Can't boot up from nand after using Mfgtool

Hello there,

 

I have board with imx28. Our sd doesn't work due that we don't have eeprom to apply the polarity patch. So I used Mfgtool to program the nand in the recovery mode via the usb port. It was  successful, see the last fw messages form the console

 

...

UTP: received command '$ umount /mnt/ubi0'

UTP: sending Busy

UTP: executing "umount /mnt/ubi0"

UBIFS: un-mount UBI device 0, volume 0

UTP: sending Success

utp_poll: pass returned.

UTP: received command '$ echo Update Complete!'

UTP: sending Busy

UTP: executing "echo Update Complete!"

Update Complete!

UTP: sending Success

utp_poll: pass returned.

g_file_storage gadget: high speed config #1

 

 

All the images and sb files were created by "ltib --selectype" to select the type to build updater_ivt.sb for the mfgtool firmware.

Then I unplugged the usb port, reset the board. It did start booting from nand. But it stopped and never showed the login prompt. I attached the log file. Can anyone help and tell me what I have done wrong?

 

I have some other questions:

1) does the imx28_ivt_linux.sb include the uImage? I haven't seen uImage file being sent to the nand flash by the Mfgtool.

2) Should I still see "Starting utp" (see the log file) when booting from nand?

3) When ltib builds updater_ivt.sb, does it build the kernel/rootfs normally or in a reduced form?

 

Thanks in advance

As for the questions :

1)
> does the imx28_ivt_linux.sb include the uImage?

No. The kernel may be loaded by internal ROM.

3)
> When ltib builds updater_ivt.sb, does it build the kernel/rootfs normally or in a reduced form?


Special (ram fs based) form.

Hi Liu,

are you sure your kernel command line is correct? If I've well understood your problem, I think you can see i.MX28_Linux_BSP_UG (from L2.6.35_10.12.01_SDK_docs) paragraph 5.1.1.1: you can see which is the Linux command line for NAND boot.

In LTIB in "package list" you have 4 command line to set: I always the same command line to all lines.

Be sure complile your image explicitly with

./ltib -p boot_stream.spec -f

all times you change command line.

Regards

Emanuele
