Hi Roy,
I think so. SMP863X is an highly integrated System on Chip. You need
their kernel patch for IDE driver,PCI driver,Serial port driver, Flash
interface driver, Network interface driver and USB driver.
All SMP863X set-top box vendors are suppose to release the kernel
source with this patch according to GPLv2.
Despite the kernel patch, you can have your own cross tool to build
any software on it. Sigma Designs SDK is base on buildroot, and I did
successfully build opens source software on it using OpenEmbedded, base
on WRT54 branch.
However, any video related operation really need their closed source
SDK.

Dear David,
I am a developer on Sigma Designs SMP8634 platform. Technically
speaking, it doesn't run uCLinux as it has MMU. It runs a main line
kernel with Sigma Designs' patch.
do you mean that it will be impossible for me to run uCLinux without
sigmadesigns SDK?
or can i use buildroot or OpenEmbedded to compile?

don't know anything about it. I told them they have to

license and they
may consider drops Linux support...
Well...
Relax, thats not going to happen. Linus dont want gpl v3 for
the kernel.
I dont want to buy boxes like the Tivo though.
So far it is. But how about Samba NTFS-3g? Any component we
used in
our product changes to GPLv3 would give us a headache.
Sigma Designs 863X platform requires the kernel image to be
signed so
that the bootloader boots it. I foresee this conflict of GPLv3
and
signed kernel. I think I could not disclose the key for
signing a kernel
to end users so that they can build their kernel. I may need
to build a
signed 2nd stage bootloader to boot unsigned kernel image. It
will slow
down the boot process in turn.
I also afraid that I breaks the license agreement with Sigma
Designs and
with Microsoft, for WMV DRM, if I let users run their own
kernel on the
product.
