Re: Questions relating to undervoltage in B+

I tried reducing USB devices, but in my case that did not have any significant effect. However, I wrote and read large amounts of data to test the performance of a usb stick and the sd card (I know that this is causing wear and tear on them). When performing the I/O-events on the stick no warnings, ...

Re: Questions relating to undervoltage in B+

I'm not sure that I can rely on myself enough to go through with the operation of splicing the cable etc. But perhaps I will try another PSU and the cable mentioned here first, then see what I can do with the existing one. Does anyone have any good links to any good prayers or magic to help?

Re: Raspberry Pi B+ Booting Problem

how did you use it? did you save the .img file from the net on to the mac, and then copy it to the card via USB? Or did you use an imaging software to get the NOOBS on the card?

Re: Questions relating to undervoltage in B+

[ ... Otherwise suggestions to get a new PSU or cable sound good, except that it seems that there is no way to know in advance which PSU might be good or not. People seem to give advice more based on presumptions and racism ("don't buy Chinese cheap) than on some objective verifiable citeria. I sus...

Re: Questions relating to undervoltage in B+

W.r.t. to the SDHC card that does not appear to exhibit "brownout detection" - is that the one with Openelec on it? If so it's possible that it does not have the most up to date firmware on it (there were some changes to the firmware during the first week or two post "B+ release"). What versions (d...

Re: Questions relating to undervoltage in B+

Yet, the worst thing that can occur is card corruption, is this correct? Or can something more serious such as permanent hardware damage occur? If the PSU cable is the problem, then can one possibly get a better one than from a vendor which claims to have specifically designed their product for the ...

Questions relating to undervoltage in B+

I know next to nohing about Linux operating systms or electronics, so bare with me, even if this is dumb. I have a B+ and I have set up two micro sd cards, one with Openelec and another with Raspbian. (I didn't realize when I did this that with a NOOBS one could easily set these two up on the same c...
