[ECOS] how to booting the redboot on VMware

[ECOS] how to booting the redboot on VMware

[xiaolu zhao]

Hi,
I want to try the application examples in the 12th chapter of
"Embedded software development with eCOS". I want to use a virtual
machine on VMware software as my target. I already successfully
install redboot in a virtual machine and see the RedBoot prompt.

But when I try to booting redboot, in the step 10 and 11 which tests
if the host and target connetec well. I found I the host and target
are not connected.

I used my notebook as the host. And I tried the HyperTerminal on the
host to connect the target. Becuase the notebook has no serail port,
so I choose  TCP/IP instead of serial port. And I use the IP address
of the redboot image as the "host address". But the redboot can not be
conneted. Is there something wrong of my operation?

Do you ever meet this problem? And would you like to give some advice
how to solve it?

Thank you so much in advance!

Tina

[ECOS]: Free BSD stack -

[Alok Singh]

Hi,
I'm doing an ECOS port of my application software. I'm using Free BSD
stack as my TCP/IP stack.  I'm seeing one strange thing that packets
coming out of stack are not in network byte order. 

The packets are coming out of the stack in little endian format. See the
logs below for an ARP request packet(dumping byte by byte). Can you
think why this might be happening?  Network stack always sends the
packet out in network byte order, that is big-endian.

Re: [ECOS] how to booting the redboot on VMware

[xiaolu zhao]

Thank you for your advice.  Currently I used a software which can
provide virtual serial port. Thus the Host can communicate with VMware
and I can run the hello world on the virtual machine through the
serial port.

Can I ask you one more question?

Because I just start to learn the software development on a RTOS, so I
have no idea about what is the application software on a RTOS looks
like. I only have some experience  in embedded software development
without a RTOS. Do you know where I can find some application example
on eCos or any other RTOS(more complicated than the examples in the
ecos source code)?

Thank you in advance!

in ecos there is no very strict distinction between app and 
kernel...actually the distinction between os and app in embedded system is 
not as obivious as in other enviorment
I don't know what kind of app you are looking for, maybe minigui is a good 
choice for u , however, i think ecos itself is really worth studying 
intensively

Re: [ECOS] how to booting the redboot on VMware

[xiaolu zhao]

Thank you for your anwser.

Maybe I will ask a silly question. In a normal C program, the
execution of the program start from the beginning of the main
function. In the folder  "\packages\kernel\v2_0\tests" i saw there are
some test files. ( I don't know if all these files can be used as
individual application examples ?). In these files, I can not see the
main( ) functions. They only have cyg_start( ). So I am confused where
the application program start from, if they have no main( ) functions.
And who invoke the cyg_start( )function?

Can you help me with these questions? Thank you so much!!

The eCos documentation is your friend - all of this is explained there.
  http://ecos.sourceware.org/docs-latest/

eCos provides very complete control over how the application starts.
cyg_start() is the actual starting point for application code.  It
normally calls cyg_user_start(), then starts the scheduler.  The default
version of cyg_user_start() will create a thread environment for running
'main()'.

Look at the examples to see different ways of handling this.  Having
your application start as 'main()' is the simplest, but certainly not
the only choice.

Also, eCos 2.0 is terribly old.  Given that you are just starting out,
it would be wise to work with the latest (CVS) code.
