[microblaze-uclinux] Reg uclinux/microblaze on ml310 (flash woes)

["Lakshmi Narasimhan. S" <sulakshm@xxxxxxxxxxxxxxxxxxxx>]

Hello John,
I went through the manual you prescribed and was able to successfully
build a uclinux hardware.  The manual was excellent read.

I would also like a few more inputs, mainly because of the
different board version am using (ml310).

1) I do not find FLASH option with the initial projects.

   From the ml310 board manuals, I see that a System ACE CF controller
   can be used to faciliate general-use, non-volatile storage.
   The System ACE controller provides an MPU interface for allowing
   a microprocessor to access the compactFlash memory and it
   is 512MB, a lotta space. Now I have this in my configuration,
   but it doesnt show up as an option with Flash (Sw settings ->
Library OS parameters).

   So, I then used Add/edit cores to add opb_emc, but I am stuck with
   the configuration. I am not able to find external pins that I need
   to connect to from my fpga opb_emc to the compact flash!!!
   Does anyone have any success configuring ml310 to access compact
flash with opb_emc? can you share the config files.. .mhs and .ucf
for the same?


And also, for getting that uclinux option, I had to copy
uclinux_v1_00_a/c to <edk_install_dir>/sw/lib/bsp for the option
to throw up with software settings. And it shows up.

And I cannot build a uclinux until I have a opb_emc configured
successfully. (as build fails with libraries, doesnt accepting "none"
as an option with Library OS parameters -> Flash -> "none").

Sincerely
LN
