[ECOS] newbie with a board

[ECOS] newbie with a board

[Abrar H Hazarika]

hi all,

I am very new to this field. We are asked to work with ecos on a board which
has a Texas Inst. TL16C452FN chip on board. The datasheet says it is a UART
chip. I am not sure about it being a microprocessor. Is it possible to port
ECOS to this chip?


Does anybody have any prior experience who might want to share with me.

thanks

[ECOS] Shell on starup

[Elton]

Hi,

I want to put a shell as my startu application when the eCos image,(with
kernel) is built,
From the eCos packages , I couldn't find the  option for sa shell,
Can any one tell me how to do it?

A UART is just a dumb I/O chip :-). There should be some other part on the 
board which is the microprocessor. Generally looking for the biggest one 
tends to work ;).

The microprocessor as "P51XAG30JBA". It is philips make and the docs say
it's discontinued to make way for P51XAG30KBA. Belongs to the 80C51 class of
16 bit micro controller and XA (eXtended Architecture) with 512 bytes of
onchip RAM, 2 UART's.
The ecos docs didn't mention porting to any such arch. Or is this same as
one of the already ported arch's.

Is anyone familiar with porting of ecos to XA?

thanks

If it's a C51, it is certainly not supported by eCos and I am affraid
that it won't even be possible to port eCos to it. As far as I know,
eCos has not (yet) been ported to any 8-bit micro so far. Most important
reason being that you 'd have to start porting the GNU compiler to it
first. And that's still considered to be _hard_ for anything else but 32
or 64 bit architectures.

IIRC, uC/OS2 can has been ported to the C51 family.

I know that there isn't any chance, but wanted to make sure that you meant
16 bit micro and not 8 bit as mentioned.

I meant 8 bit (any C51 I ever worked with was 8 bit anyway. Don't know
if there are 16-bit variants). Doesn't make much of a difference though,
there's no port of GCC for the C51 family.

So, I can't get eCos up for my PDP-11's... then there's the Z80,
which I had totoally forgotten about for the most part, and yet
about a month ago someone asked for a quote which involved
a Z80 20-years-later-part which have a variety of I/O devices
and a chip cost of under $5 US... there was a kernel and an
TCP/IP stack available... pretty much shocked me out of
my complacient ideas about how long processors can live.

:-) We don't have any religious objection to supporting non-GCC ports, but 
obviously at this point it's pretty difficult and with requirements like 
C++ constructor priority ordering, or even just requiring arbitary 
sections which not many other executable formats than ELF can do, there 
are going to be difficulties.
