I have a Raspberry 3 Model B which has a BCM43438 wireless LAN and Bluetooth Low Energy (BLE) on board and recently installed Ubuntu 20.04 LTS. Thanks in advance for looking and let me know if Ubuntu 20.04 on RPI3 does not support wifi at this time.
I've read a few posts saying look for the /etc/network/interfaces file but I have no such file on the computer:
ubuntu#ubuntu:/etc/network$ ls -laFioh
total 32K
767 drwxr-xr-x 6 root 4.0K Dec 3 16:18 ./

775 drwxr-xr-x 2 root 4.0K May 23 23:08 if-up.d/
When querying the hardware I get the following:

Here is (edited for post length) dmesg:

I am trying to use the PCF85063A RTC device on a Toradex Colibry i.MX7D processor.
Used Setup:
Colibri iMX7D 1 GB V1.1A
Kernel 5.4.161-5.6.0-devel+git.0f0011824921
For this, I created an own DTS file. Here’s the relevant DTS change:
&i2c4 {
status = "okay";
/* PCF85063A real time clock on carrier board */
pcf_rtc: pcf85063a#51 {
compatible = "nxp,pcf85063a";
reg = <0x51>;
interrupt-parent = <&gpio1>;
interrupts = <1 IRQ_TYPE_EDGE_FALLING>;
wakeup-source;
};
};
I enabled the driver in the kernel configuration, recompiled the kernel and modules and deployed them.
CONFIG_RTC_DRV_PCF85063=y
The output of dmesg after booting the system is as follows, which looks good to me at first glance:
~$ dmesg | grep rtc
[ 1.071396] rtc-pcf85063 3-0051: wake irq already initialized
[ 1.293186] rtc rtc0: failed to enable irq wake

But one block within dmesg output makes me think that something is wrong initialized:

Then, when using the RTC device several times, everything looks good.
~$ echo +10 > /sys/class/rtc/rtc0/wakealarm
I can see, that changes to the alarm are reflected in the corresponding registers (it works as expected).
~$ i2cdump -f -y -r 0x0-0xf 3 0x51 b
0 1 2 3 4 5 6 7 8 9 a b c d e f 0123456789abcdef

I can repeat this commands as much as I like… …but when I enter the suspend mode, the behavior changes!
~$ echo +10 > /sys/class/rtc/rtc0/wakealarm
~$ systemctl suspend
After the 10s, the system resumes. But now, I am no more able to activate a new alarm:
~$ echo +10 > /sys/class/rtc/rtc0/wakealarm
-sh: echo: write error: Permission denied
And dumping i2c device looks very strange…
~$ i2cdump -f -y -r 0x0-0xf 3 0x51 b

Can anyone help me to get the external RTC running also after a suspend/resume change? Any help would be greatly appreciated.
Cheers
Update:
I am aware that both the internal (snvs_rtc) and external (PCF85063) RTCs are used. It would be enough to use only the external RTC, but I have not managed to disable it. When it is disabled, the system no longer boots and this last dmesg message appears:
[ OK ] Mounted /var/volatile.
Starting Load/Save Random Seed...
[ 6.396724] systemd-journald[173]: Successfully sent stream file descriptor to service manager.
[ OK ] Started udev Kernel Device Manager.
[ OK ] Started Load/Save Random Seed.
I have disabled it with following code in the DTS:
&snvs_rtc {
status = "disabled";
};
This part from dmesg you claim is good is actually not:
[ 1.071396] rtc-pcf85063 3-0051: wake irq already initialized
[ 1.293186] rtc rtc0: failed to enable irq wake
Which is the warning splat you get in the full dmesg.
Are you sure about the RTC interrupt being connected on gpio1 1? It seems this GPIO is already used as a wakeup interrupt by another driver.
Note that the wakeup-source; property is not needed when you have an interrupt defined.
I have am335x related customized board and kernel(4.4.16) source code
I configure the FTDI module driver. so after kernel start successfully I attach ftdi converter to usb port and then type lsmod command to check module list

As you can see in the dmesg output:
[ 5.379690] usb 1-1: New USB device found, idVendor=10c4, idProduct=ea60
Looking that up, e.g. here:
https://www.google.com/search?q=usb%20vendor%20id%2010c4
Tells you that it's a "Silicon Labs" USB device, who also make the CP2102.
The log does not identify other devices (ignore the linux kernel root hub).
So either you have also a CP2102 attached (and the FTDI is not properly connected) or the device you think is a FTDI based device, is not.
In addition you can identify currently enumerated devices using the lsusb command.
The automatic loading is usually done by udev or a similar user space daemon/mechanism. A decent explanation can be found e.g. here: https://lwn.net/Articles/740455/
Problem: Linux can successfully hibernate to swap partition (/dev/mmcblk0p11) by echo disk > /sys/power/state, but can not resume from this partition.
Linux version: 4.9.110

The reason seems like PM can not found the /dev/mmcblk0p11 when system booting.

What I found is that the mmc has not ready when PM try to resume. PM try to resume at line 2, but mmc start init at line 22.
What I did for trying to fix it.
1. add resumewait to Kernel CMD line, the result is kernel will endless wait mmcblk0p11 ready.
On my embedded system there is a Real Time Clock (RTC) connected to uart 2.
21e8000.serial: ttymxc1 at MMIO 0x21e8000 (irq = 59, base_baud = 5000000) is a IMX
I have written a rtc kernel driver that uses filp_open("/dev/ttymxc1", O_RDWR | O_NOCTTY | O_SYNC, 0) to communicate with the RTC. After I boot and log in everything works great. hwclock does what it is supposed to. The problem is during boot the filp_open returns a -2 /* ENOENT - No such file or directory */.
silhouettestar2_rtc rtc.24: RTC-SilhouetteStar2: file open error = -2
My rtc_read_time function is getting called twice during boot and both times the same error is returned. Dmesg is showing me the uart drivers are loaded before the RTC driver. I have the suspition that ttymxc1 is not enabled yet. Can ttymxc1 get enabled when the driver is loaded like the console? Is there another interface that can be used in the kernel module to communicate directly with ttymxc1?

I have had internet working using the non meta-ti layer. Any tips suggestions
are highly appreciated.
Auke
Your distro appears to not have ipv4/6 configured, hence BusyBox drops all networking from its config. I'd say to do DISTRO_FEATURES += "ipv4 ipv6", but it's normally the default... Looking closer at your config above, you simply overwrite all the defaults with DISTRO_FEATURES = "wifi", while you probably want DISTRO_FEATURES += "wifi" instead - to append, not overwrite...
Reading through /var/log/messages I was notified on the BusyBox version, checking the configuration I noticed that the default configuration has ipv4/6 disabled.
(Pff why?)
In order to fix it:
bitbake -c menuconfig busybox
bitbake busybox
check all settings!
