debug problemsss

[teo_icKs <teo_icKs@ooooo.net>]

Hi, I'm new in this mailing list ...  I'm using ELKS kernel in a
embedded
system with
an AT architetture,
Elan SC400 processor,
2mb RAM, - 640KB real, 1MB extended
2mb flash eprom as HD
Floppy 1.44 which now I'm using to boot kernel Image
A20 gate for Extended Memory
XT keyb on elan controller
two serial port

For use 1.0.1 kernel in this system I added code for implement keyboard
in SC400 Microcontroller (change an address for the data-register keyb
from original code);

Kernel now, seems run correctly but only when mounts the  root
<sibo image>.

When I want to use the other image, the init process return an error
when reading the config text file. Sometimes, it return also an out of
space memory error!

Is the standard init process using the entire amount of memory to run
(2MB)?

I think it can be a problem due of my HW!!!!.....

With the <sibo root image>, when I run application more larger than
os utilities, system crash as before I explain.

For me the problem is on the A20 gate handling. I try to initialize
it in assembly code as there's in the 2.2.20 linux official kernel but
nothing change.

In my embedded system are there any difference (memory mapping ecc.)
from standard implementation of ELKS??
In boot kernel retrieve >  ... 637 Kb base memory and 1024Kb extended
memory....

How do I debug this kernel on my system? is there any standard solution
or must I to insert puts() for everywhere?

If anyone has a good idea, please send it to list........    thanx at
all!
