I would like to know if anyone knows, what are the difference between Rpi B and B +, except some hardware modification.
I was never able to manipulate B, I am using some screens I saw and what I saw on the B +.
It seems to me that the processor remains the same (ARMv6 compatible processor rev 7 (v61).
2 additional USB port.
Transition from SD to μSD.
some change, but which one exactly?
And most importantly, the question I ask myself, why it affects the functioning of a OS working properly in B and not in B +?

better power management
the LAN9514 is now clocked from the SOC for less cost so the old firmware could not drive the new options

Re: Difference between B and B+
Don't forget the composite video moved from an RCA connector to the 3.5mm jack.

Re: Difference between B and B+
Plus ...
- 4 mounting holes
40 pin GPIO header
Power socket moved to HDMI side
Ethernet port now has status LEDs

Re: Difference between B and B+
Thanks everyone to answer so quickly
I have forgot about composite in jack
The main thing i don't understand, is why, even if the architecture of the processor seems to remain the same, the raspberry B+ is unable to recognize an OS which is known to work on B.
Does status LEDs of ethernet port are the same than the former led on the board?cause i can see two led on the ethernet but from what i've seen, there were 3 leds on the board for the ethernet port.

Re: Difference between B and B+
That's because the 25MHz crystal for the USB and ethernet has been removed and replaced with a GPIO based signal generator. That fundamental hardware change needs a firmware/bootcode change to implement it.arwald wrote:The main thing i don't understand, is why, even if the architecture of the processor seems to remain the same, the raspberry B+ is unable to recognize an OS which is known to work on B.

Re: Difference between B and B+
...and the LAN_RUN signal (which 'turns on' the LAN9514) has moved to a different GPIO pin, and the Activity LED has been moved to a different GPIO pin, and (other changes we're unaware of until the schematics get released) ...DougieLawson wrote:That's because the 25MHz crystal for the USB and ethernet has been removed and replaced with a GPIO based signal generator.

The old firmware / operating systems technically will boot (since the SD card is still connected to the same pins on the SoC), but for two different reasons described above the LAN9514 will be non-functional, which means no access over Ethernet, and no access using a USB mouse or keyboard. Which makes them not very useful

Summary

My ears do not hear problem in RPiB sound so RPiB+ must be real HiFi then.

Re: Difference between B and B+
Also,
- current monitors on the USB ports mean the B+ now supports hot plugging.
- Current limiter on the 5V for HDMI means HDMI cable powered VGA converters will now all work
- 14 more GPIO pins,
- Four mounting holes
- EEPROM readout support for the new HAT expansion boards
- Higher drive capacity for analog audio out, form a clean separate regulator, means a better audio DAC.
- No more backpowering problems, due to the USB current limiters which also inhibit back flow, together with the "ideal power diode".
- And probably many other things i've forgotten

I'm finding it odd that there doesn't seem to be a Foundation page describing the differences! I've not got much on, perhaps I'll knock one up for the documentation!

I suppose there have already been people asking for a B-

Re: Difference between B and B+
I suppose I have a B- as its one of the ones with poly fuses and 256Meg.
Note: This is not a complaint. I am happy with what I have. I will be getting a B+ as soon as I have the cash.
