Cowon X5 w 240GB SSD - need help/advice with compiling

[Hogwash]

Hello all,

this is my first post, so again: hi folks !

I only recently successfully pimped my Cowon X5 60Gb with an 240GB SSD
http://www.mx-technology.com/en/product/ssd2.php?sid=5#fragment-13.
It is working ok so far, I just had two freezes (one while changing themes, the other while selecting a song) and when I chose a song it takes more than 10 seconds to load, so I guess I should do something to improve performance...

So here's my question(s):
1- Should I compile my own version of rockbox ?
2- What would be the benefit of that ? (As I understand it I compile on my computer, so how does that change the rockbox build on mx X5?)
3- Most important: What can I do to better implement the SSD into rockbox ?

I did find some hints in the forum on my topic, but most of it is rather outdated (poor old X5  ) so I thought it would be wise to start a new thread.
I simply formatted the SSD to fat32, installed with rockbox-utility and it worked right away, so I guess it's just some small tweaks that have to be done, right ?

Hach - I am so excited: installed the SSD, found a 1300mAh battery that fits my X5 (but yet has to be installed) - so after years using my X7 I am thrilled to return to my dear X5 !

I hope someone can help or maybe has done a similar thing. Any help is highly appreciated.

Cheers,
Karsten

Are you planning on doing rockbox development?  If not, there is probably not much point in compiling.  The code in git will give you an identical binary to what the download server provides (builds are actually done on individual users PCs).

Thanks Saratoga.

No development planned really.
I am pretty happy with rockbox the way it is.

The only thing I would change or add is maybe the support for large drives and SSDs.
If that makes sense...
Basically, what I want to know is what lines to add (and where) to improve the performance of my SSD.

Hmm - anybody ?

sorry, I know my DAP is rather old, so maybe not too many people are into it anymore... but still perhaps someone has done a similar thing or has a helpful hint to some place in the www.

Cheers

I don't think its realistic to expect someone to be able yo tell you how to improve ssd performance. You'll likely have to debug this yourself unless someone has by chance used a similar ssd and already solved the problem.

[Hogwash]

It does indeed seem that you are right with your rating of my problem.

It was after all my hope that somebody had that problem too and solved it.
From what I read it might only be (or: I hope that it is only) a line added in rockbox and/or the bootloader to remove the problem. The SSD itself is performing fine, perfectly aligned and everything.
Unfortunately I have NO experience with debugging and coding.

I still have my X7, so I'll just wait patiently and see if something turns up here.

Ok, so to not leave this thread open and unfinished I will post my part of the story here:

This thread:
http://forums.rockbox.org/index.php?topic=23436.0
lead me to the solution.
It was a little weird since things that were commented out in the config in my understanding seemed not to be in the end, but I just deleted the lines concerning:
#define HAVE_ATA_POWER_OFF
and that did it. "HAVE_LBA48" for big disks is compiled into the up to date rockbox by default, so just deleting that one line did the trick.

Now the next thing is to install that 1300mAh battery and I am a more than happy camper !

[wodz]

Not that much happy probably as not cutting power to the drive (removed HAVE_ATA_POWER_OFF) will decrease battery runtime considerably.

[Hogwash]

Well - I'll keep you all informed as soon as I have some long time experience with the new drive.

But since there are no more movable parts now AND the guy that I got the advice to remove "HAVE ATA POWER OFF" from has left his thread without furthur comment a long time ago - I have hopes that all should be fine.

@ wodz: In case there are things left to improve - what would you recommend instead of removing "HAVE ATA POWER OFF" ?
I am a newbie, so I am willing to learn...

Here are my battery benchmark results:

16h56m18s with my original (still the first) battery !
I played some 29 FLAC files in shuffle repeat mode, volume ca. 60%, screen only activated a couple of times to check status.

Well, I am definetlly not worried any more about removing the "HAVE ATA POWER OFF". 
I am quite impessed to say the least.
And: I have got my X5 back in even more glory then ever.

I attached my stats for the curious (I don't know LibreOfficeCalc well enough to provide nice looking graphs - sorry).
