New Raspberry Pi model 3B+ 1.4 GHz, 330Mbit Ethernet, 802.11ac, PoE

[Gergmchairy]

Hi All,

Thanks again - Confirmed - latest stretch lite - and it works fine. Disappointed that i bought the Pi3B+ and NOOBS Card (i just needed another sd card really) from Pimoroni together and they supplied an old os that didnt work with the 3B+...

NOOBS Card (i just needed another sd card really) from Pimoroni

Do they still sell those old ultra slow SanDisk cards (black) or the fast A1 cards in the meantime?

[fanoush]

thanks - got rid of wheezy and jessie but still no dice... hmmm
anything else I can try to update ?

sorry, I am not at my Pi now but if you have working card from fresh image then you may check which repositories are set up there and see version of bootloader there.
Maybe the mirror at mirrordirector.raspbian.org is not updated yet? Or you are missing some repository source.

The final image took a while to finalise, so unfortunately none of the distributors would've had a card they could ship with it on launch.

[Gergmchairy]

Understood, might be worth warning people - lots are likely to get the Lightning Bolt issue and be checking their PSU when its nothing to do with it (well it might be, but ...)..

Greg... see my stuff above - going through this stuff right now... Lightening bolt.

for some reason you have old bootloader

Code: Select all

raspberrypi-bootloader               1.20170703-1

it is unlikely that version from 2017/07/03 is recent enough

Sorry, it looks like the correct package which contains /boot/bcm2710-rpi-3-b-plus.dtb that you are missing is raspberrypi-kernel not bootloader so the version of the kernel package is important. And the latest version of that one is 1.20180313-1

Both are important. Without latest firmware package no DVFS support and booting stuck with lightning bolt usually signaling under-voltage.

I just unzipped the lite image and both kernel and bootloader have version 1.20180313-1 there. Can't find those at http://archive.raspbian.org/raspbian/pool/ but maybe I am not looking at right places.

[pi-man-uk1]

just trying to work out how to update to get the card bootable in the new pi.

Not there yet. Just tried copying the contents of /boot from new image to old card but then it got as far as "crng init done" then stopped.

i see what people are saying, i need new firmware - but how to get all the files in the right place ?

If repositories are not updated then you may try to create packages of kernel and bootloader from the fresh image as described here
https://askubuntu.com/questions/309527/ ... d-packages
then transfer them to old card and install both at once via sudo dpkg -i raspberry*.deb

EDIT: but maybe better wait as there may be more packages missing like newer wireless firmware etc.

[pi-man-uk1]

in the meantime though - booted with a fresh card to test the LAN wired network speed... yip. faster....

booted with a fresh card to test the LAN wired network speed... yip.

Your numbers are a bit low (would expect well above 300 Mbits/sec and also the count of retransmits is not that great -- I would check the network cable and run UDP tests in parallel) and unfortunately once the data that is transmitted over the wire lives on an USB disk we're bottlenecked even more by USB2: viewtopic.php?f=63&t=207897#p1285923

[pi-man-uk1]

interesting... i'll check the cables....

still good though I was logging the last lines of output before the upgrade (pi3 before).

so gone from 93 Mbits/sec to 284 Mbits/sec....

good to know that I could get a bit more though perhaps !

yes, not sure about those retransmits, wasn't seieng that on the old machine.

you were right... new patch cable (last one was home made, lesson learned).

new result...

well that was easy thanks... now only if I can get my old card booting !

Yes. You are looking in the Raspbian repo, not the Raspberry Pi repo. Look in http://archive.raspberrypi.org/debian/p ... -firmware/

Does anyone know the revision code for the 3B+ ?

Current documentation doesn't have it included -

https://www.raspberrypi.org/documentati ... /README.md

[hommar]

Update RPi HardwareHistory page, Please.

Add: Oops. I read previous message after writing this.

That's on ELinux - nothing to do with us. You could update that yourself!

That's been a problem ever since pre-loaded cards started being available. Companies--quite reasonably--want to move older inventory. The unfortunate thing is that such cards get sold without warning, and all to often to people who are unaware of the issue. I would look on a pre-loaded card as a convenient, but not necessarily inexpensive, way to get an extra SD card and immediately re-flash it with a current image.

Unfortunately all those 'pre-loaded' things are old and insanely slow SD cards being often 100 times slower than any recent and good A1 rated card. Talking of course about random IO performance with small block sizes here (IOPS). That's entirely what 'storage usage with Linux on SBC' defines, sequential performance (MB/s) is close to irrelevant.

Unfortunately the majority of SBC users is not aware of this, buys slow or even crappy cards and then suffers from sluggish board behaviour. Cards of the same speed class (irrelevant sequential performance, e.g. 'Class 10') can differ by factor 10 or even 100 when it's about the important random IO performance.

See Jeff Geerling's pioneer work on this 'issue': https://www.jeffgeerling.com/blogs/jeff ... crosd-card

See this 2018 update testing especially those new and insanely fast A1 cards: https://forum.armbian.com/topic/954-sd- ... ment-49811

Switching from an average SD card to such an ultra fast one is comparable to replacing a HDD in a PC with an SSD. Since random IO performance matters!

[pi-man-uk1]

just PSA with my earlier problems. About an hour ago I did sudo raspi-config, that updated stuff such that the old card booted fine in the new pi 3B+.

happy days, tks.

<looks at SD card bought with 3B+>
Well, it says 16GB A1 ... the files all have a datestamp of 14/03/2018 ...

Anyone know an obvious way (while looking via Windows - not booted it yet) to confirm I'm using the latest pre-loaded NOOBS ? Not that I'm planning on staying with it, but ...

So it looks like tkaiser may be being broad with his brush if The PiHut have indeed sold me a fast card with the latest image ...

[jamesh]

Can we keep the subject to the new B+ rather than performance testing of ancillary stuff.

Thanks.
