in the linux part ?

I have modified u-boot for this NAND :

6114.ucr.h

Here is the boot log :

Hi Trichet,

The evm_nand_init() function is part of the def_cfg structure. For the GP EVM it looks like this:

{evm_nand_init, DEV_ON_DGHTR_BRD,
(PROFILE_ALL & ~PROFILE_2 & ~PROFILE_3)},

This means that it will be called for each CPLD profile except 2 & 3. I don't know if you have a CPLD switch on your board or an EEPROM, but you should make sure that the current profile is part of the allowed profiles. Otherwise, this function won't get called.

Best regards,
Miroslav

Hello

the evm_nand_init function is called.

Do you think the following log is OK for my MT29F1G08ABAEA NAND (regarding the way i built the ubi file) ?

Hello

the problem is certainly here in the log :

[ 1.775451] UBI: max. sequence number: 0
[ 1.790924] UBI error: vtbl_check: volume table check failed: record 0, error

Have you any idea ?

Thanks a lot

Here is an excerpt from the source code:

     if (reserved_pebs > ubi->good_peb_count) {
           dbg_err("too large reserved_pebs %d, good PEBs %d",
               reserved_pebs, ubi->good_peb_count);
           err = 9;
           goto bad;
       }

Enable CONFIG_UBIFS_FS_DEBUG in your kernel configuration to see more information. This probably means your UBIFS volume is larger than what is available on your NAND flash.

Best regards,
Miroslav

When you create your UBI image, reserve more blocks for bad block handling. Round to the larger integer, not the smaller.

P - total PEBs on device/partition = 1024MB / 128KB = 8192
B - PEBs reserved for bad PEB handling = 1% of P = ~81

This should be 82, not 81.

Check all your calculations again, but first enable the debug messages and inspect them.

Best regards,
Miroslav

thanks, your are right, i change my calculations:

1° mkfs.ubifs command

sudo mkfs.ubifs /home/pengwyn/ti-sdk-am335x-evm-05.06.00.00/targetNFS –F -m 2048 -e 126976  -c 8106 -o ubifs.img

-m 2048 is the minimum I/O unit = 2KB for the NAND used in the EVM
-e 126976 is the LEB size which is PEB size minus 2 min. I/O units for overhead = 128K - 2*2K = 124K
-c 8106 is the max file system size in LEBs and it is calculated below (result is marked in red so that it is easy to spot)

SP - PEB size = 128KB
SL - LEB size = 124KB
P - total PEBs on device/partition = 1024MB / 128KB = 8192
B - PEBs reserved for bad PEB handling = 1% of P = ~82
O - = SP - SL = 4KB

UBI overhead = (82+4)*SP+O*(P-B-4) = (82+4)*128KB+4KB*(8192-82-4) = 11008+ 32424= 43432KB== ~339PEBs

This leaves: 8192 - 339 = 7853 PEBs = 1005184KB = ~981MB available data

=> 1005184KB /SL = 1005184KB/124KB = ~8106 LEBs

2° ubinize.cfg file

[ubifs]
mode=ubi
image=ubifs.img
vol_id=0
vol_size=981MiB
vol_type=static
vol_name=rootfs

3° ubinize command

sudo ubinize -o ubi.img -m 2048 -p 128KiB -O 2048 ubinize.cfg

-m 2048 is the minimum flash I/O unit size (page)
-p 128KiB is the size of one PEB
-O 2048 is the VID header offset

And i validated the debug in the kernel, but get the same results....:

Expert 2025 points

according to debug i put a smaller value for -c parameter of mkfs.ubifs command

Now i have no error on UBI detection, but file system can't be mounted.

1) My ubi.img is 2Mb size for a 74,6Mb file system : do you think this may be correct ?

2) is my way of programming correct :

U-Boot# mmc rescan

Are you sure your offsets are correct?

Please post your nand_partitions structure from your board config file and also your mtdparts U-Boot variable.

Best regards,
Miroslav

i'm wondering if my ubi.img is good (2Mb for a file system of 74,6M) ?

thank you

thanks

Trichet,

I just noticed that your UBIFS is only 2MB. This isn't normal. Usually the UBIFS is around 2/3 of the uncompressed file system size. Can you try with the UBI image that comes with your SDK?

