Re: Who's got their hands on a B+ so far?

Wed Jul 16, 2014 1:21 pm

My first try with B+ existing microSD card booted up with "dead" USB (i.e. old firmware),
also the green ACT LED didn't light up during boot either ?!

So I downloaded a new NOOBS (lite) to the card and after that all is well - LEDs lighting up as expected,
and raspbian downloaded and installed fine.

Just transplanted the card back to the 'B' it was cloned from.

Halts correctly there. Very strange.

@mikeerr, I tried a fresh raspbian image from yesterday and that had working ports but still had the halting issue. Maybe NOOBS is different in some way. I'll give it a try when I get half an hour.

EDIT: I was about ready to take this aside to the troubleshooting sub forum. However, on returning the uSD card to its place in the model B+ both halt and shutdown now working as expected.

I did nothing to the card beyond moving it there and back again.

@Dom, still no 10 flashes of ACT at shutdown, though ACT behaves as it did before at all other times.

Do you happen to know / where can I find out which GPIO it now uses?

You'll see in /proc/cmdline

Code: Select all

bcm2708.disk_led_gpio=47
So, it's GPIO47.

The one I ordered via CPC Farnell "after lunch" on Monday arrived in the post today. Fitted some nylon pillars into the mounting holes (in lieu of a case). Used GParted (on my Ubuntu netbook) to reformat etc. a 16Gb Samsung uSDHC, downloaded NOOBS 1.3.9 lite and unzipped it to the card. Plugged everything else in, switched the (shared) monitor to DVI mode, powered up the B+ and "et voila", the NOOBS O.S. selection screen appeared eventually. Selected Raspbian and clicked install. All appeared to be going fine until I got a "... downloading or extracting tarball ..." error pop-up. On clicking "close" this led to filesystem mount issues and a kernel panic. Powered down, waited a few secs. then powered back-up. This time Raspbian was installed w/o any further problems so I guess there was a "network glitch". (I have monitor 'photos of the kernel panic stuff if needed).

Still running Raspbian Jessie or Stretch on some older Pi's (an A, B1, B2, B+, P2B, 3xP0, P0W, 2xP3A+, P3B+, P3B, B+, A+ and a B2) but Buster on the P4B's. See: https://www.cpmspectrepi.uk/raspberry_pi/raspiidx.htm

In the past, I've only ever come across kernel panics when timing/power issues have caused SD access problems, the kernel panics and switches to read only. I say timing/power because from my experience, it has only ever been caused by the SD card not being powered/clocked properly. SInce the reboot and take 2 fixed it, guess there's little point worrying now.

Received four boards yesterday from Farnell
On the old model B we performed
sudo apt-get update
sudo apt-get upgrade

Then moved the micro sd over to the B Plus. Our project which uses GPS, wifi and Iridium satellite comms and is working fine.
Our big issue with the model B is it only has two holes for screwing it down. Four holes make mounting much more solid. Very nice improvements overall, and may I say, sensible improvements. We are now switching to B Plus and will use our old Bs for training.

I have my B+, been looking for a case to fit. Need it to be as minimalist as possible. Does anyone know of one available?

Thanks.

One I ordered on Monday from CPC arrived today. Works as expected, tested the USB hotplug with a keyboard that reboots my old boards. No problem on the B+. Much less of a wiring octopus than an old board.

Do you have latest bootcode.bin? It should be useing the ACT led for the flashes.
I have the latest from apt-get update/upgrade. I don't use rpi-update.

Just re-checked - and it's not pulled new firmware.

if that helps...

The ACT LED works fine in the kernel for the SD card access, but it reverts to the old LED at halt time.

Anyone else saw this strange feature. Three of my B+ boards have the following LED action ACT=flashing green and the PWR=red, but on the fourth board, using exactly the same set-up the PWR led is green rather than red. It all works just fine so not a problem just strange.

Photo is not great (Phone camera then squashed to get it on the forum) but you can see top right the PWR Led is red in one board and green in the other. Ignore the ACT green LED as this flashes so its a bit random if its on or off when I took the photo.

I hope the document all the board test points like the RUN test points. May be handy.

Can you post a photo?

Edit:

Heh. The LEDs are swapped. Does the ACT LED work at all?

New B+ is much neater and prettier. There's an obvious increase in engineering thought, time & money gone in to revising it. It's lovely!.

All fine with the Raspbian partition of a previous NOOBS microSD, but the NOOBS software itself appears not to have drivers for the upgraded USB hub/ethernet IC, as I cannot select OS's from the NOOBS menu.

Is there a way to update just the NOOBS boot partition?

I got one in yesterday from the good fellows at Pimoroni - it's running quite happily with a 64gb Sandisk microsd card.

You might be able to send it back for a replacement?

Yeah, the firmware in the repository (installable via apt-get) gets updated at a much slower rate than the firmware installable using rpi-update. I think http://www.raspberrypi.org/forums/viewt ... 66&t=80023 is aiming to be the best of both worlds ;)
The ACT LED works fine in the kernel for the SD card access, but it reverts to the old LED at halt time.
Yeah, while Linux (kernel.img) is running, Linux has control of the GPIOs. Before or after Linux is running, bootcode.bin has controls of the GPIOs. And the problem is that in the 2014-06-20 version of Raspbian (and the current "apt-get firmware version"), kernel.img has been updated with the new ACT LED GPIO, but bootcode.bin hasn't.

Sounds like someone put the wrong reel on the pick and place machine, I suspect there are a few thousand like it.

Which version of NOOBS was that? What do you mean by "cannot select OS's" - the keyboard (or mouse) is totally unresponsive, or something else?
Is there a way to update just the NOOBS boot partition?
It's not really recommended, but you could try extracting the files from NOOBS Lite over the top of your current RECOVERY (i.e. NOOBS) partition? Note that this obviously won't update any of the OS installation images, and in versions of NOOBS prior to 1.3.8 not all the OSes are compatible with the Model B+. And if you *do* try this, you'll also need to take the 'runinstaller' option out of recovery.cmdline to stop NOOBS deleting your existing partitions.

Recommended solution is to just backup any files you need, reformat the card, and start afresh with NOOBS v1.3.9 ;)

I thought I remember reading that the machines scan the barcode on the reels as they get inserted, to prevent that kind of error?

UPS dropped off the three Pi B+'s I ordered yesterday morning around 7pm tonight!!!

Looks great!

Love the extra USB's & GPIO's, and better power supply.

Finally got high current mode to work on my Pi. I had to use the "old" style gpio safe mode flag even though I'm running the latest firmware.

For some reason my config.txt is getting wiped on a reboot, and if I try to modify it from the running Pi I get an I/O error on save. I'm hoping it's just a dodgy microSD and [email protected] replace it and try again.

My Portapow power meter should arrive today so I'll do a comparison on my blog of the power requirements etc.

Can't wait.
