hi,
You may want to use a binary editor to look at the resulting binary
image and make sure it follows the required format=3D20
-hi i tried using od(octal dump) to see if i can make out some thing =3D
from the
image. but i could not follow much as i am trying the od for the first =
=3D
time.=3D20
and that the CRC is
indeed what was computed in the first link step.
- can you give me little more info about what exactly needs to be =3D
checked and
how it could be done?
i still doubt the image creation as the one which is falty. but done =3D
know
where it could be. i am totally stuck now.
thanks,
regards,
/Ravi kumar

OK - I see now it is a lot more involved than I initially thought.

hi,
thanks for reply.
i tried what ever you have suggested. but without any success.=20
I think you should be using 'flashload' (p 4-17 of Evaluator E7T User
Guide), not 'flashwrite'. As far as I can tell, 'flashwrite' is a 'raw'
write to the flash, i.e. copies RAM to flash, without putting any module
header on.
i tried using the flashload but it is not giving any success.
According to p 4-29 of Evaluator E7T User Guide, I don't think you need =
to
include a module header in your code; this will be added by the =
bootstrap
loader. This may well confuse the module management software.
i dont think that BSL will add any thing to our application. because =
when
building the redboot the module header is explicitly added(
packages/hal/arm/e7t/current/cdl/hal_arm_e7t.cdl). and i am able to =
build the
redboot and put it in the flash and see that it is listed when i say
'rommodules'. what really wonder is if it is possible to add the module
header for the redboot why cant it be added for any other application =
and
make it work similarly. that is why i still doubt that i am missing in =
adding
the modul header. is it possible to look at the make file and the module
header file and tell me if i am missing anything.
thanks and regards,
/Ravi kumar.
