Patch to change the Android boot storage from eMMC to SD on SABRE-SD board.

[AlanSouza]

The diff provided in the Android User Guide is not working to me. I'm trying to apply the patch but i keeps returning that **** Only garbage was found in the patch input. Where can I find the patch file?

Hello Alan,

Can you please tell me which Android are you building? and what are the steps listed to change the boot storage from eMMC to SD?

Well, seems like I was missing something applying the patch so I've modified the file /android_source_folder/device/fsl/sabresd_6dq/fstab.freescale manually and after compiling I could boot from SDCARD sucessfully.

Sorry for late reply. I just had the chance to test it.

I'm building the Android 4.4.2 kit kat. The steps are pretty simple. I just need to modify the file /android_source_folder/device/fsl/sabresd_6dq/fstab.freescale according to the diff provided in the Android User Guide. The diff looks like the lines below:

diff git a/sabresd_6dq/fstab.freescale b/sabresd_6dq/fstab.freescale

index c2b737a..d2e59a3 100644

I've created a file file.patch with this code and applied the patch from the folder /android_source_folder/device/fsl/ using #patch -p1 < /wherever_the_patch_file_is/file.patch. Looks like I'm missing something when trying to apply the patch.
