AOSP Building BOOTLOADER for Manta board

[Tom Johnson]

Can some one point me in the right direction to be able to get and build bootloader code for manta board?

Thanks,
Tom

Bootloaders aren't part of Android (they live 2 levels below), and there's never been an Open Source bootloader for any of the devices that have been supported in AOSP.

Thanks JBQ!  OK so basically what if I wanted to create a bootloader for manta, how would I go about doing that. I mean you guys at Google have it for Manta (nexus 10 devices) . Did you create from scratch or is this like U-boot code that has been modified to work with Manta. I just want to be able to get some bootloader code , modify and build it with the AOSP project and create a bootloader.img.  Is there some links you can point me in the right direction of where to start.

Thanks,
Tom

We don't build bootloaders at Google, we always get them as binary drops from the OEMs. This is a far lower level than Android.

OK Thanks JBQ....  

Would you have any possible links that I could do research to develop my own for this type of board?  

The Nexus 10 device that we have is rather easy to unlock, so I would like to modify the boot loader to make it locked and  not easy to get into by just pressing the power key and volume keys. Is there a way to make it so that it would go into recovery mode when you did that or would that be part of boot loader code to be able to do that?

Thanks,
Tom

I don't know where you'd start to do something like that, sorry, I'm a software guy, not a hardware guy. The code that controls what happens when booting with the volume keys pressed is all in the bootloader.
