Cannot see any Wifi networks on rPiZeroW
atomant:
Hello great communitiy of tiny core!
I'm trying to connect a Raspberry Pi Zero W to my Wifi network using it's built-in adapter. I have downloaded piCore 9.0.3, burned it onto SD card, etc, had no problem with the installation. Once TCL was up and running i downloaded wifi.tcz and firmware-rpi3-wireless.tcz (and dependencies) on a PC onto the card (i created a third partition to be used to carry files inbetween rPi/TCL and the PC/Win), booted into TCL again and copied the needed tcz-s to /mnt/mmcblk0p2/tce/optional, used tce-load to load firmware and then wifi.tcz and they loaded without any problem (got all OKs). Added these to the bootlist.txt, rebooted TCL and then ran wifi.sh. And the problem starts here, i can see no Wifi networks whatsoever, nix, nada, zero. I cannot see any obvious errors either.
I can see the firmware getting loaded if i check dmesg (or at least i guess that's what this means):
--- Code: (bash) ---[ 16.581329] usbcore: registered new interface driver brcmfmac
[ 16.835064] brcmfmac: Firmware version = wl0: Aug 7 2017 00:46:29 version 7.45.41.46 (r666254 CY) FWID 01-f8a78378
--- End code ---
If i do iwconfig i see this:
--- Code: (bash) ---wlan0 IEEE 802.11 ESSID:off/any
Mode:Managed Access Point: Not-Associated
Retry short limit:7 RTS thr:off Fragment thr:off
Power Management:on
--- End code ---
if i do
--- Code: (bash) ---ifconfig wplan0 up
--- End code ---
i get no error, if then i do
--- Code: (bash) ---iwlist wlan0 scan
--- End code ---
it says "no scan results". (Ran these as root.)
What i'm sure of:
-there are plenty of wifi networks around, next to my own i can see plenty of the neighbours' networks on my PC, on my phone, on tablets, ...
-my router's wifi is up, i'm using it right now on PC to submit this cryout for help
-the rPi has Wifi, it's the W version (it's written on it), i know the earlier versions of the Zero had no on-board Wifi but this is not one of those.
-i have both 2.54Ghz and 5Ghz networks available, rPi sees none
What i tried so far (with no success):
-using 9.0.2 of Tiny Core
-going the wpa_supplicant way to connect to my wifi (i spent many hours tweaking the config trying to get some result but nothing)
-using another rPi Zero W (so i suspect it's not a hardware problem, unless i have 2 identically faulty boards)
Notes:
-i'm not using any GUI, everything's done on terminal
-rPi is running off an 5V power supply which can output 2.25A, i'm not absolutely sure but i doubt the pi is underpowered
-the only things connected to the pi are an USB keyboard and a TV set trough HDMI
I'm stuck at this, i have no idea what i might be doing wrong. Pointers, suggestions are welcome.
P.s: i read on a non-TCL specific forum (i think it was raspbian?) that the wifi chip has to know what region/country/whatever you are in because available (legal?) Wifi signals might be different depending on this and the chip will simply miss the ones that it thinks are not present depending on it's location. I have no idea how substantiated this is and where you might find such a setting in TCL.
Thanks for reading and any help any of you can provide.

hi atomant,
I assume bootlist.txt is really onboot.lst ?
The country code is not necessary atm.
wpa_supplicant.config is overwritten from data in wifi.db
Did you download and install the .dep files as well as the .tcz? These files install the dependencies for extensions defined in onboot.lst. For exmaple, you define wifi.tcz in onboot.lst and wireless_tools.tcz, wpa_supplicant.tcz etc will be installed.

FYI: We have been using wifi on RPi0W with piCorePlayer since its release so all the bits are there.

[EDIT]: Fixed typo. Changed "install the .def files" to "install the .dep files". Rich

Hi Greg Erskine
I edited your post to fix a small typo.

Yes, sorry.

As far as i can tell, yes. I used this link: http://ftp.nluug.nl/os/Linux/distr/tinycorelinux/9.x/armv6/tcz/ and got everything (tcz, dep, txt, list, tree, whatever else there is) for the following packages (in random order):
wpa_supplicant, firmware-rpi3-wireless, readline, wifi, wireless-4.9.22-piCore, wireless_tools, libiw, libnl
and added them to tce/optional (i also considered ca-certificates but it was already there in tce/optional so i left that untouched)
As said, i used "tce-load -i firmware-rpi3-wireless.tcz" and then "tce-load -i wifi.tcz" on the command line before adding these to onboot.lst to see if i get any error but got all OKs (it listed the packages it loaded with OK as you might have guessed) so i assumed that i have everything that's needed available. Is that assumption incorrect?

I know, that's one reason why i don't get why it doesn't work for me, i must be doing something wrong but can't figure out what.
