Get 3.10.65-3-pine64-longsleep-2 from https://www.stdin.xyz/downloads/people/l...ges/linux/

Update like this (as root) on any of my images:

Code:
bash <(curl -s https://raw.githubusercontent.com/longsleep/build-pine64-image/master/simpleimage/platform-scripts/pine64_update_uboot.sh) bash <(curl -s https://raw.githubusercontent.com/longsleep/build-pine64-image/master/simpleimage/platform-scripts/pine64_update_kernel.sh)

If you update U-Boot as well you will get automatic Pine64 model detection, making the image also work with networking on the non-plus Pine64 automatically when you remove the fixed dtb filename from the existing /boot/uEnv.txt.

Image works like a charm on 512mb model.
As for the ethernet functioning:
Iperf3 between Pine+ (server) and Pine (client)

[ 4] 0.00-30.00 sec 337 MBytes 94.2 Mbits/sec receiver

two boards connected to same gigabit switch.

That's great that it's working! Just for comparison, also using iperf3, using a windows desktop with GigE and pine64+ I get:

664 Mbit/s with pine64+ as server
371 Mbit/s with pine64+ as client

Thought it was interesting that there was asymmetry. Perhaps CPU bound?

check out the post:

and how multithreading affects it.

Hi, sorry if I'm crashing thread with unrelated topic, but with a linux OS on Pine64, does that mean wi-fi/BT USB dongle will work? It's taking forever for the wi-fi/BT daughter board to be released and the store opening date is unknown at this point. Thanks!

New member! I've tried to read up before posting my question.

I just received my new Pine64, installed the base system and kernel (thanks longsleep!) and booted just fine. Video was wonky, but that's apparently known.

I saw an updated kernel available, as well as the updated uboot, so using the method above I went ahead and installed them.

Well, i didn't get far, because I couldn't boot anymore.

After hooking up a serial console (hooray for my BusPirate 4.0!) I saw that uboot wasn't able to boot the new kernel.
I was able to boot the old kernel manually, and set out to find out why.

Here's the old kernel that boots just fine:
root@p64:/boot# od -xa old/kernel.img |head
0000000 4e41 5244 494f 2144 30c0 00c9 0000 4108

nul nul nul nul nul nul nul nul nul nul nul nul nul nul nul nul

And the newly installed kernel:

root@p64:/boot# od -xa pine64/Image |head

0000120 0050 9400 0016 d538 03e0 aa16 0121 9400

So, the magic at the beginning of the file is different. Too different apparently for uboot?

here's what my environment looks like, using the new kernel:

boota: bad boot image magic, maybe not a boot.img?

is this a *me* issue that I can correct with some uEnv tweaking, or something different?

*** edit

there's 2059 bytes of 'header' at the beginning of the old kernel image that's not on the new Image.
transplanting this header creates a file that is recognized, but doesn't work (presumably it doesn't have the right offsets, or some other data)

@longsleep correct me if I'm wrong Smile

I think you have a uboot / kernel mismatch. The latest image provided by @longsleep should boot using booti and kernel does not require the Android magic header.

For the previous message in the thread - the Linux image supports the WiFi part of that adapter, I am not sure about the bluetooth.

patrickhwood · 03-31-2016, 08:49 AM

If your boot script is using boota in boot_kernel; boota expects an android image with the ANDROID! magic header, so looks like you're either using an incompatible uboot or perhaps boot_kernel should be reset by uEnv.txt but isn't.

longsleep · 03-31-2016, 10:42 AM

Maybe you have saved the environment uboot.env with the old settings. Remove that file. If thats not it, you u-boot update did not work and you should try again.

Ah!

I removed the uboot.env, forced a u-boot update, made sure my uEnv configs were correct and reboot.

this time, the new -3 kernel booted.

That looks very much like the ethernet issue that we are talking about over here: http://forum.pine64.org/showthread.php?tid=376&page=6

You have an ethernet cord plugged in? And do you have the 2gb version?

Found the issue. Fixed in https://github.com/longsleep/linux-pine6...6021a4484f - will release a new Kernel build today.

I pushed a new Kernel build, fixing the Ethernet crash for 2GB Pine64+ models.

Get 3.10.65-4-pine64-longsleep-16 from https://www.stdin.xyz/downloads/people/l...ges/linux/

Update like this (as root) on any of my images:

Code:
bash <(curl -s https://raw.githubusercontent.com/longsleep/build-pine64-image/master/simpleimage/platform-scripts/pine64_update_uboot.sh)
