change partitions in nand flash

Hi Daniel,

Have you set the mtdparts variable in U-Boot accordingly? Also the nandsrcaddr and nandroot variables?

I see you are trying to have a dual NAND boot. Is your NAND flash size 256MB?

If it is, then please show the whole boot log.

You will most probably have the following error inside it:

UBI error: vtbl_check: volume table check failed: record 0, error 9

This means that the reserved PEBs are more than the good/available PEBs in your NAND flash.

I believe that this is happening because the UBIFS is trying to use more NAND memory than there is available, because you have one more kernel image and one more ubi.img which take up more space (In the case with 256MB NAND flash size).

I tried using 2 kernel images with only one UBI file system and it seems like it is working, except for the matrix browser. Perhaps with bigger NAND flash it would be possible without errors.

These are the last 3 entries in the am335x_nand_partitions[] structure inside the board file:

    {
        .name           = "Kernel 1",
        .offset         = MTDPART_OFS_APPEND,   /* Offset = 0x280000 */
        .size           = 40 * SZ_128K,
    },
    {
        .name           = "Kernel 2",
        .offset         = MTDPART_OFS_APPEND,   /* Offset = 0x780000 */
        .size           = 40 * SZ_128K,
    },
    {
        .name           = "File System",
        .offset         = MTDPART_OFS_APPEND,   /* Offset = 0xc80000 */
        .size           = MTDPART_SIZ_FULL,
    },

This is how I program the NAND flash and then set the U-Boot variables:

Hi,

The kit has 256MB of flash size. I reviewed the proceeding, but not found mistakes. Attached is the boot log and the environment variables. The ubi image is based on ../ti-sdk-am335x-evm-05.06.00.00/filesystem/arago-base-tisdk-image-am335x-evm.tar.gz, in other words, the two filesystem images totaling more less 64MB.

The commands used to generate ubi filesystem were:

mkfs.ubifs -q -r base-rootfs-am335x-evm -m 2048 -e 131072 -c 1988 -o ubifs.img
ubinize -o ubi.img -m 2048 -p 128KuB -s 512 

please, let me know if you see the inconsistency.

Hi Daniel,

You should read this and make all the calculations for your case: http://processors.wiki.ti.com/index.php/UBIFS_Support

Best regards,
Miroslav

Here is my (unfortunately unsuccessful) attempt to get it to work.

First I added these lines to the nand_partitions structure inside the kernel board file:

    {
        .name           = "Kernel 1",
        .offset         = MTDPART_OFS_APPEND,   /* Offset = 0x280000 */
        .size           = 40 * SZ_128K,
    },
    {
        .name           = "Kernel 2",
        .offset         = MTDPART_OFS_APPEND,   /* Offset = 0x780000 */
        .size           = 40 * SZ_128K,
    },
    {
        .name           = "File System 1",
        .offset         = MTDPART_OFS_APPEND,   /* Offset = 0xc80000 */
        .size           = SZ_64M+SZ_16M,
    },
    {
        .name           = "File System 2",
        .offset         = MTDPART_OFS_APPEND,   /* Offset = 0x5c80000 */
        .size           = MTDPART_SIZ_FULL,
    },

The partition table is the following: 5MB kernel1, 5MB kernel2, 80MB FS1, the rest is for FS2.

Then I followed the UBIFS guide I mentioned to create a UBI file system for a smaller MTD device (64MB). Here are my steps and calculations:

1) I used the filesystem archive provided in the TI SDK and extracted it to a ubifs/ folder.

2) mkfs.ubifs -r ubifs/ -F -o ubifs.img -m 2048 -e 126976 -c 501

-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 501 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 = 64MB / 128KB = 512
B - PEBs reserved for bad PEB handling = 1% of P = ~6
O - = SP - SL = 4KB

UBI overhead = (B+4)*SP+O*(P-B-4) = (6+4)*128KB+4KB*(512-6-4) = 3288KB = ~26PEBs

This leaves: 512 - 26 = 486 PEBs = 62208KB = ~61MB available data (this is to be used later in the ubinize.cfg file as vol_size)

=> 62208KB/SL = 62208KB/124KB = ~501 LEBs

3) Create a ubinize.cfg file containing:

[ubifs]
mode=ubi
image=ubifs.img
vol_id=0
vol_size=61MiB
vol_type=static
vol_name=rootfs

vol_name is the name you will be using when setting the nandroot U-Boot variable later (I'll mark it in green.)

4) Create ubi.img file with the following command:

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

5) Execute the following commands to write your files to NAND and then set the environment:

U-Boot# nand erase.chip

NAND erase.chip: device 0 whole chip
Erasing at 0xffe0000 -- 100% complete.

The result of the mtdparts command should look like this:

Then set these:

U-Boot# setenv nandsrcaddr 0x780000
U-Boot# setenv nandroot ubi0:rootfs rw ubi.mtd=8,2048

and run nandboot:

U-Boot# run nandboot

The kernel failed at mounting the rootfs:

VFS: Cannot open root device "ubi0:rootfs" or unknown-block(0,0)

I'm not sure why this is happening. This was an unsuccessful attempt, but I'm sure it can be done and that I'm missing something little.

You can try creating a ubi.img containing 2 volumes inside it, similar to what is shown here: http://www.linux-mtd.infradead.org/faq/ubi.html#L_ubi_mkimg

Best regards,
Miroslav

Ok Miroslav, I followed your recommends and now it is working well. The main problem was in size definition of ubi image generation. Here is a link that complement your answer http://processors.wiki.ti.com/index.php/UBIFS_Support#Creating_UBIFS_file_system.

thank you
