It still hangs when I try to delete some directories on an 8gb card or create a bookmark for some files but it seems that all the other problems have gone. A card has been formatted before trying this new build.

When I try to boot anything r21578 or later, my Clip won't get past the bootloader.
Edit: It's not that simple. I'm still figuring it out

Edit2: Looks like it happens at random between r21577 and r21580.

I put in a fix for the bug in r21577 causing random lockups.  I think the input to the ADC was getting changed from CVDD while waiting for the voltage to be read and we were getting stuck in that loop.  The input to the ADC now gets set inside the while loop so if it does get changed while waiting it will be reset to CVDD the next time around the loop.

I have very poor sight and therefore pay more attention to what I am hearng. I have noticed when playing some audiobooks which are very quiet anyways that there seems to be another background sound behind the mp3 track. My first suspicion is that there is noise coming from the FM radio but it is soo quiet that i can not tell, but something is there and it is annoying.

I will produce a slient track and play it to see if i can pick up on the interferance in the background to help point to where it is comming from.

I haven't noticed that yet, but there are similar issues on the v1's. I guess you can't make cheap players while having a decent build quality which isolates background noises.

It looks like r21577 is also causing problems with the microsd (at least on e200v2).  It works fine with r21576.  It was not corrected with r21584

Symptoms are:

1) power up with microsd inserted - <microSD1> shows under files, but no files are listed under <microSD1>. 
System -> Debug -> View disk info shows "Not Found!" for [micro SD1]. 
Removing and inserting microsd does not help or or cause a hang.

2) insert microsd after power up causes a hang (backlight thread stills functions).

Can you try disabling interrupts in cpu_set_frequency()?

Upon inserting a MicroSD an interrupt is generated, changing the cpu frequency while that might cause problems.

I can confirm that behaviour on an e250v2. Also, if you go into System ->Rockbox Info the MSD free space/capacity are shown correctly, so the microsd is accessed and it locks up when trying to view the contents...

The fix is wrong, the adc input could still be changed in a tick interrupt happens after it was set and before it was read.

I suppose the battery readout is called from a tick task and change the ADC source but I didn't verify.

The correct fix like kugel suggested is to disable interrupts while waiting for the voltage change

I can't reproduce the problems on my Fuze. But I also never had problems with my MicroSD.

My Clip's working fine now!

[porio]

My Clip's working fine now!

Please, could you be more specific? What build are you using?
I've tried builds 21578, 21593 and 21613 and still can't get past the bootloader. Old build 21506 works (as well as many other older than that), but with the known random freezing issues.
I formatted the device and that didn't make any difference.
The bootloader build I have is 21444, can that make a difference? I tried compiling the bootloader from source... well actually I did it, apparently the compling process was successful, my Clip did the firmware upgrade but then it didn't work. I got a little scared and had to go back to build 21444 of the bootloader. What could I have done wrong? Where (or how) can I get a 'good' recent bootloader build?
BTW, I have a 4Gb Clip (v1, of course)

Thanks!

[kugel.]

Yes, please update the bootloader before reporting problems with booting.

[porio]

Yes, please update the bootloader before reporting problems with booting.

Thanks! Should I compile it from source or there is another way to get it?
(as I told before, my first attempt at compiling was unsuccessful, though I can try again...)

EDIT: I just compiled the bootloader from source version 21610. My Clip freezes at boot. Also, it can't boot to OF unless I plug it to the computer. May I have done something wrong?

[Hillshum]

I'm running r21579 for my bootloader with r21613 for the main build. Both work fine, with just the issue of playback stopping.

BTW, the playback crashes happen more on higher bitrates.
