Re: USB Boot

I use the alternative approach on all my pi devices. I confirmed this weekend that the same approach works on the pi 4b 4GB. I'm in the more complicated situation because I use BTRFS. So, on the SD card I'm storing a boot partition for the purposes of loading an initramfs that has BTRFS support so t...

Re: Raspberry pi 4 external usb3 ssd drive

I'm using an Intel 1.8" SATA SSD which is rated at 3.3v 1amp. Works fine. Using a 1.8" to 2.5" conversion board. Stable, no random disconnects. With prior Pi over USB2, you would get random disconnects under load which is far from ideal if you running the OS from the drive. In read tests, I sustaine...

Re: USB boot working but unstable

You can also rethink your application need to determine if you can run the setup in read-only mode, at least for the operating system. On deployed systems prone to power loss, I've had great success making all the partitions on the SD and USB read-only. You can use overlay to capture writes to the f...

Re: Pi 4 + netbook or just get a pi-top?

Does that connection from the top on the revised version integrate a heat sink? Can't really tell from the photo. It is a combined heatsink + GPIO connection. I thought it powered the RPi via the micro USB but I was remembering wrong. It does it all through that heatsink/GPIO bridge piece. https://...

Re: Pi 4 + netbook or just get a pi-top?

follow-up: My Pi4 4GB arrived today. I thought I'd have an issue with the USB-C being that I forgot to order one of the micro-USB to USB-C adapters, and hearing about the nightmare around cabling, I was convinced I'd have an issue with the few USB-C cables I have. Turns out things worked well. Swapp...

Just to clarify, I have the pi top original. I wasn't aware they actually revamped how it connects in the revised version.

Thanks guys. I'm going to give the suggestions a try.

It started out as a rpi B wheezy a long time back, and been upgraded along the way, and OSMC + retropi added along the way.

Even intensive use of i/o will trigger overheating after some time (< 5 min). I done my testing without a case....

No wlan0 or wlan1 showing up on a new pi3. Even when swapping out SD card from another wifi-working pi3.

Tried enabling device tree (if it was ever disabled).

Any ideas. No errors in dmsg.

Re: RPi 3 - Very poor wifi performance

2.5A is the recommended supply for the Pi 3 because.. Pi 3.. takes 1.3A Pi 3 USB ports.. *CAN* take 1.2A So if you have nothing (or something small) on the USB ports, your requirement now becomes 1.3A for the Pi. None of this precludes any embedded, battery or driver board applications, I'm not sur...

My wifi latency/packet loss issue (only when using with SSD plugged in) was resolved by switching to a smaller micro usb cable used to power the pi 3. I have been using the official 12W PSU. It has improved the WiFi performance dramatically, but it's not perfect (compared to my Edimax USB dongle, w...
