Hello, using this build:
http://processors.wiki.ti.com/index.php/TI-Android-JB-4.1.2-DevKit-4.0.1_DeveloperGuide
By default the memory is configured to 256mb. Our board has 2GB installed, but the system is only set up to use 256mb. How can I increase this?
I have changed the boot argument in uEnv.txt, but I believe there is more configuration to do. Can anyone advise me where to make the changes?
Many thanks!
Moving this to the Android forum.
Hi Richard,
In order to support more memory, you indeed need to change the boot command parameter, but you also need to modify u-boot to configure the emif.
In u-boot/board/ti/a335x/board.c there are some emif configuration for different boards and memory that you can use as examples.
You may also need to change include/configs/am335x_evm.h and arch/arm/cpu/armv7/am33xx/emif4.c for number of memory bank and bank size.
Hi Richard,
In discussion with your colleague Michael it seems tht you are still having some issues in getting the additional memory recogines by the platform. As suggested would it be feasible for you to post a boot log showing the kernel command line config and console output together with your intended memory map - is this contiguous?
With the correct EMIF setup u-boot memtest should be able to exercise the expanded memory region fully. A kernel argument such as 'mem=2048M' should then be sufficient to make this available to the Android platform.
For the purposes of this thread the EMIF settings that you are using and sent me are below:

Also for completeness and context Michael stated that you are using the version of u-boot from this link and I appreciate that it would be very difficult for you to move to a later version of u-boot at this stage of development:

Hi Garry,
So far I've made the following modifications to increase to 512mb, please see the added lines. Our DDR3 uses banks of 128mb.

Hi Richard,
in order to help us understand this crash, could you perform the following tests and let us know how it behaves:
1) boot with the mem=128 command line argument
2) from u-boot test the memory using the u-boot test command (if available) or at least trying to read write some value manually using mm and md.
Hi All,
This turned out to be an issue with hardware, but many thanks for your help, I'm sure it will help someone else in future.
