amol chor said:i can't able to create minimal file system for my board which will take via tftp !!
how to create image file for am572x board which will take minimal file system from initramfs via TFTP server???
Upon looking into this issue further, I think this is your primary issue?
If so, this is a generic Linux question and there is nothing that needs to be done specifically for TI platforms; it is all generic Linux. There are several good guides on the web to help with creating an initramfs in Linux.
The base filesystem provided with the SDK in sdk/filesystem may be a good candidate as a starting point. You'll need to change the init to point to systemd, which is a documented requirement for setting up an initramfs.
From the log, it looks like you've possibly done something with this, but I don't know what FS you started with.
Can you try the base FS, make the changes required, and see if that works for you?
Thanks, Ron
