Hellow all !
I am trying to port elks on to Blackfin DSP (21535).
I took the working sources form the elks site which worked on my 86 machine.
Can any one suggest me what are the exact issuues (problems) that comes into picture while porting.
i.e I want to know which parts of the code need to changed......
My present status of this project :
I compiled the C sources of elks with Blackfin compiler commenting out assembly part and trying to
port..

Hello from Gregg C Levine
Everything. ELKS is a x86 targeted project. As it happens, ELKS can not be
ported to that DSP with out major work. You are strongly suggested to
contact the company that makes the chip regarding a more suitable Real Time
kernel. Also please examine the archives of this group, as we went over this
subject, three times much earlier.

Hello Gregg C Levine and ALL !
I and my colleage only discussed this topic , 3 months earlier.
Now I am on this project...
So can u tell me which parts of the code need to be changed.I want to have minimal code to be booted first and later want to add one by one.
I want to make minimum kernel Image and bootit from the DSP . This is my first aim.
Thinking in this way Plz , suggest me the directories wise changes( like kernel / , fs , / arch/i86/kernel/ , arch/i86/mm/ ).
I am facing problems to understand all the code as i am new to this field.
Please Help me,
Thanks and Regards
Srinivas

Hello (again) from Gregg C Levine
I remember. And I also remember that the group told your colleage that ELKS
was, (still is), an x86 targeted OS. That unlike the actual Linux Kernel, it
wasn't portable. Oh it could be installed on a Psion, but not here. This DSP
does not use the x86 instruction set. Your ideas while lofty and good, don't
work. It would require a major rewrite of the entire kernel, and that's not
poissible, because it is an x86 targeted one. Your better off, investigating
my earlier advice, or even trying to port native Linux to it. Some related
processors are targets.

Major rewrite of the kernel? I'm not familiar with the DSP chip. But
major rewrite is probably never required. The rewrite will take place in
the assembly parts of the kernel and possibly in the memory manager of
the kernel.

Having worked with the blackFIN processor I can tell you that a major
re-write of the memory management model and many other parts of the kernel
would be required. uClinux would be a better kernel to work with or the
new Linux 2.6 kernel.
Srinivasa should contact the manufacturer (Analog Devices) as they once
claimed on their web-site that they were working on a version of Linux
for blackFIN.
