Re: Raspberry Pi 4 Thread - general discussion

From https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2711/rpi_DATA_2711_1p0_preliminary.pdf The Pi4B has a dedicated SD card socket which suports 1.8V, DDR50 mode (at a peak bandwidth of 50Megabytes / sec). In addition, a legacy SDIO interface is available on the GPIO pins. can som...

Re: Is there any way I can use both my physical switch and my relay simultaneously

The only problem with that is the amount of noise on the cable between the press-to-make switch and the Raspberry. we had something like that with ESP8266 (hidden under nice old ceramic switches) combined with a (hijacked) philipps hue system (there are nice bindings to node red available). The bes...

Re: What is a good replacement for Etcher (ads and ignores privacy)

I respectfully disagree with you, in terms of verification being the most important. If for example, we assume Etcher did not exist but there was an Etcher like tool that did everything but verification and a manual Linux/Windows/MacOS command line method that included verification, for new folks I...

lol.. so much garbage for only two words. On linux there are a bunch of tools.. even dd, but I still use Etcher. And the whole point of using etcher is image verification (if there's a tool which uses less resources, etcher generates 'a lot of load' for a simple job, I would happily switch). (Some) ...

Re: What is a good replacement for Etcher (ads and ignores privacy)

The whole point of recommending Etcher is it mostly idiot proofs the process so at least a new person gets a working SD card that has a good chance of a successful first boot. Another big win is that it can be done from the "safety and comfort" of the Windows computer they most likely have and at l...

Re: Increase /boot Partiton?

not that I support the approach of using /boot as an 'storageplace' but why not just create an Raspbian with an extended fat partition during image creation (I would rather prefer a raspbian without any fat partition at all - won't happen and different story at all)? e.g. https://github.com/RPi-Dist...

Re: 64 bit Ubuntu 18.04 on Pi4B

likely that it tries to update the kernel as well? you probably should freeze the kernelpackage (apt hold ...) to ensure it doesn't mess around?

Btw. does the RPT plan to maintain a 64bit kernel on one of your repositories? At least you maintain a 64bit kernelconfig.. so it won't hurt you much.

Re: USB to m.2 on pi 4

To get higher 10Gbps speeds you would need an NVMe SSD and a USB 3.1 Gen 2 NVMe enclosure (expensive) and, of course, you'd need a USB 3.1 Gen 2 device to plug it into. The whole chain (drive, enclosure, cable and device) all have to support the faster standard. Or you opt for an SBC which just off...

With the recent changes, e.g. boot binary yet on SPI flash, do we have a chance to get the new RPi booted from ext4 directly? For those want to argue about pro and con of such an approach, I'm not interested in this discussion. ;)