Best regards,
Miroslav

Hi,

thanks, i have changed my command (run just upper targetNFS repertory) :

sudo mkfs.ubifs --root=targetNFS –F -m 2048 -e 126976 -c 900 -v -o ubifs.img

and i get a 48,2Mb file for ubifs.img

1) is this the good way to copy the ubifs.img to NAND :

U-Boot# mw.b 0x84000000 0xFF 0x7A00000
U-Boot# mmc rescan
U-Boot# fatload mmc 0 0x84000000 ubi.img
reading ubi.img

50593792 bytes read
U-Boot# nand erase 0x600000 0x7A00000

NAND erase: device 0 offset 0x600000, size 0x7a00000
Erasing at 0x7fe0000 -- 100% complete.
OK
U-Boot# nand write 0x84000000 0x600000 0x3040000

NAND write: device 0 offset 0x600000, size 0x3040000
50593792 bytes written: OK

but get allways error :

2) HAve you any clue for the error still there ?

I am out of ideas. The only suggestion I have left is to upgrade the SDK you are using. I have already mentioned multiple times that it is very old and it may contain a lot of old bugs which should been fixed by now in the newer versions.

The UBI layer depends on the MTD layer, which depends on the flash driver. There is also the ECC algo implementation and so on. If even one of these layers doesn't function correctly, the UBIFS is likely to have errors.

Best regards,
Miroslav

thanks a lot for your help i appreciated very much.

Do you know the linux files i should look at where BCH8, ECC, NAND parameters are defined ?

Thanks

0 Miroslav Kiradzhiyski XID over 11 years ago in reply to trichet christophe

TI__Mastermind 25235 points

For SDK v6 (U-Boot 2013.01.01) only BCH8 is used by default. I think these are the related files (or at least some of them):

drivers/mtd/nand/nand_base.c
drivers/mtd/nand/nand_bch.c
include/linux/bch.h
include/linux/mtd/nand.h
include/linux/mtd/nand_bch.h
lib/bch.c

Best regards,
Miroslav

Hi,

thanks for the reply

I can't see where is defined in linux NAND parameters as for example ECC SIZE, OOB SIZE,... as we can define them in the board configuration of the u-boot (am335x_evm.h).

How linux knows these parameters ?

regards

0 Miroslav Kiradzhiyski XID over 11 years ago in reply to trichet christophe

TI__Mastermind 25235 points

Also chech the <u-boot>/drivers/mtd/nand/omap_gpmc.c file. In SDK v6, this is how the BCH private data looks like:

static struct nand_ecclayout hw_bch8_nand_oob = GPMC_NAND_HW_BCH8_ECC_LAYOUT;

static struct nand_bch_priv bch_priv = {
   .mode = NAND_ECC_HW_BCH,
   .type = ECC_BCH8,
   .nibbles = ECC_BCH8_NIBBLES
};

Best regards,
Miroslav

thanks a lot

in the boot log we can see :

[ 1.016784] NAND device: Manufacturer ID: 0x2c, Chip ID: 0xf1 (Micron MT29F1G08ABAEAWP)

It means that the NAND is well recognized .

1) Can we deduce that reading NAND from linux is OK ?

2) is there a way to know under linux prompt if NAND reading is OK ?

Thanks

regards

Trichet, which version of mkfs.ubifs are you using? Check with "mkfs.ubifs -V".

Also check if this answer is relevant to your issue: http://e2e.ti.com/support/embedded/android/f/509/p/202971/725476.aspx#725476

thanks for the reply

i use Version 1.3

I set

setenv nandroot ubi0:rootfs ro ubi.mtd=7,2048

instead of :

setenv nandroot ubi0:rootfs rw ubi.mtd=7,2048

and i can mount the ubifs file system

But i want it to be read/write. Do you know how on line 1199 of \fs\ubifs\super.c :" ubifs_err("cannot mount read-write - read-only media"); the media is declared read only ?

Where a NAND could be declared read only ?

Should i post this on another forum ?

Thanks in advance

Please try a newer version of the mkfs.ubifs command.

thank you for your reply. I've understoud, the ubinize.cfg file must have dynamic in it.

[ubifs]

mode=ubi

image=ubifs.img

vol_id=0

vol_size=112MiB

vol_type=dynamic

vol_name=rootfs

Now i can write a file in NAND, but when i reboot i have the error :

[ 3.939270] UBI error: ubi_io_read: error -74 (ECC error) while reading 12697

6 bytes from PEB 3:4096, read 126976 bytes

[ 3.952819] [<c0017978>] (dump_backtrace+0x0/0x110) from [<c043de4c>] (dump_s

The fact of having written a file in NANd corrupts the UBIFS.

Have you any idea of why writing may not write the good ECC ?

Thanks

Did you write the file to the file system or directly to the NAND flash? Please post exact procedure.
