Hi all,
Can anyone guide me in the best way to set up a FTP server on davinci
EVM that can access files on the Hard drive or Compact Flash.
Kind regards
James McGloin

Just curious, does encode+decode work for you?

I am seeing a similiar crash. But I'm curious how you'v deduced that
it's triggered by an ioctl? This trace shows a crash in the EMAC
driver, which took an interrupt during some NFS stack activity.

I'm not sure what you mean here. I'm not ready to integrate this VPFE
into the git tree yet until I better understand the other kernel
changes. Also, the generic changes to the video-buf layer are not quite
right, and I need to work on something that's more acceptable upstream.
One other thing, can you tell me what problem your ioremap.c change was
meant to fix?
Thanks,
Kevin

Hi,
The DVEVM board comes with a HUGE filesystem on the 2.5” hard drive. On boot
up, the Linux kernel mounts the partition
(/dev/hda1) to be used as the root filesystem. The filesystem is 1.9GB! This
is good for development purposes but when we have
our custom board, we will only have a small flash memory to store the
filesystem. Do anyone have instructions on how to create
small footprint filesystem (<16Mb)? I was planning to do a top-down approach
of eliminating all the files/directories
(/opt/mv_pro_4.0/montavista/pro/devkit/arm/v5t_le/target) I don’t need until I
get it to a manageable filesystem but I’m not sure
what are needed and what aren’t. Has anyone done this and have a recommendation?
Also, the current “top” (procps) utility on the board is version 3.2.5; it
doesn’t support displaying individual threads of a process;
it only shows info about a process as a whole but not the thread. Version
3.2.6 has that capability; does anyone know how we
can get that version?
Thank!
Regards,
Andy

Some places to start...
There are two ways to do this. Start from the existing and pick away
packages until you have what you want. Or, start from
busybox/buildroot and add packages until you have what you want. The
latter is the best way to get the smallest rootfs, but if you have 16M,
you may be able to get there using the former.
If you have the MontaVista tools, DevRocket includes a tool called
Platform Image builder which allows you to select build your own rootfs,
and it will handle all inter-package dependencies for you.

Just download it and compile it. :) The development rootfs that ships
with the DVEVM/DVSDK has the native compilers/linkers etc. to compile
natively.

The git kernel does not yet have a working MMC driver. It does not
compile due to the use of an obsoleted API.
I'm curious how you got the davinci_mmc module for the git kernel?

Take a look at OpenEmbedded. (http://www.openembedded.org) I use it to
make custom images for the OSK board. If I can get a Davinci board and
some time, I plan on adding support for Davinci based systems.
