Hi Ragu

please look U-boot error: ** Unrecognized filesystem type **

environment & bootcmd may be saved by previous versions so

one can run clearenv && reset or env default -a && saveenv && boot

as explained at http://boundarydevices.com/u-boot-on-i-mx6/

Hello Igor,

Thanks for the reply... basically Im very new to linux and new to imx processors.... I need to boot, add a kernel and a rootfs to imx6q sabresd board... I have referred https://community.freescale.com/docs/DOC-95015 to boot and https://community.freescale.com/docs/DOC-95017 to compile a kernel.. Now I have a u-boot.imx, uImage and imx6q-sabresd.dtb ready. Bt when I follow the steps to prepare a SD card using the above mentioned links, I'm facing the issue(board boots with the prints as shown below)....

Please help me to prepare the SD card, so that I boot, add a kernel to my sabresd board...

If you are providing me the commands step by step that would be of great help. Thank you in advance.

Hi Ragu

one can recheck file "README.imximage" how to flash SD card :

Setup a SD Card for booting

--------------------------------

The following example prepare a SD card with u-boot and a FAT partition

to be used to stored the kernel to be booted.

I will set the SD in the most compatible mode, setting it with

255 heads and 63 sectors, as suggested from several documentation and

howto on line (I took as reference the preparation of a SD Card for the

Beagleboard, running u-boot as bootloader).

You should start clearing the partitions table on the SD card. Because

the u-boot image must be stored at the offset 0x400, it must be assured

that there is no partition at that address. A new SD card is already

formatted with FAT filesystem and the partition starts from the first

cylinder, so we need to change it.

You can do all steps with fdisk. If the device for the SD card is

/dev/mmcblk0, the following commands make the job:

1. Start the fdisk utility (as superuser)

fdisk /dev/mmcblk0

2. Clear the actual partition

Command (m for help): o

3. Print card info:

Command (m for help): p

Disk /dev/mmcblk0: 1981 MB, 1981284352 bytes

In my case, I have a 2 GB card. I need the size to set later the correct value

for the cylinders.

4. Go to expert mode:

Command (m for help): x

5. Set card geometry

Expert command (m for help): h

Number of heads (1-256, default 4): 255

Expert command (m for help): s

Number of sectors (1-63, default 16): 63

Warning: setting sector offset for DOS compatiblity

We have set 255 heads, 63 sector. We have to set the cylinder.

The value to be set can be calculated with:

cilynder = <total size> / <heads> / <sectors> / <blocksize>

in this example,

1981284352 / 255 / 63 / 512 = 239.x = 239

Expert command (m for help): c

Number of cylinders (1-1048576, default 60032): 239

6. Leave the expert mode

Expert command (m for help): r

7. Set up a partition

Now set a partition table to store the kernel or whatever you want. Of course,

you can set additional partitions to store rootfs, data, etc.

In my example I want to set a single partition. I must take care

to not overwrite the space where I will put u-boot.

Command (m for help): n

Command action

e extended

p primary partition (1-4)

p

Partition number (1-4): 1

First cylinder (1-239, default 1): 3

Last cylinder, +cylinders or +size{K,M,G} (3-239, default 239): +100M

Command (m for help): p

Disk /dev/mmcblk0: 1967 MB, 1967128576 bytes

255 heads, 63 sectors/track, 239 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Disk identifier: 0xb712a870

Device Boot Start End Blocks Id System

/dev/mmcblk0p1 3 16 112455 83 Linux

I have set 100MB, leaving the first 2 sectors free. I will copy u-boot

there.

8. Write the partition table and exit.

Command (m for help): w

The partition table has been altered!

Calling ioctl() to re-read partition table.

9. Copy u-boot.imx on the SD card

I use dd:

dd if=u-boot.imx of=/dev/mmcblk0 bs=512 seek=2

This command copies the u-boot image at the address 0x400, as required

by the processor.

Now remove your card from the PC and go to the target. If evrything went right,

the u-boot prompt should come after power on.

I think you can also post this to meta-fsl-arm mailing list,
