SanDisk Sansa c200v2, m200v4, clipv1, clipv2, clip+, and fuzev2
saratoga:
I received my e200v2. If anyone wants power measurements taken, please let me know. I can easily measure current in real time using a DMM for any rockbox patch by removing the battery and using a power supply.

I updated both build and bootloader. I cannot see the bootloader screen. OF works fine.
I used bootloader-clip.sansa for making the bootloader with mkamsboot. Is the file correct?

Can't resist a new toy and I'm a visual type-o- guy so just to show what's possible once we figure this darned mmu thing out I got some screen shots to show you. Its running on 192/32/32 with mmu and both caches enabled, and as you can see it's only boosting 10% of the time and averaging a bit more than 48MHz while playing an mp3 file. You can see a bit of corruption in the screen but funman's last patch corrects this. Playback with cached memory is still not working reliably for me though. One interesting thing I have found also is that for some reason if I use a plugin that has playback controls to start playback I get a much higher chance of music playing for more than 4-5 minutes. Another thing is that as long as I don't attempt to play music, Rockbox runs very well. I can play games all day long and when I hold the power button down to power off it has a normal shutdown. Once I play music on it though I end up having to hold the power button for 10 secs to force it to turn off. I was wondering if the fact that things run better when started from a plugin point to a buffer conflict with the plugin & audio buffers?

Yes it's the correct file (Clip bootloader).
You should try earlier revisions (bissecting) until you get display working, or perhaps tweak the delays in firmware/target/arm/as3525/sansa-clip/lcd-ssd1303.c
@FlynDice:
The plugin & audio buffers are separated (see app.lds), so I suspect a difference in timings.
Perhaps we should look again at the i2sout registers, there is some bits we don't use and the OF does.
@All:
I tagged a 1.0 release of mkamsboot (the tool to patch OF files) and you can get binaries at http://download.rockbox.org/bootloader/sandisk-sansa/mkamsboot-1.0/ (OSX binaries will come in a near future)
jago:
With recent revisions the radio of my e200 isn't working anymore.
If I switch to radio mode it shows only the status bar on top and freezes then.
After some investigation it seems that rev 21088 is messing something up.
