documentation

Not only that, it's also Open Source Hardware. You can find all the design documents here: https://git.beagleboard.org/beagleplay/beagleplay Unlike RPi: https://github.com/raspberrypi/documentation/issues/2233 "The Raspberry Pi is not open source. However, reduced schematics are made available on a best efforts basis."

It would be nice if they where an open source hardware company. They don't publish the full schematics of anything, which makes it impossible to do low level programming of the thing in a reasonable manner. I'm going to use up the hardware I bought in ignorance, and find better stuff for the future. https://github.com/raspberrypi/documentation/issues/347

Yes, I have a Pi4 booting off a SSD on a USB-SATA bridge. No SD card installed. This graduated from beta about a year ago. [1] Btw, since you brought up USB: disable UAS [2] when using cheap USB-SATA bridges! UAS is regularly recommended for performance reasons, but I've gotten block-level errors (eg those below) and filesystem corruption with UAS multiple times and never with UAS disabled. I've seen enough similar reports on the Internet to think it's better to just disable UAS.

I am using mine as a DHCP, DNS, and VPN server. Something I've noticed is that the SD card corrupts easily, though that may be simply because I'm using a phone charger as the power supply. I discovered that although the Model B does not support natively booting off USB, you can still put an updated bootcode.bin [1] on the SD card which will enable this functionality. Hopefully my flash drive will not corrupt as easily. [1] https://github.com/raspberrypi/documentation/blob/master/har...

Thanks for your kind words. Don't be afraid to build your own. With the magic of libraries or tools a build script for your use case might just be a couple of lines. A great real-world example is the Raspberry Pi documentation website build script [1]. Cheers. [1] https://github.com/raspberrypi/documentation/blob/master/Rak...

TIL there's even a PXE boot option on the Pi 3, and several other boot modes as well. https://github.com/raspberrypi/documentation/tree/master/har...

For people not familiar with the industry or the issue, compare the documentation available for the broadcom processor in the popular raspberry pi 2 https://github.com/raspberrypi/documentation/tree/master/har... and that of the Allwinner A64 in the far less common "Banana Pi": https://github.com/OLIMEX/OLINUXINO/tree/master/HARDWARE/A64... As you can see, the Broadcom documentation is non-existent, with the exception of a tiny document created by a third party.
