piCore-11beta wifi problem

[Juanito]

WiFi firmware or firmware in general?

[Paul_123]

This is wifi that I'm talking about.  But they have upgraded the several chipset firmware since launch.

I have installed firmware wifi without error.
What should I do to find wlan0 and scan nearby wifi?

Thanks

[Juanito]

Code: [Select]

$ tce-load -i firmware-rpi-wifi
$ tce-load -i wifi
$ sudo wifi.sh

This is content of onboot.lst on my piCore 11.X:

Code: [Select]

mc.tcz
openssh.tcz
libgcrypt.tcz
TC.tcz
firmware-rpi-wifi.tcz
dillo.tc
wget.tcz
wireless-4.19.81-piCore-v7.tcz
wifi.tcz


[Juanito]

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

[Juanito]

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:

Code: [Select]

$ dmesg
...
[    6.201902] bcmgenet fd580000.genet: configuring instance for external RGMII (no delay)
[    7.271857] bcmgenet fd580000.genet eth0: Link is Down
[   11.431873] bcmgenet fd580000.genet eth0: Link is Up - 1Gbps/Full - flow control rx/tx

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.

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.

[danny]

Is it possible that connect wifi which I have connected automatically after reboot rpi?

Thanks

[Juanito]

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".
