More SATA boot questions

[JeffMichalski]

I reviewed the discussion at:

http://imxcommunity.org/group/imx53quickstartboard/forum/topics/how-to-prepare-sata-disk-for?comment...

Then set out to try this but I can not seem to get the QSB the default Ubuntu Image from a SATA hard disk drive.

I am sure I missing some obvious step like how does uBoot get onto the hard drive.  The uImage file I am working with is uImage-744-g27fdf7b taken directly from the /boot directory from the QSB.

I documented the procedure that I have followed in some detail below:
Any help from someone who has this working would be much appreciated.

 Steps taken so far:

0. Verified 2.1 version silicon

1. Copy the uImage-744-g27fdf7b to my PC TFTP server home directory

2. Rename the file to uImage

3. Soldered on a dip switch onto SW1

4. Changed R46 from a pull-up to a pull-down (the board no longer booted uBoot once I changed R46 to pull-down I so I added an external switch to set R46 as either pull-up or pull-down as needed)

5. Reset R46 to pull-up.
Set all SW1 dip switches off
(Should be QSB default configuration)

6. Executed uBoot commands from section 6.2 and repeated in 8.3 i.MX53 Start Linux User's Guide)

setenv serverip 192.168.180.89
setenv bootfile uImage
saveenv
dhcp
sata info
sata write ${loadaddr} 0x800 0x2000
setenv bootargs_sata 'setenv bootargs ${bootargs} console=tty1 root=/dev/sda1 rootwait rw video=mxcdi1fb:BGR24,XGA di1_primary tve'
setenv bootcmd_sata 'run bootargs_base bootargs_sata; sata read ${loadaddr} 0x800 0x2000; bootm'
setenv bootcmd 'run bootcmd_sata'
saveenv
reset

7. According to HW reference manual (pp 46,60)

Set Boot Switch (SW1) - Switch 6 On (shorts pin 6 to pin 15)
- Switch 8 On (shorts pin 8 to pin 13)
Set R46 to pull-down

8. Reset the QSB

No response on the serial port.

There are several questions I have after reading the docs:

What is in uImage (does it include uBoot? does it include rootfs or just the kernel proper?)

Does the SATA drive need to be partioned or pre-formatted before uImage is loaded?

Does rootfs need to be copied over to the drive first (It was not clear to me if instructions section 7 in the Linux Start User Guide apply or are an alternative load procedure)

Lastly, are there any Linux kernel configuration file sthat need to be modified (ie fstab, grub.conf ....)?

Hi, Do you solved the question?

I meet the same problem as you. When I sata info, I get as follows:

MX53-ARD-DDR3 U-Boot > sata info

AHCI 0001.0100 32 slots 1 ports 3 Gbps 0x1 impl SATA mode

flags: ncq stag pm led clo only pmp pio slum part

timeout exit!

timeout exit!

SATA Device Info:

S/N:

Product model number:

Firmware version:

Capacity: 0 sectors

SATA device 0: Model:  Firm:  Ser#:

            Type: Hard Disk

            Capacity: not available

It looks different with your result such as I cannot get the SATA's capacity but you can. Why SATA device cannot be recognized?
