Android KK 4.4.2 on IMX6Q Sabresd Board Testing Problem (Ubuntu 14.04)

cliffchen — Mon, 10 Nov 2014 02:58:06 GMT

Dear All,

I have been testing Android KK 4.4.2 on iMX6Q Sabresd board under Ubuntu 14.04 recently and have found a NFS boot problem describe below:

1). With Freescale prebuilt images, all SD boot, eMMC boot and NFS boot are working without problem. The Android desktop is entered and I can play around with USB mouse.

2). Then I tried to build new images by my working environment with the default configuration.

But this time, only SD boot and eMMC boot work. The NFS boot was failure as console log attached.

By hte way, in my NFS boot test, I have modified init.rc and init.freescale.rc as mentioned in 'Android_User's_Guide.pdf'.

3). Finally, I tried to use the 'rootfs' of Freescale prebuilt image with my own 'uImage'. And it works magically.

4). The NFS boot environment in the u-boot & in the Ubuntu host are both verified by prebuilt NFS image as describe.

I guess there are some configurations in my image made different from Freescale prebuilt image.

Would anyone can give some advices/hints on how to debug this problem?

Many thanks for your help in advance.
