Fuze V1 - Undefined instruction at 0x00000474

[Eibwen]

I tried installing with the 3.5 installer on a Fuze V1 2GB
I believe it would show the RockBox logo screen, then almost immediately show:

Undefined instruction at 0x00000474

It definitely did not show any UI.

I tried installing with both Firmware 01.02.26 and 01.02.31

Holding the arrow button to boot normal firmware worked, and flashing with original firmware restored it to working order

I did all of it on Windows 7 64bit.

Could you try downloading the latest build (from the download link on the left side of the screen) and unzipping it to your player?

[Eibwen]

I remembered slightly incorrectly, the error is "Undefined instruction at 00000474" (no 0x)

And it flashes the boot screen for less than a second, it is apparently "Boot Ver 1.0RC" then goes to that error message

Extracting .rockbox from build r24992 did nothing at all.


Using the manual bootloader install process (the versions linked to by this page http://www.rockbox.org/wiki/SansaAMS#Installation_for_Stable_e200v2_F):
Original firmware 01.02.31 gave an error message (the install program did not give any errors and seemed to patch it)
01.02.26 it says patched succeeded

But putting that firmware on still resulted in the same error

[funman]

Try removing the .rockbox directory:

If the error is still there the problem is in the bootloader

If instead you see something like "no .rockbox directory" then the error is in the build, and you can try using a current build to see if it fixes the problem.

[Eibwen]

The error is still there when there is no .rockbox directory, so the boot loader is not working on mine

[funman]

Dunno what happens there, bootloader is using 0x81000000 as base address, not 0x0.

This address is inside irq stack (minus 0x81000000).

Can you build a bootloader from current svn and install it manually with mkamsboot ?

Also what happens if you keep pressing the power button (or any other one but left) while powering on ?
The logo should disappear faster and perhaps text could be printed, depending on when the bootloader fails.

[Eibwen]

If i hold down any button other than left it just restarts immediately after flashing the error message
Otherwise it pauses on the error message until i press a button, then restarts


What would be the quickest way to be able to build it? A knoppix live cd perhaps?  Or would it not take much to get it to build in windows?

For how to build have a look here: http://www.rockbox.org/wiki/DevelopmentGuide#Set_Up_Your_Environment

There are many options to do it.  The Wiki contains all you must have to know.

Okay i built it just now, using the VM

I now have bootloader r25003-100303

And it goes directly to a white error screen with:
Undefined instruction at 0000048C

[gevaerts]

A wild guess, maybe the filesystem is corrupted? Can you run chkdsk on the fuze?

[Eibwen]

That did help a little

With the firmware i built i get:
Data abort at 810014B0

(ran chkdsk again here, and it found some more of the same problems as below)

Flashed with the manually created bootloader, said couldn't find firmware or something, using the current build

So i deleted the .rockbox that was there
Then used the 3.5 installer and it works


Thank all of you so much!


The installer works with offical firmware 01.02.31, but the mkamsboot.exe seemed to refuse it, that seems very odd to me.

This is because mkamsboot.exe is older than Rockbox Utility, and doesn't know about the recently release firmware
