am335x filesystem UBIFS

Hi Bernie,

I think you should ask this question to the Webmin community support: http://www.webmin.com/community.html

Hi Biser

I make a UBIFS format of ubuntu filesystem. When I use SD boot it works very well  and has prompt of login.

But when I boot from NAND, it hangs that message of login is not appear. These are my log from nand below

ubiattach -p /dev/mtd7

ubimkvol /dev/ubi0 -N rootfs -s 200MiB

ubiupdatevol /dev/ubi0_0 /ubifs.img

U-Boot# nand read 0x82000000 0x280000 0x500000;bootm 0x82000000 

ps. Our nand flash use 4K page size

Any method  can I try?

Thank you

Hi Ivan

Our target filesystem of Ubuntu of UBIFS is made by package of apt-get install mtd-utils. 

1 Did you mean that I need complile mtd-utils and execute mkfs.ubifs  to make UBIFS image on target?

2 I try to use filesystem of XXXbase.tar.gz in SDK6 and use "flash_erase /dev/mtd1 0 0 " in user space. 

   why did the error message "permission denied" appear? 

Thank you.

Hi all

We can login from arago-base-tisdk-image-am335x-evm.tar.gz

I have referenced the wiki and built mtd-utils source code for ubuntu that the result is the same....

ubuntu can't login, we need use ubuntu.

Thank you.

Bernie,

we support in our forums the Linux versions from following page: http://www.ti.com/tool/linuxezsdk-sitara?keyMatch=sdk&tisearch=Search-EN

Hi TI

I have tried to flash TI Linux and  it can be booted from nand flash, but our customer want the distribution of ubuntu.

we found the problem point that is our am335x custom board must to detect the mmc 0 (SD card) so ubuntu filesystem 

can be login by nand flash, if we don't  insert the sd card, there are no login message appeared.

======================================================================================

Which parts that I can revise? kernel or hardware? I really need Ti support. Thank you.

Hi  TI

I have resolved this problem, thanks.
