Re: Boot from USB mass storage fail using 'bootcode.bin' only with 'timeout' on SD

What kind of SSD is it? And are you using an adapter cable or enclosure? I've used similar JMicron 152d:0578 USB-SATA adapters with my Pi 3B before, and they worked fine. I have one USB 3.0 to SATA-III adapter cable, and an external mSATA USB 3.0 enclosure, and both work with my 3B (and 3B+). I do h...

Also, if you want the drive in /mnt you should mount it with /etc/fstab so the system will mount it the...

Re: Internet speed of Pi 4 and speed test from command line

In theory both the Wireless AC and Ethernet should be capable of Gigabit speeds. Wireless has more overhead, though, and of course there are range, interference and other losses to consider, so in actual use Ethernet will likely be faster. However, it also depends on your ISP speed. I'm only on 100M...

The Pi 4B has built-in WiFi, so why are you using a USB dongle?

Is it a USB 3.0 HDD, and is the WiFi dongle 2.4GHz?

Re: Raspberry Pi Zero: please use with a CPU cooler!

First of all, a Pi0 won't throttle until 80C, so if yours is throttling at 50C there is something wrong with it (damaged/going bad). Second, you can't glue a heat sink on the processor of a Pi0, since they use POP RAM. The SoC on the single core Pi models have the RAM mounted on top, so adding a hea...

That depends on the size of the card (larger cards are often faster), and it's not as simple as you make it seem. Class-10 by definition only requires a m...

Re: Problems using data from a USB stick

The first problem is the result of letting the system (file manager) auto-mount, and can likely be fixed by mounting the drive in /etc/fstab.

I don't have an answer for the second problem, other than, don't let the users remove the USB drive.

Re: My bluetooth doesn't seem to work

Did you change the audio output to the Bluetooth speaker? Right-Click on the speaker icon in the panel, and select the audio output device.

In my example picture below, the EDIFIER Exclaim Connect is my Bluetooth speaker, and if I select that I get sound through the speakers.

The only models that can boot from USB with no card installed are the 3B, 3B+ and 2Bv1.2. Older models can boot from USB by putting the boot-loader file bootcode.bin on a FAT32 formatted SD card, with the Raspbian OS on the USB drive. Contrary to some people's belief, that is true USB boot (everythi...

I do not think it is power related issue. These are the reasons for my statement: 1) It works with Raspberry Pi 3B+ board, which uses USB2 ports power (which is less than power over USB3 in Raspberry Pi 4B). Wrong. Raspberry Pi computers don't conform the USB power spec, so both the 3 and 4 have th...

Interesting topic. I had been naively assuming that fstrim would be happening automatically on SSDs. Should fstrim also enabled on SD cards? Depends on the SD card.

Having a monitor connected or not shouldn't affect the system booting. It may affect your ability to use VNC, but the system should still boot and be accessible using SSH. Most of my Pi computers are headless, and they all boot fine without anything except power connected. To use VNC with a Pi4 you ...
