Rockbox and Compact Flash

[1ny0urfac3]

Those guides mean almost nothing to me.  I only have a little bit of experience with linux running ubuntu for about a year but I no longer run it.  Do I need to run ubuntu inside of vmware to compile that?  *EDIT* ok I kind of know what I need to do but I'm still almost completely lost?  any chance you can upload the build to a site?  sorry.

I'm afraid it is not so easy as this mostly a trial and error process, and your iPod is not the same as mine, we can be producing builds, uploading to a site, testing ...

Believe me; I'm not a Linux geek either, and once you install the right dependencies (as from the cross-compiling tutorial) and having the PATH correctly set (Same tutorial) you just need to follow these steps

svn checkout svn://svn.rockbox.org/rockbox/trunk -r {2008-02-09} rockbox
cd rockbox
mkdir build
cd build
../tools/configure (select your port and build type Normal)
make
make zip


I'm now building some releases in subsequent dates. I've seen ata.c had a change on Feb 17h hence looking the most suspectful date. Will inform on the results.

Once done you'll have a rockbox.zip file in the build directory. This is the compiled build

Thanks for your help, I just got done and it ended in failure.  my compilation has something wrong.  I think I'm just gonna wait it out until a new build comes along with support.

[Llorean]

That's the thing: The current build is supposed to already HAVE support, and people who it's not working for need to do the testing to figure out what's wrong. If not enough people who actually have problems test, it won't get solved. "Wait and it'll go away" doesn't really work if everyone waits.

[1ny0urfac3]

what should I do?  I really have little to nothing to offer as far as coding or anything like that.  if you want me to run some kind of test or something I'm more than willing but I'm afraid I'm not much help here

[Llorean]

Just as it said just a little earlier in the thread, track down which version made things change.

[viperX]

OK, did some more research and can hereby confirm the breaking point was on Feb 11th as said earlier.
Release 16256 works (given by SVN when requested for Feb 10th)
Release 16276 doesn't work (dito for Feb 11th)

EDIT:
Learning as I speak, found where to check versions on the web page and I strongly suspect the problem was introduced on revision 16259 as it touches a lot from the core on the ipod.
http://svn.rockbox.org/viewvc.cgi?view=rev&revision=16259

"Disables much of the remaining unneeded hardware on PP50xx targets (Ipods, Sansa, H10s, etc) resulting in a large savings in power and consequent increase in battery life.  Results vary from target to target and from codec to codec, but we now approach the OF runtime on several PP devices."

We seem closer, but this is where I should stop since I don't have programming skills, unless someone guides me on what to do.

congrats, that looks like a good candidate....

You can request specific SVN revisions, rather than just dates, so you can get closer than a 20-revision range and verify it's that one.

I think that is what he did:

Nonotice that he said he got those revisions when he requested dates. They're 20 revisions apart.

* petur puts on his glasses

[Llorean]

That being said, it does seem likely his guess was right. I was just suggesting that he could in fact verify with one or two more builds tested.

[viperX]

Thx for the expectation  , I've seen how to request by rev number and I am almost ready to test, but unfortunately I've been on travel I won't be able to test before tomorrow morning CET (in a matter of 10 hours)... please stand-by.

Regards

*EDIT*:

TESTED and CONFIRMED; the problem is in revision 16259. 16258 works fine booting in a matter of less than 3 seconds after the apple is shown.

Unfortunately this hits my limits now and I'm even unable to build any release since I'm on travel and don't have my Linux environment with me, so I give way to the real developers to take over the issue, hope someone can find a solution soon since my old 4G really needs the extra kick on battery lifetime.

Could you email me a copy of revision 16258?
