[U-Boot] Urgent : Cortex A9 quad core versatile express ca9x4_ct_vxp support in U-Boot..

[Sandeep Kumar]

Hi all,

I am trying to use U-Boot for a custom board based on cortex A9 quad
core versatile express board. I saw that the support is already added
for that board but i am not able to find out the DDR initialization code
anywhere before using the stack. In fact i didn't find the DDR
initialization code anywhere for this board. This board also comes along
with a CLCD (color LCD) controller which is also not initialized
anywhere for this board. Is the support for this board is tested as
without initializing the DDR how the code relocation and execution from
DDR is possible.

Any kind of pointers will be very helpful.

(sorry Sandeep for the double mail; I guess that's what I get by 
answering e-mail before the morning coffee starts having an effect.)

There was no need to repeat your message at such a short interval of two 
days.

As for your board, did you try U-Boot with it or did you just look for 
code? This is not clear from what you write.

Also, did you think of asking the official board maintainer as 
identified from the MAINTAINERS file at the root of the U-Boot code base?

I personally do not know the board or the vexpress, but it might well be 
that DDR configuration is done through a configuration block added by 
mkimage -- at least, I can see that mkimage is built by a ./MAKEALL 
ca9x4_ct_vxp.

Amicalement,

Sorry for not responding sooner.

Currently the DDR setup is handled by the ARM boot monitor code
and u-boot runs as the 2nd stage bootloader. So DDR setup is
not done in u-boot.

Also, the CLCD is not setup in u-boot.

Hi Matt,

We are in a process of developing a SoC around cortex a9 quad core
versatile express. For that we made changes in the U-Boot. Is there any
way (like any simulator/emulator which supports this board) to validate
the changes before getting the arm board itself.

Any kind of help is highly appreciated.

QEMU supports supports a few ARM versatile boards.

Peter Maydell has been developing QEMU support for the
Versatile Express. Here is a link to some of the work
he has done:

https://wiki.linaro.org/PeterMaydell/QemuVersatileExpress

It looks like the instructions are for kernel testing.
So you may have to spend some time figuring out bootloader
support, but I suppose it would be similar.
