I have had internet working using the non meta-ti layer. Any tips suggestions
are highly appreciated.

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!

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/
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:

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 the following issue. I'm working w/ some Linux-based embedded system.
i create an image w/ my linux, load it to device and run. Everything was pretty cool till i added some 3rd-party modules. After this the loading was failed w/ the following stack:

i'm not sure that problem is w/ lack of room on device's flash memory. But anyway i can't figure out what can be the reason of this failure.
What is the reason of this failure can b?
The 'uname -r' returns the following:
2.6.36.4brcmarm
Let me know if anything else is needed.
Thanks in advance!
Well, it seems issue was fixed when i increased the size of file-system (-c parameter value during mkfs.ubifs call). Thanks for all help and suggestions!
