Re: RPi as virtual PDF printer hooked up throughout USB ?

The Pi can print to PDF using the cups-dpf package, but the only ones that can be used as a USB device are the Zero range, the A models and possibly the Pi 4. Even so, I don't think any of them can emulate a printer via USB. Over a network it should be easy. Making a Pi Zero appear to be a USB stora...

Re: Which SSD to buy for raspberry pi?

Just too add that I have an unbranded USB 2.0 to SATA adaptor that is booting fine with a 120GB Palit SATA3 SSD on a PI 3B+. The chipset identifies as "Super Top M6116 SATA Bridge". It's one of those adaptors that has two USB connectors for extra power, but I only use the main one.

Uhhh I intaled on vm _ like just go to raspbarry and download the desktop os and set the setting to 8 cores and 4 gb ram dan 30 gb Hdd and set is in deabin8.0/64 bit
That would be interesting as the Raspberry Pi 4B only has 4 cores.
Also it runs Raspbian which is based on Debian 10.0/32 bit.

Re: cannot run a tensorflow docker image on Pi 3 B+

You'll probably find that the tensorflow docker image is for x86 CPUs only. You'd need an armhf image to run on a Pi.

If there is a Dockerfile available you can probably build your own image on the Pi, which should work.

Re: 32bits Linux OS on Raspberry Pi 3 B+

Yes. Raspbian is 32 bits.

But if you are planning to run i386 32 bit software on it, like for a PC, that won't work. The CPU type is wrong. PC is Intel or AMD and Pi is ARM. They use different instruction codes.

Well, an amd64 file isn't going to work on a Pi. As they don't seem to supply an armhf version of the file, the only option is to download the Source Code and build that. It should come with some instructions.

Re: Green LED constant blinking on rpi 4 without a boot sd card

If the green LED is blinking in a four flash pattern, that is normal. It means the bootcode is present in the eeprom, but no SD card was detected.

The Pi 4 is different to earlier models where the initial bootcode.bin had to be on the SD card. Now it is stored on the board.

Re: apt-get update/upgrade literally broke post Buster install

Somehow you have made a change that makes apt try to down load PC versions (i386) of the software instead of the Pi versions (armhf).

Can you post the contents of the files you changed in /etc/apt/ ?

Also, at any time have you done any dpkg commands that might have mentioned architecture?
