status of flash_v2 branch?

status of flash_v2 branch?

[Jani Monoses]

Hello

Andrew, Bart, could one of you describe shortly what the current state of the flash v2 
work is?
I am considerig using it along with Savin's dataflash driver, as well as writing a lpc2xxx 
flash driver for the v2 API.
I checked out the branch but it seems it is not in sync with CVS head, some redboot and 
flash/io changes in HEAD which could be relevant to it are not merged.

Also this update
http://ecos.sourceware.org/ml/ecos-patches/2004-10/msg00000.html
is somewhat different from what is in CVS flash_v2.

thanks
Jani

It basically works. Bart once said Jifl had some fixes but i cannot
remember if they ever got merged in. We are working on the assumption
that eCos 3.0 will have it merged in. Until then its bit rotting in
the branch.

There has been no attempt to keep it in sync with HEAD. You might want
to try to merge the branch into the trunk for everything except
io/flash. I suggest you just use io/flash directly from the branch. Or
you could try merging the HEAD into the branch and see what happens.

What ever way you go, it would be nice to hear the results...

The dataflash all gets a bit messy because it needs the SPI code which
Bart did not contribute until after the flash_v2 branch. So when i did
compile tests for Savin's contribution i had some parts of the tree
from the trunk and some parts from the branch.

Basically, sorting this out has been defered until we start getting
3.0 together.
