Linux Gaining Support In Embedded Systems (TechWeb)
(Posted Dec 11, 2003 19:03 UTC (Thu) by erich) (Post reply)

Typical "embedded" Linux systems are kind of "homegrown"... the one
i've seen - the SDK of Intersil for the ISL3893, which is - although
mostly GPL - NOT publicly available - is based upon a fork of uclinux
around late 1998.
It sucks. They hacked their logging into every application, disabled
features and made many many mistakes (wrong #ifdefs and such) while
doing that. Instead of providing proper patches they ship ancient
versions...
They also did not push back their changes into uclinux, so they could
be intergrated into future releases (such as hardware information that
uclinux could build out-of-the-box for that hardware)
And zcom, taiwanese manufcaturer further modified the kernel without
releasing source...
Manufacturers suck. They havn't understand Open Source, and that is why
they have all these problems.

Why Intersil does not give their modifications to the kernel and BSDL
files public?
