Title: piCore-11beta wifi problem
Post by: danny on April 12, 2020, 10:29:28 PM
Hi
I can't find wifi on rpi3b+ in piCore-11beta
When I key "sudo /usr/local/bin/wifi.sh".
I got "No wifi devices found!".

This works for me:
Code: [Select]
$ tce-load -i firmware-rpi-wireless
$ tce-load -i wireless-KERNEL
$ tce-load -i wifi
$ sudo wifi.sh
Note that the firmware must be loaded first

I executed "tce-load -i firmware-rpi-wireless"
I got firmware-rpi-wireless.tcz not found!

Please refer this when I executed "uname -m".
armv7l
And then I executed "tce-load -wil firmware-rpi-wireless".
I got the following:

Sorry, my mistake, that should have been:

..it used to be called firmware-rpi-wireless in the 9.x repo...

Hi Juanito
I got the same message "No wifi device found!"
It seems unable to detect "wlan0".

Thanks

After some checking, it looks like the firmware for your hardware is present in firmware-rpi-wifi - I don't know why it doesn't load.
Title: Re: piCore-11beta wifi problem
Post by: Paul_123 on April 16, 2020, 01:12:14 PM
I supplied the firmware package for this.  And all wifi is definitely working.  Make sure the firmware is loaded before the kernel drivers.

Perhaps show us the contents of /mnt/mmcblk0p2/tce/onboot.lst
Title: Re: piCore-11beta wifi problem
Post by: Juanito on April 16, 2020, 10:27:21 PM
When you say "all wifi", does this include RPi4?

I'm having problems getting wifi (firmware) and hardware acceleration to work on an RPi4 - it seems something is not set up correctly in piCore-11.0beta1a as it looks in the armv7 rather than armv7l repo?
Title: Re: piCore-11beta wifi problem
Post by: Greg Erskine on April 16, 2020, 11:17:03 PM
I am not sure if Paul tests everything on the "official" piCore OS, but full support, including wifi, on piCorePlayer for the RPi4B happened a few days after it's release. From memory Paul did the development before he had a RPi4B, I did the RPI4B/wifi testing and have used it ever since.

I think Paul submits the wifi extensions back to Bela for piCore.

So wifi "should" work on piCore.

Thanks - using crda from piCore-10.x armv7, I get this:
Code: [Select]
cfg80211: loaded regulatory.db is malformed or signature is missing/invalid
..and whereas the RPi3 wifi still works with this error, on the RPi4 no wifi interface is created.
Title: Re: piCore-11beta wifi problem
Post by: Juanito on April 17, 2020, 05:36:06 AM
I downloaded a new copy of regulatory.db and the p7s file from https://kernel.googlesource.com/pub/scm/linux/kernel/git/sforshee/wireless-regdb but the error persists.

(I see /usr/local/lib/firmware is not valid for piCore)
Title: Re: piCore-11beta wifi problem
Post by: Paul_123 on April 17, 2020, 05:53:06 AM
Correct, the chipset looks in /lib/firmware, I'm not sure that can be changed.

I should have said I submitted that package back in earlier alpha versions of piCore11.   In its latest beta, Bela upgraded openssl,  I have not built crda against the latest openssl.

Let me take a look at it this weekend.
Title: Re: piCore-11beta wifi problem
Post by: Juanito on April 17, 2020, 07:05:34 AM
Thanks - am I right in thinking that the RPi4 WiFi won’t work without the Reg db?
Title: Re: piCore-11beta wifi problem
Post by: Paul_123 on April 17, 2020, 08:04:30 AM
There is a good chance of that.  But I can't totally remember.....I did most of this work with weeks of the 4B+ board coming out.

The other thing that "may" be required is setting country code.  Which wifi.sh does not handle today.  But country code is not what's keeping the interface from showing up.
Title: Re: piCore-11beta wifi problem
Post by: Paul_123 on April 17, 2020, 08:27:42 PM
Did some digging.  I would have to say that this is a kernel problem.  I verified I get the same messages as you with piCore11-b1.  So I moved to the piCorePlayer kernel.

