@ patrikg:  thank you so much for your detailed explanation.

I'll have to study a bit.

Hi bradwiggo

... Why doesn't it work when I manually load them? ...

Try it like this:

Code: [Select]

tce-load -i firmware-ralink
tce-load -i wifi
Or like this:

Code: [Select]

tce-load -i firmware-ralink wifi

The firmware extension needs to be loaded first.

You can check with dmesg if the firmware has been found and loaded.

Hi bradwiggo

... Tried the `firmware-ralink` and `firmware-mediatek`, neither seemed to work unfortunately

They both contain the firmware for your device. Keep the firmware-ralink
and remove the firmware-mediatek. The ralink extension is much smaller
than the mediatek (41K vs 9.3M).

... Using `wifi.sh` says no wifi devices found, ...

Do you have all of the dependencies for wifi installed:

Code: [Select]

wireless_tools.tcz
wireless-KERNEL.tcz
regdb.tcz
wpa_supplicant.tcz
libnl.tcz
openssl.tcz
ca-certificates.tcz
readline.tcz
ncurses.tczwireless-KERNEL.tcz  contains the driver for your device (mt7601u.ko).

You need the .tcz, .tcz.md5.txt, and the .tcz.dep (if it exists) files for each extension.

I didn't have the dependencies installed properly before, I'd forgotten the .dep files. However it's unfortunately still not working. The WiFi adapter still isn't showing up. ifconfig doesn't show any "wlan0" device

dmesg shows the following:

Code: [Select]

mt7601u 1-1.2:1.0: ASIC revision: 7610001 MAC revision: 76010500
mt7601u 1-1.2:1.0: Direct firmware load for mt7601u.bin failed with error -2
mt7601u: probe of 1-1.2:1.0 failed with error -2
usbcore: registered new interface driver mt7601u

Edit: It works if I put the .tcz files in onboot.lst. Why doesn't it work when I manually load them? They are at the bottom of onboot.lst, so surely there should be no difference

You can figure it out your self with some knowledge how the systemcalls being used in Linux.
You can use strace for example like this.

Code: [Select]

strace -e openat gnome-terminal 2>&1 | grep -v 'ENOENT' | grep confExplanation of that line.
1. Run strace.
2. Just watch the openat systemcall.
3. Run gnome-terminal.
4. Put standard error to standard in because strace puts it output to standard error.
5. Pipe strace output to grep.
6. Grep revers of the 'ENOENT' to get what files being loaded, not the files that get not found.
7. Pipe to grep.
8. Grep for conf like config.

What I can see is that gnome-terminal uses dconf to store it's config in my system you can list the settings like this:

Code: [Select]

dconf dump /org/gnome/terminal/legacy/profiles:/

Last question, please: where are the gnome teminal settings stored?

I'm unable to find them. Many thanks

Minor Update:

• OPi is now connected to an ATX (1U) power supply using 5vSB (purple PSU wire) inside a $30 Mini ITX computer case which had a 150w power supply included (see photo)
• GPIO is being used to turn the power supply "on" which launches fans, HDDs, etc. (green PSU wire)
• Mini ITX to OPi mount built to create an I/O plate on the rear of the case and even a small "tube" for the WiFi antenna to hide in
• 5015 Turbine/Centrifuge Fan added to cool top and bottom of board (38 degrees was the max at 100% CPU) - tiny bit noisy, but expected due to size and type of cooling fan
• USB-C power connection bypassed by utilizing the *FAN* header and used as 5v DC INPUT (from any RED PSU wire.)
• Power and Reset buttons will need to have wired headers soldered on to them to utilize the case's front buttons
• GPIO pin(s) might get used for the case's front LEDs and HDD LED assigned to sys/class/leds for displaying "activity"
• RTC battery adapter (with on/off switch) implemented to keep time
• 6 Port SATA M.2 board temporarily connected to top socket to test SATA capabilities/throughput

I'm about 1/3 of the way of putting a sane kernel config together to accommodate TCL's way of doing things, we have about 75% of the toolchain apps gathered and set up, cross-chain built and tested for kernel, u-boot and SOME of the apps needed for our foundation (still a ways to go), graphics binary/blob is now in our archive, but still being investigated and wireless is still being looked into as we found a few weak spots/bugs while testing the cross-compilation environment and technical support at the factory...  less than ideal.  (No response to my last handful of emails once moneys had been exchanged.)  I don't want to get TOO carried away with compiling just yet as I want to test a number of build scripts on the RISCV board and also through the cross-compiler environment to make sure we can accomplish everything in a more automated fashion.

If anyone wants to lend a hand, go to our project's Git Hub and read the page's info, then take a look inside the "final" directory for a few examples of working (tested under ASH thus far) builder scripts.  Initially, we will want and need virtually anything compiler/linker/library related. Take a look at one of the existing builder scripts in ./final, it should be reasonably easy to follow.  For go_version() there are going to be plenty of people who can code in C in their sleep, but "web" anything isn't in their wheel-house.  For anyone wanting to help but not sure how to scrape information from online resources, simply have go_version() return the word "unknown" and we'll tend to version scraping for you.  (Be sure to fill out SRC_SITE="" so we know where to look!)

Hi bradwiggo
Welcome to the forum.

The first thing to do is run lsusb provided by usbutils.tcz. That will
allow you to post the VID:PID (xxxx:yyyy) of the device so its
chipset can be identified.

Code: [Select]

Bus 001 Device 004: ID 148f:7601 Ralink Techology, Corp. MT7601U Wireless Adapter

Same output when plugging the adapter into my laptop

Tried the `firmware-ralink` and `firmware-mediatek`, neither seemed to work unfortunately
