i.MX6q SabreSDB: Android JB 4.3 via NFS issue

[Igor]

Hello folks,

I looked for some solutions in other threads but I have not found appropriate answers.

My goal is to boot Android 4.3 OS via TFTP and NFS but unfortunately I can't do that.

Target device is a MX6Q SabreSD Board.

I think my Ubuntu server (version: 12.04 LTS 64bit) is properly configured:

1) I have installed the software required for the TFTP and NFS servers.

2) I have created one directory /android_fs/nfs and I copied Freescale's android root directory contains into that nfs directory.

Further I have copied system directory into nfs/system.

3) I add following line at the end of /etc/exports file:

/android_fs/nfs *(rw,no_subtree_check,async,no_root_squash,insecure)

4) I modified nfs folder permissions:

sudo chmod 777 -R /android_fs/nfs

5)I started Xinetd and NFS server:

sudo /etc/init.d/xinetd restart

sudo /etc/init.d/nfs-kernel-server restart

6) Target Device is connected directly to the Ubuntu server via ethernet adapter.

In the attached files it is possible to see "uboot-vars" and "booting-up prints" of the SabreSDB device.

Why does the system hang at "freeing init memory" point?

How do I have to modify "init.rc" and "init.freescale.rc" files for booting Android 4.3 via NFS properly? Are Freescale NFS release files "ready to use"?

I wish to specify I'm using Freescale release files (Android root system NFS, uImage and uboot_6q.bin)

Thank you in advance,

Igor Ferrara

Hi Igor, 

Can you give the steps to set up nfs server? We need help right now. What exactly was the fix. Which permissions we need to set?

Regards,

Hello,

I solved that issue.

The problem was with permissions of "nfs" folder in the Ubuntu NFS-Server: they were not set in the correct manner.

I had to compare the permissions of the Android file system released by Freescale with the one created by me and modify them where necessary.

I hope this will be useful.
