Re: The Raspberry Pi 3 Model B Q&A thread

Fri Mar 04, 2016 2:26 am

I have 2 questions about the pi 3 currently.

1. does the boot/config.txt support a [pi3] for pi 3 specific configs like it does for the original pi and pi 2?

2. is there a way to control the pi 3 ACT LED from a GPIO like we could with the pi 2?

Same question, maybe someone can enlighten us.

I think there is something wrong with the on-board leds.
In "/sys/class/leds", there is only led0, there should be led1 as well which was the red power led.
How do you turn off the red led?

The LEDs (and others) seem now to hang off a GPIO expander - the WiFi/BT combo chip gobbled up so many there weren't enough left. No idea about the details yet.

From what I have seen, I am led to believe that the LED's are now controlled through a Mailbox, the additional class for the virtual GPIO seems to be using one of the Mailboxes, but I cannot confirm yet.

hardinfo benchmarks for RPi3 anyone?

Fri Mar 04, 2016 9:35 am

Hi,
can anyone provide the hardinfo benchmarks for RPi 3 (Blowfish - CryptoHash - Fibonacci - N-Queens - FFT - Raytracing)?

Thanks!

$35 is the price. This is not a sale, this is simply selling. Why do you think it's a sale?
Everywhere but in Sweden that is. The MSRP is 499 SEK or the equivalent of $58.50. Taking the British MSRP and adjusting it for Swedish VAT we'd end up at 390 SEK so that's a good $12 or so difference :(

(The RPi2 is still available at some retailers for the same 399 SEK as when it was introduced)

Anyone else having reboot issues after getting the latest firmware update via sudo rpi-update?
I ave tried latest version of firmware with a clean install on 2 Pi3s and both are failing to reboot after the update appearing to indicate SD card removed.

Yes, don't do rpi-update unless you have a very specific reason to do so (it's been deprecated for some time as a way of updating firmware). Just use

sudo apt-get update
sudo apt-get upgrade

Yes, same here, when I did a "rpi-update" this morning on my Ubuntu SD-card for the Pi3.
The Pi3 loader from the /boot partition doesn't load Linux from SD-card then but reports your mentioned errors.

Indeed, with Raspbian I always do so, but I tried to update my Ubuntu (Mate) SD-card for the Pi where we don't get the new Raspbian kernels and firmware with "apt-get dist-upgrade" but with a "rpi-update" only. This method worked well until today.

Can you try updating again? I've pushed a possible fix.

I seem to have it working in AP mode now. I had a working AP mode setup on wlan0 and when i updated my raspian i got a wlan1, then i removed my WIFI dongle and rebooted and it started working with the internal WIFI.
I do have some problems with some of my WIFI devices that had to reconnect and stuff. But it seems to work.

And make sure your using hostapd from Raspbian repo (not other hostapd binaries that are floating around):

Note the green ACT led is there in /sys/class/leds/led0 and setting the trigger works.

since i'm a little bit scared of power consumption test you can see out there (i.e. https://hackadaycom.files.wordpress.com ... ercon1.png ) i'd like to know if someone tested power consumption between a pi3 and a pi2 with wifi and bt dongles..

Edit to add:
this seems to see things in a different way

What are you scared of ?

As a comparison, are you scared of boiling a kettle ? That takes over 10 times the ampage of the RasPi in your linked image ...

it's only a matter on consumption.. my principal PI is managing my domotic system, i don't need a lot of power, so i was "scared" to double the consumption to have power i'm not going to use..
that's all :)

(i know it's a matter of a couple of £/year)
(i've already ordered my brand new pi3)
but i'm still curious of a consumption test BOTH with bt and wifi :)

leave the exsiting one doing that job - does it need more power or can you even replace it with a model A ?

The device tree is set up for the RPi 3B to look at a "Virtual GPIO", looking at the driver that has been created for the Virtual GPIO, I am under the assumption that this is pointing to an address relevant to the VPU (based on commit comments) which seems likely considering the boot process for the RPi's has always been the VPU turning on first and booting up the ARM core.

Based on the commits, the ACT_LED is Pin 0 on the new Virtual GPIO. The firmware header holds a value of 0x00040010 for the Virtual GPIO.

Hmm... I wonder what is preventing the BT module from working with the mini uart?

It would not be acceptable to have the serial baud rate fluctuate with changes from the performance governor, so I doubt that is the case, as it would bust all serial communications with the Pi3.

Could it not simply be that the problems which could afflict the now exposed user UART would afflict BT comms, and present an even greater problem there ?

One solution is to order from e.g. Pimoroni and with the exchange rate that VISA had it's 440 SEK including shipping (£4). I used £1= 12.2471 SEK, because VISA adds 1.65% to the exchange rate. Last time I ordered it took a week to Sweden. If you order more things you save even more because the shipping is fixed.
