Hi CAlex,


Are you mentioned the part where you are trying to build the u-boot?

After you have obtained and built your ghrd, you will proceed to the next step to consider consider u-boot

Referring to this document on the part where you are going to build u-boot:

https://www.rocketboards.org/foswiki/Documentation/SoCEDS

Note that you will need the embedded_command_shell.sh to perform the build.


Thanks.

Regards,

Aik Eu

    Yes I build the u-boot , more accurate, the u-boot-spl from my GHRD.

    Since I'm working on bare metal, I don't need u-boot.

    As for preloader.ds part, it is from the GHRD itself.

    The Linaro keep failing so I start to use ARMCC

    Another wield issue occurred:

    when mainully load the spl ,downloaded the axf file and start from the entry point,

    it started at S:FFFF0000 where is the on chip RAM location.

    But in the guide it should start at S:02000000 where the SDRAM at.

    When I used the scatter pointed to 0x02000000, the program made an error from 0xFFFF0000.

    So my question is how can I start from sdram?

    Here is the reference PDF I followed:
