I'm using adc5033-131121 version on a 4GB machine. I tried 131119 initially and reflashed and reformatted to see if it was a bad install but same exact results.

OK. Perhaps the cause is the sd/mmc driver problem that's also causing the different crash I see, manifesting differently on the 4Gb unit. I have no 4Gb unit to try.

[EDIT: Deletion of comment about Data Aborts, crossing with saratoga's answer.]

[saratoga]

The ARM docs explain in some detail, but basically it means you tried to read/write to an invalid memory address. 

[pamaury]

To be clear, there is no issue with the sd/mmc driver, the bug was cause by some other code providing wrong parameters and it has been fixed.
If you have a reliable way of triggered this new data abort with the latest revision, please post detailled explaination. As it is currently, it is too vague to be useful.

Also please avoid spamming the forum thread with known problems. I *know* there is a problem with the screen, no need to report it any further except to say that's now working. Also avoiding posting any report about data abort except if you can reproduce it and if you do, please post the *full* output of the panic, not just one random address displayed by the screen. Also mention the revision of your build at the same time, otherwise this data is useless.

Issue 1 - Return to Files on pressing Select on Now Playing (a.k.a. WPS) can cause crash.

Amaury, on Version adc5033-131121 (since this commit) I've been unable to reproduce this problem, so it may be fixed. I'll continue to test and let you know. Thanks!

[chrisjj]

display issues though, on all screens the background is displaying vertical lines in dim colored dots.  The WPS now playing screen is not formatted, all the info is there but the theme (CabbieV2) is not applied.  Alternate fonts and some themes seem to work well on the menu screen but even applying failsafe or default icons

MRJ, In case it helps: I found a 4Gb ZEN, loaded 131119 (and the unversioned but contemporaneous firmware_zen.nk), and tried those features and various others. I got no crashes. Apart from the known LCD standby exit corruption, the only run-time issue I found upon unplugging the USB after uploading RB and audio, is RB said: "Error accessing playlist control file." I updated to 131121 and found no issues.

I wonder if your problems arise from faulty formatting. Here there is still an issue with Format. On the above test, as before, Disk Management FAT Format reported failure, so then I did an Explorer FAT32 Quick Format, which reported success http://img62.imageshack.us/img62/2905/rtti.png . Perhaps it is worth you trying the later firmware_zen.nk (V1Beta2_fb8faa10) since Amaury reported that fixes http://git.rockbox.org/?p=rockbox.git;a=commit;h=bb8dd053434cbe9c98fe5b9a1095d00ebafb7b61 a problem related to formatting, albeit not one that TMK is known your cause crashes.

I updated the bootloader to HEAD, this way it now contains the fix for improper storage size detection. It is at the same address as before, cf wiki.

ChrisJJ,
I took your advice and loaded latest firmware and reformatted, both FAT and FAT32, and tested with 131120 and 131121 builds on Windows 7.  All versions had the same issues with background vertical dots and no formatting on the WPS screen.  I also tried the new firmware and a fresh reformat with the 131121 build on an XP machine with the same result. I am willing to try any ideas you might have. Thanks for your help, I'm going to try going back to stock and I will try future updates.

Thanks - got it. (FTR, from https://www.dropbox.com/s/cgqvrwr4qb3tb8u/firmware-zen.nk, dated 2013-11-23, showing on device as V1Beta2_fb8faa1.)

That solves the size problem http://forums.rockbox.org/index.php/topic,13462.msg221249.html#msg221249 on the 8Gb device. I.e. the formatted device is shown by Disk Management as 7.44 Gb and Explorer as "Capacity: 7,975,600,128 bytes 7.42 GB". Thanks!

But I see the format command failure remains. I.e. Disk Management says "The format did not complete successfully". The previous workaround (Explorer Quick Format) remains successful.

Also note that the instruction to be sure to format as FAT http://www.rockbox.org/wiki/CreativeZENPort is not performable on the 8GB model where Format offers only FAT32.

[chrisjj]

I also tried the new firmware and a fresh reformat with the 131121 build on an XP machine with the same result.

That's the very same recipe which works here. So I am baffled as to the different results. The only possibility I can see is some undefined behaviour, perhaps related to the failure of start-up to completely initialise the device, indicated to me by the fact that here some start-ups succeed and others fail, for no apparent reason. I'm trying to gather info on this for a report, and hopefully then it will be fixed, whereupon I suggest you try again. Sorry not to be of more help.

Issue 3 - Options (menu) and My Shortcut buttons have no effect

I'm guessing this is a bug, since http://www.rockbox.org/wiki/CreativeZENPort "Keys 90%  Buttons are working but the driver could be smarter and save power." and http://git.rockbox.org/?p=rockbox.git;a=blob;f=apps/keymaps/keymap-zen.c;hb=HEAD says

Two extra groups of button may exist:
  30  * (ctl) menu, shortcut
...
  34  * target  core ctl dir vol
...  37  *   ZEN    1    1   0  0

chrisjj,

A friendly reminder to consolidate your posts if possible, please.

Your enthusiasm is appreciated, but please try to avoid spamming the forum needlessly as it can be somewhat irritating.

[pamaury]

The button map is very very basic, it doesn't use most of the buttons and anyone willing to help on this matter is welcome.

Thanks. I made the last three messages as separate messages because they are on different subjects. If you'd like such messages to be combined into one, please do say.

please try to avoid spamming the forum needlessly

Please do point out any messages of mine that you consider to be spam and/or needless. Then I'll avoid posting such messages in future. Thanks Saint.

EDIT: I found two messages from me just saying Thanks and hence in in breach of forum rule 7). Apologies. I've deleted the content and if anyone can tell me how on this forum to delete a post, I'll do that too.

Thanks. I find eight buttons work, and only these two don't.

and anyone willing to help on this matter is welcome.

I've updated http://www.rockbox.org/wiki/CreativeZENPort to accord. I'm happy to help any coder with design and documentation on this.