Loaded firmware-rpi-wifi.tcz  (With crda not loaded)
Load wireless-KERNEL.tcz

I get this in dmesg, and the wlan0 interface is created.
Code: [Select]

then I rebooted, but before loading the drivers, I grabbed regulatory.db and regulatory.db.p7s from git.kernel.org/pub/scm/linux/kernel/git/sforshee/wireless-regdb.git and put them in /lib/firmware.

Then loaded wireless-KERNEL.tcz

And the interface is created.  I did not load the full crda, so that has nothing to do with it.
Title: Re: piCore-11beta wifi problem
Post by: Paul_123 on April 17, 2020, 09:21:06 PM
I got through all this and I realized I never checked the firmware md5 against my copy.   The firmware extension in the TC repo has something wrong with it.  If I use the pCP firmware package on piCore11,  then the driver loads.

There is still a problem regulatory.db, which I'm not sure what's going on there.


oh, BTW, if you look at tc-functions, you will see its pointing armv7l to armv7
Title: Re: piCore-11beta wifi problem
Post by: Juanito on April 17, 2020, 09:51:53 PM
That's good to know - could you point me to the correct pCP firmware so I can rebuild the piCore firmware extension.

Ref tc-functions, I knew there had to be a problem for RPi4 somewhere...
Title: Re: piCore-11beta wifi problem
Post by: Juanito on April 18, 2020, 12:24:21 AM
I managed to get hold of the pCP firmware-rpi-wifi extension and wifi now works on the RPi4 without the reg db or crda.

Better still, the RPi4 can see both 2.4 and 5ghz access points  8)

I'll post the pCP firmware-rpi-wifi to the piCore 11.x repos without the crda dep for now.

..and now to attack hardware acceleration for the RPi4...
Title: Re: piCore-11beta wifi problem
Post by: Paul_123 on April 18, 2020, 06:00:25 AM

You can remove wireless-4.19.81-piCore-v7.tcz from onboot.list since it is a recursive dep of the wifi extension.

You also need to update the firmware-rpi-wifi extension as it was modified recently.

Hi Juanito
When I partition disk of piCore11.X, I can't reconnect  network by Ethernet.
How can I solve this problem?

Thanks
Title: Re: piCore-11beta wifi problem
Post by: Juanito on April 24, 2020, 03:49:54 AM
What I see (with a gigabit ethernet connection) is that it takes about 5 minutes after reboot before I can ssh into an RPi4 running piCore-11.x.

With an RPi3 running piCore-11.x it takes about 20 seconds.

You can see here that it's taking a while to get going:

I also can't connect to network by Ethernet after waiting 20 seconds.
Is it possible that partition disk on piCore happen some problem?
I followed this web to partition disk.

Post by: Juanito on April 26, 2020, 10:17:18 PM
If piCore boots to a console prompt I'd guess that the problem is more likely to be with the RPi and/or its firmware.

As said, using an RPi3 with piCore-11.x takes about 20 seconds before ssh connects whereas an RPi4 with piCore-11.x takes 5 minutes - and this is using the same sd card and same network cable.

I'm not sure whats going on with piCore11, as our 4.19.y based systems become responsive must faster than that.  My initial suspect is something with openssl.    I wonder if it is setup using a blocking call to random?

Might have to install rngd to see if that helps.

Yes:

* add firmware-rpi-wifi and wifi to onboot.list
* add wifi.sh -a 2>&1 > /tmp/wifi.log to /opt/bootlocal.sh
* make a backup (this will save bootlocal.sh and ~/wifi.db)

I install piCore on compute module 3.
I want to share my PC network to it by USB to Ethernet cable.
But I don't see Ethernet interface when I execute "ifconfig".
