@candinico: I'm not sure I understand your last post.
If I do, though, I think you miss the point (or part of it): your issue here is that your boot-loader must recognize the partition first…

You still haven't clearly expressed what exactly you intend to store on a jffs2 fs.
Boot files? Personal persistent repository? Or both of those?

ok. i'm clarify :) i'm esotheric sometimes  :)

setup:

a) TinyCore 3.6 running on GEODE AMD ca 500MHZ RAM 256k
b) applications  : a MySQL engine , among others, with data in a PERSISTENT path ( in fact , on the support)

The problem is to ensure a filesystem and a storage type ( already solved) to store safe and fast the data of our application

First, I would drop TC 3.6 and move to current 4.7.7

TC 3.6? Wow! I'm not even sure anything I've written before actually applies to this TC…

Then search wiki for remastering with adding modules and add the jffs2 module.

Still I'm not convinced that SD card use really verifies need of jffs2 and all extra work. Embedded systems, and Raspberry Pi is fine with ext3/ext4 on SD card.

@bmarkus: I'm performing these days various benchmark about filesystems and SD and DOM on our systems, to discover the advantages of the different filesystems. I'm curious about your opinion on JFFS2 on SD cards: why the ext4/ext3 is best for you?
Do you have some "doc" to enforce this opinion?

Looks like you yourself have provided all proof ever needed about the advantage of compatibility since start of this thread which now reached Reply #23...

@tinypoodle  for the number of post, seems to be a flame :) I'm really interesting on advantages of a certain filesystem respect to another one. Suggestion from experiences? Related to tiny?

There is nothing TC specific, TC is just a LINUX. There are plenty of good articles on the file systems, use Google to search. At that phase it has nothing to do with Tiny Core.

Quote from articel you are referring:

Please, do not be confused by USB stick, MMC, SD, CompactFlash and other popular removable devices. Although they are also called "flash", they are not MTD devices. They are out of MTD subsystem's scope. Please, read this FAQ entry.

There is nothing to do with jffs2 when you have SD card, as it is the case here. Except very low end cards they have a built-in wear levelling mechanism, you do not need any special attention.
