Creative Zen Vision:M

[mcuelenaere]

hi,

i seam to remember that on some targets the bootloader doesnt have the interrupts enabled, and thats why the replace the sleep with a loop.
Perhaps this also the problem here ?

good luck..

I looked in it a bit deeper and I don't think the problem lays with the interrupts (standard all of those are disabled, except the ones for the timers).
BTW, what kind of interrupts should be enabled you're talking about?

I think it has something to do with the task switching, although I don't really know what. Maybe it is trying to access some address that it isn't allowed to touch or some address that was set up in the previous bootloader and is still in use...

Also it seems like there's some problem with the timer handling; as it gives me a panicf() for an unhandled TIMER3 interrupt while that interrupt is nowhere in the code enabled (TIMER0 is used for this)...

Hi,

I've been watching this thread for some time now. And I want to help too. But I cannot get the bootloader to compile. I can compile bootloaders for other targets, but not for the zvm. All I get is this message:

Code: [Select]

In file included from powermgmt.c:45:
export/font.h:30:21: error: sysfont.h: No such file or directory
make[1]: *** [/home/Dennis/rockbox/zvm/firmware/powermgmt.o] Error 1
make: *** [bin] Error 2
I am using Cygwin, the latest SVN patched with the last zvm.diff. I tried compiling with a compiled sysfont.h from another target but that doesn't work to. I also tried compiling it in native linux. Didn't work either

First, try 'tools/rockboxdev.sh': this will install the latest (needed) compilers and toolchain.

You did run 'tools/configure' correctly and selected BOOTLOADER ?

I had that problem too.
try this in the folder where you want sysfont.h: "../tools/convbdf -h -o sysfont.h ../fonts/rockbox_default.bdf"

Ok, I finally found out what the problem was with TIMER1 who didn't want to accept any values: it just didn't get any clock

So now I've got the tick task working (and interrupts), but still the sleep() problem exists so this will need some more looking into...

Diff is attached (I know, it is very dirty and messy; but I don't have any real debugging tools so I just got to printf() everything I can)

edit:
re-added zvm.diff : added some USB stubs

he mcuelenaere, when I update to your new diff, it gives me a lot of warnings (which isn't so bad) but it also give me an error on how 'CLK_MOD2_TMR0' isn't declared.. which is less desirable because now it won't do stuff..

Did the patch apply correctly at firmware/export/dm320.h ?
Because there's the (new) definition.

Ok, so now the HDD works (although I'm not sure if ATA_CONTROL is correct; but that doesn't matter that much) *but* it requires some modifications to thread.c which are pretty bad.

Apparently load_context() just doesn't work on the ZVM; for some unknown reason it crashes/restarts when executing this code..

Also code is a bit more cleaned in this diff.

Will this port also work on the Creative Zen V Plus? (Or at least, is it likely that there is a high chance?)

Keep up the good work with Rockbox.

Keep up the good work with Rockbox.

Not directly, but with some help of Creative Zen V (Plus) owners/hackers they will (hopefully) be able to use it without much effort; but I think the Zen V differs more to the ZVM than for example the Zen Vision or the Zen Vision W..

As for Rockbox, I will be focusing on getting USB up and running so I can set up a serial driver for debugging purposes (I want to thank Frank Gevaerts for doing a lot in this area ; actually I was planning myself to do the logf() thing he did yesterday, but he was faster)

Update:

interrupts should now fully work, there remains only one problem with the TIMER1 interrupt: for some unknown reason an CCD_VD0 interrupt is given when TIMER1 interrupt is enabled..

Also it seems as the PIC gives a non-stop interrupt to GIO0 whenever a button is touched, so I presume it is waiting until the ARM starts contacting him and asking him what button has been touched (to be worked on..)

UPDATE:

Buttons work!
The button driver fully functions, only current limitation is that pressing 2 buttons at the same time is detected (probably because the PIC doesn't give us that information); this is only possible with the hold switch.

Next up is the RTC, but for this I need (more) (high quality) pictures of the ZVM's internals; I already opened up mine twice, but as I find it a bit too 'scary' detaching the LCD of the main board, I'm asking somebody else to do this (to a non-working player perhaps?)

So could someone upload some pictures (if possible, made with a digital SLR )?

Oh yeah, patch is attached..

@Falafel: I think this won't work with the Zen Vision, because the PIC used in the ZVM either isn't used in the Zen Vision or isn't at the same I²C address; if so: please say

mcuelenaere: I see you are doing some great work! Maybe it is time to open a flyspray task and upload your patches there ? You'll get much more visibility from developers there. Also, take a look at docs/CONTRIBUTING for the code formatting guidelines, it will make getting your patch committed much easier

Ok, done.

Attached is a fresh one, try it.

Nice that you also come join in the fun bobbaluba
