EagleTree errors in Ubuntu 14.0

Hi, I'm interested in EagleTree project. I got many errors when try to build the project according to the tutorial given in the https://github.com/ClydeProjects/EagleTree/wiki.

Assertion `false' failed

I have this error when trying to run my code with FTL_DESIGN = 0 and FTL_DESIGN=3.

You are trying to read logical address 318838, but this address does not have a corresponding physical page in the mapping table.
It is most likely that nothing has been written to this address so far.
demo: FTLs/page_ftl.cpp:112: virtual void ssd::FtlImpl_Page::set_read_address(ssd::Event&) const: Assertion `false' failed.
can you help me to solve this issue?

what is FAST FTL?

I am reading the code of FTL section.

I guess DFTL means Demand FTL(if i am right).

But what is FAST? What does it stand for?

Thanks!

Thanks.

Tutorial of EagleTree ?

Hi Niv,
First, I would like to thank you for your efforts on this project.
Can you provide tutorials on eagletree?
I hope to learn more and understand eagletree in depth.
In addition, there are three links in the REDEME.txt file that cannot be accessed.

the block write method

Hi
I am reading the code of this project.

I do not quite understand this line in block.cpp:

enum status Block::write(Event &event)
{
if (event.get_address().page > 0 && data[event.get_address().page - 1].get_state() == EMPTY) {
printf("\n");
event.print();
assert(data[event.get_address().page - 1].get_state() != EMPTY);
}
enum status ret = data[event.get_address().page]._write(event);
pages_valid++;
return ret;
}

Why the assertion is "the state is not EMPTY"?

I think it should be EMPTY.

I am very confused.

The flow of wear leveling process

Hi there,
First, I would like to thank you for your efforts on this project.
I was wondering what is the exact course of wear leveling process?
I have read the wear_leveling_strategy.cpp and I can understand all the functions. But I want to know the exact flow of wear leveling process. when and where it invoked? what and where it do?

Bests.
