Re: Raspberry Pi 4 VL805 firmware release 0138a1

And that you do, even though github is offering us designers beta firmware branches. The confusion started because someone didn't follow the normal "alpha", "beta", "release candidate", "production", "hotfix" pattern for naming things. Their somewhat wonky names have now become the norm for the 4B ...

Re: gzip: stdin: not in gzip format

Why are you using rpi-update? You're clearly not qualified to run with the beta/experimental kernel/bootcode as you'd know how to solve your problem.

What triggered your foolhardy use of rpi-update? What are you trying to acheive? What problem are you trying to solve by compiling strange modules?

I don't know how to find out the IP address. Most home routers keep a list of connected clients.

Re: Custom Pin for SPI?

You need four pins for SPI. There's SPI1 (/dev/spidev1.2) on GPIOs 19 (MISO), 16 (CE2), 20 (MOSI), 21 (SCLK). Otherwise if you want to use different pins you'll need to write your own device tree overlay based on https://github.com/raspberrypi/linux/blob/rpi-4.19.y/arch/arm/boot/dts/overlays/spi1-1c...

Probably not the same as you and me and the military define as "nightvision". Too many folks use that term for IR illumination rather than the use of a NVD (which is classified as a weapon in some parts of the world).

Re: Why Wifi Country = KR has wrong channel selection?

You need to post your question on the HostAP / WPA Supplicant mailing list at http://lists.infradead.org/mailman/listinfo/hostap (or check the archives there first).

The list of channels isn't defined by the RPF/RPTL folks, it's part and parcel of the WPA Supplicant package.

"UTC" (Universal Coordinated Time, in French) It isn't. The English speaking folks wanted to call it "Co-ordinated Universal Time". The French wanted to call it "Temps Universel, Coordonné". The Time Standards Committee chose "UTC" for "Universal Time, Co-ordinated" and "Universel Temps, Coordonné"...

Piping the output from cat into grep then into awk doesn't make sense.

awk '/MemTotal/ {print $2}' /proc/meminfo

Re: Error while doing apt upgrade on RPi3, why?

What happens if you try
sudo rm /var/cache/apt/archives/libssl1.0.0_1.0.1t-1+deb8u12_armhf.deb
sudo apt update
sudo apt dist-upgrade -y

That should pull a fresh copy of libssl1.0.0_1.0.1t-1+deb8u12_armhf.deb from the RaspiOS repository and replace the broken copy you've got.

Pull off the I2C wires (between the screen and pin#3 & #5 on your RPi). You only need power for the RPi official screen on any Raspberry with a 40-pin header.
