Re: Power supply voltage exceeded

@{myself} Unfortunately, no one seems to know the exact specification of the SMPS [Someone suggested it might be a NCP6343 -- Which has an input voltage max. of 5.5V -- Is it really a NCP6343?] I used a very strong lense to see what is engraved in the silicon surface. It says: "6343 dAF04" At least ...

Re: Raspberyy pi 2 components list

@kotlitonis
I searched google and found schematics
Those are of the RPi1 B Rev. 2.1, the Pi2 schematics weren't released yet nor is there any information on the components :(

Re: Power supply voltage exceeded

Sigh great... My session timed out while writing this post.... so again: @Trevor There are worse ones "out there" such as this "A1399 clone"!!! Isn't it hard to manufacture a charger that behaves in such a horrible way? :lol: I wonder what happens if you connect a cellphone to it, drawing more than ...

Re: Power supply voltage exceeded

The iLuv PSU seems to be a engineering desaster :? AIUI the 5V +/- 0.25 specification really applies to attached USB devices and/or many 5V devices powered (by the Pi) from the GPIO's, rather than the Pi's "on-board" voltage regulators (which provide the Pi's 3.3V & 1.8V supplies). Yes, the voltage ...

Re: Power supply voltage exceeded

@RaTTuS you possibly had a bad USB lead before That's what they are all saying, I cut the lead open... It was a standard shielded usb lead made of stranded wires (which looked not too thin...) I rather think the power supply is was not that good... @Trevor Wow, thank you. That side is really interes...

Power supply voltage exceeded

Hi, I am having a little trouble with my RPi2's power supply. My USB charger (rated 5V2A) didn't deliver enough voltage... at least the RPi2 complained <rainbow square>. Therefore I took a look deep into my drawer and found a Linksys Power Supply (rated 5V2A), originally from a NSLU2 (which eventual...

Using gpio_keys to control xbmc/raspbmc

Hello, I have attached a few pushbuttons to the raspberry pi P1-header pins. Then I configured the bcm2708 platform file of the kernel similar to http://www.raspberrypi.org/forums/viewtopic.php?f=50&t=8842 and rebuilt the kernel with raspbmc's configuration. After replacing the kernel and it's modul...

Re: USB FIQ testing....

Hi, I want to code a little workaround for my soundcard's driver (which i mentioned before). Unfortunately I am not so into USB. Thus I would like you to tell me if the workaround I am considering is possible... Workaround idea: Due to "esoteric" many endpoints I thought of ignoring all unneeded end...

Re: USB FIQ testing....

@gwlevans I tried this in several kernel versions before. Although the message disappeared in some tests, distortions never did so. Thanks anyways. @P33M There are lots of connectors mic,phono,optical, indeed. I guess that making this device work will take a lot of time. Let me know if I can provide...

Re: USB FIQ testing....

I tried this yesterday, and it has made a Sound-Blaster X-Fi Surround 5.1 Pro usable Previously it had lots of drop outs and clicks. Now I hope this fix will quickly find its way into raspbmc. Hi, I thought that the "Sound-Blaster X-Fi Surround 5.1 Pro" chipset might be similar to my "Sound-Blaster...

Re: Another USB sound question

Hi,

I set the maximum packs to 256 and compiled my own kernel. Unfortunately this didn't do the trick. I set nrpacks to several values but everything remained to distorted.
(I was using a SoundBlaster X-Fi HD USB)

Sigh, I long to see those damn USB Driver Problems solved...
