4th Gen Grayscale Undefined instruction repeatedly

[krylon]

I have a 4th gen grayscale ipod 20gb.  I've been using rockbox for about a week now and I keep getting

 

Code: [Select]

Undefined instruction at XXXX 

where XXXX is 0005786C for this build.

I get this while playing music and just leaving it alone.  I think on yesterday's build I was getting 0005797c.  Before that 00057938.  

Obviously I have tried multiple firmware builds. I've also tried reinstalling the bootloader tool here:
http://download.rockbox.org/bootloader/ipod/ipodpatcher/win32/ipodpatcher.exe


Any ideas?  I have not modified this hardware in any way.

what is the last build that you have tried? I had the same problem but it went away when I installed the July 11th build... although I have had some other bugs now including not being able to enable the cuesheet support.

Update to a current build.  There was a fix committed yesterday for this issue.

(The fix was r13991.  When Rockbox boots, look at the version number.  If it is less than r13991, you should update.)

I went to that current build and it went right back to the same problem... as of now, I am going back to the July 11th build as that one doesn't crash  

This time it seems to happen either when I've had it on for over 30 mins or when I am multitasking on the system...

I generally use rockbox for about 2 hours a day so if you need me to test it daily for you to help resolve this issue, please let me know.

Now, did you download from the "Current Build" page or did you download a daily build dated today?

Also, what bootloader are you using?

[bzbire]

It was the daily build dated on July 26...
I had uploaded the most recent bootloader on July 11th

Things are back to working on the July 11th build by the way.

The July 26 daily build was r13989.  You need a build with r13991 or higher, which is why I told you on July 26 to update to a current build, not a daily build.

[bzbire]

ah gotcha... so stay away from the daily builds for the time being then?

[Febs]

I did not say to stay away from daily builds generally (though we generally recommend that you use the current build).  I said you need to use a Rockbox version greater than 13991.  You chose a daily build that was revision 13989, so it did not contain the revision that you needed.
