Allwinner A20/A10 Android Custom ROM Update without FEL boot

[ஜெ மணிகண்டன்]

Hi,

  We are looking for ways to update the Andorid image in the Allwinner target platform with out using FEL mode .i.e just like how Samsung phone allows us to update the images with out any externel process using OTA.

  While we see a lot of methods to update images using FEL mode, is there any ready made solution to update u-boot, kernel, android and file systems without FEL boot approch. Can it be done using a simple script from the Android/Uboot modes to update the above.

That's really more an android specific question. CM and replicant can be
updated OTA quite easily, it downloads an image, it reboots to recovery
mode and reflashes the kernel, CWM and CM itself.

Once you load a linux kernel, you can do anything you could normally. In
recovery mode you load a kernel + initramfs, so nothing is mounted. How
would it be different than installing any custom rom via CWM etc before.

Replacing the bootloader is irrelevant, you can't really rebuild it
anyway, and why would you want to. Ours can't even boot from nand yet,
so moot in that regard.

replacing the nand based u-boot is easy, since you can mount, replace,
remount any file on nanda without much fuss whilst running android even.

So what is your question really that's related to sunxi?
