[Sansa Clip v2] - Blank Display [RESOLVED]
« on: March 03, 2016, 05:16:12 PM »
Hi

Installing the development version (5138995) on my sansa clip v2 displays a blank screen straight after applying the firmware. Rockbox seems to be running in the background as the clip lights up when buttons are pressed and occasionally the screen re-appears. I'll edit this post again if I can confirm which buttons worked. Btw, the stable release (version 3.13) works without any problems.

:)

Same blank screen I'm afraid :'(.

When I switch on the clip, the rockbox logo appears briefly and then the screen goes blank. Shortly after this, the arrow keys and circle light up blue and then turn off after a couple of seconds.

:)

EDIT: Btw, booting into Sandisk's firmware (left arrow + power) loads fine.

Ok so its probably not my recent frequency scaling changes.  I'm not sure then, have you tried any builds since 3.13 but before this month?  A lot has changed over the last few years.

No, I haven't tried any of the previous builds. I have been using the Rockbox utility to pull down the stable and development versions. Is it just a case of unzipping these builds and then copy/paste onto the root of the clip? (deleting the previous version first).

I'll test a few and report back which is the latest working version.

:)

EDIT: I have tested the latest builds of each Rev (2016-02-16, 12, 7 and 6) and all show a blank screen.

Unfortunately we don't provide binaries for old development builds so you would have to compile them yourself. I was hoping you had tried some builds in the past and could give some clues.

Sorry, I only joined the other day :). Not to worry, I'll put the stable version back on. Thanks for all your help. Appreciated.

Me too. This happens with 5138995 build only.

Try this build:

www.mit.edu/mgg6/www/rockbox-clipv2_noscaling.7z

In this build you just disable scaling or reverting whole patch? Possibly we still have some timing issue on cliv2 with new frequency.

No, I just disabled scaling.  Here is the last version before any changes (1015088d90275336e7b999624d2524800b8aa3e8):

Hi saratoga

Just letting you know that this version works with my Sansa Clip v2. I'm not sure if I did the right thing buy moving the existing ".rockbox" folder to my harddisk and then extracting the file above onto my SCv2. Displays the new version when booting Rockbox now so I guess all went well.

In lcd-clipv2.c we have #define LCD_DELAY 10 and  while(i<LCD_DELAY) i++;
Probably we should change it or replace with udelay.
