Another try.

The log filled with error messages about how it was too tiny, but it still mounted, contained valid-looking files, and let me edit. The size wasn't off by a factor of a thousand this time so this at least stands a better chance of working than my last try. Good luck to you.

Programming flash...

---------- Post updated at 05:03 PM ---------- Previous update was at 04:16 PM ----------

Your file looks like this:


First part is modified Config.ini but not packed.
Second one is Config.ini in original version.

I programmed flash with second one, and unit is still AMER. So there is no change.

Now, I will program it with first part.
Is it ok that meta data is unpacked?

I have no idea, but jffs2 is pretty strange baffling diabolical as filesystems go. I wouldn't necessarily expect a sector to change just because I modified its contents. jffs2 avoids writing to the same sectors over and over by spreading out over fresh, empty ones. This also makes it very hard to tell how much space is actually free in a jffs2 system since one block might have n slightly-updated duplicates. Eventually it decides enough is enough and consolidates itself, but only when it absolutely needs to.

Try the data I actually gave you instead, all of it Smilie

Ok... Programming flash with "ASCII" Config.ini Smilie

---------- Post updated at 05:37 PM ---------- Previous update was at 05:17 PM ----------

Unit says: " Unable to open Config.ini" Smilie
So, ASCII version does not work.

Please, explain to me how it works.
You mount original Config.ini as new/virtual drive in your system.
When you access to this drive you can see all 3 files.
You can edit it.
After edit, you make image of this drive.
But image does not contains any changes.
Am I right?

Afraid of that... At least we know we're working in the right place, though.

I'll have to think on this.

It could be the ECC, you know.

Tomorrow, I can try to fill ECC blocks with 0xFF and I will program flash with original Config.ini. We will see what unit will say.
