Am335x EVM with ramfs

Hi Sreenivas,

First of all, verify that the /sbin/init binary exists inside the root file system you used to create the ramfs.

Did you read the kernel documentation as suggested by the error log? If not, please do and try to narrow down the possibilities for the error:

<linux_kernel_dir>/Documentation/init.txt and <linux_kernel_dir>/Documentation/initrd.txt

Best regards,
Miroslav

Hi,

Kernel command line: console=ttyO0,115200n8 root=/dev/ram0 rw initrd=0x80100000,58M rootfstype=ramfs init=/sbin/init

I would like to suggest to use less than 20MB for RAM fs for first time, If you get succeed then try with bigger fs.

Please refer the TI wiki.

Hi Miroslav,

yes I have verified,init file and it was in "/sbin" 

Hi Sreenivas,

Are you able to solve the problem?

Have you referred the TI wiki ?

Hi Titus S,

I have used the same TI wiki to create the ramfs, but the problem is that the base file system provided with AM335x SDK 7.0 was nearly 60 MB, with that there are some more files need to be added for my requirement, so the file system cannot be smaller that that. 

Hi,

[    2.340570] VFS: Mounted root (ramfs filesystem) on device 0:13.
[    2.347131] devtmpfs: error mounting -2

Have you enabled "devtmpfs" support in kernel ?

Please check the above error from devtmpfs. (No such a file or directory)

Could you please share your complete bootup log.

Hi Titus S,

I am using pre-build Linux image, i dint do any changes to that, i have attached the total log, please find it in the attachments.5875.log.txt
