Hi,
I m working on armboot bootloader. I m trying to access the large
page(2112 bytes) NAND Flash from the bootloader. I had succeeded in
writing
a small pattern to test erase, write and read the flash. I dont have
any
idea abt checking ECC for the same. If anyone have worked on the same
ie.,
the modification of the code to support large page nand flash, please
give
me some suggestions. FYI my present code supports NAND flash woth page
size
528 bytes.
I would be very grateful if any of you could suggest me as of where
exactly I m going wrong?

1. wrong group
2. you should be able to find databooks for the flash memory [if not
you should buy from a better company]
3. You didn't post code for us to review [in the off chance someone
here knows]
4. It's wednesday.
5. You're really in the wrong group.

[1] You haven't read the device spec sheet carefully enough.
[2] You haven't said what problem you're experiencing.
[3] You haven't posted any C code so that anyone could provide any
kind of help.
[4] You're (probably) posting to the wrong newsgroup. This ng
discusses C programming.
Other than for those minor details, you're doing fine. :-)

One wrong thing is posting to this newsgroup. Please try in
comp.arch.embed ded (Added to groups list.)
You also need to supply more information, otherwise nobody will be
able to help you.
You say "modificati on of the code to support..."
How can anybody guess what is the original code and what was modified?
The same goes for the hardware. Which type of flash memory chip, under
what platform, (CPU? development board? custom hardware?).
What development tools you are using, etc.

Look at the u-boot project, you can find source there that handles the ECC
on NAND flash.
Sorry about the late response. I've been busy...and I didn't even know about
this newsgroup until today.

Hi,
On my ASPx.NET page I have quite a lot of controls, so it takes a little
time to build it.
Because of this when you click on a button, the page is redrawn and whatever
the action was, the page is changed.
But most of the time, not always strangely enough, there is a white page
when the old page (the page is in black background) is discarded and the new
page is loaded.
So everytime one clicks on a button, you'll get a white flash on...

Hi,
I'm modifying a template (flash menu with html pages), when you click on the flash menu (about us for example) the corresponding html page is displayed, and the "about us" flash menu is highlighted.

The problem is that they didn't have a link to the home page, so I modified one of the already existing menu and put "home...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
