Re: I can´t boot from usb in pi 4

just to confirm, its still the "old" bootcode.bin from before (the old boodcode.bin that I used to "USB boot" my RPi1B+) or it is a "new version" bootcode.bin? No idea my 4B hasn't arrived yet. I'd start with the one from the latest Raspbian Buster then try the one from stretch if buster doesn't wo...

Re: PI 4 Compute module with pci-e?

As I read the spec, the only USB present is connected via PCIe, the single USB port avialable on older iterations of the SoC isn't present on the Pi4. The old USB controller is still present on the SoC. On the 4B it's connected to the USB C connector. That's good to know. Does that mean the 4B can ...

Re: Raspberry Pi 4 B - HDMI over USB-C

No, this is not possible. There is no route from the graphics system to the USB system for video. Hmm... USB-C port would appear to right out, since it doubles as the power connector, however... I have a Pi2B that drives a 10" adequately through some adapters off a USB 2 port (the native connection...

Re: How can i upgrade a pi3 SD card to pi4?

One issue that may catch you out with the upgrade is that the recommended /boot partition size is now 100MB, which is a bit larger than it used to be. It may cause problems during upgrades now or in the future if it isn't resized. I'd expect problems doing that. Last time I tried the library used b...

Re: PI 4 Compute module with pci-e?

A thought occurs: won't repurposing the PCIe lane of the Pi4's SoC mean no USB? As I read the spec, the only USB present is connected via PCIe, the single USB port avialable on older iterations of the SoC isn't present on the Pi4. So no device mode to flash the onboard eMMC. In fact, does the USB so...

USB boot is not currently supported on pi4. It's on the list for a future firmware update (unlike earlier models the pi4 has updatable boot firmware).
Will the "SD card with just bootcode.bin" trick that works on pre Pi3 modesl work on the Pi 4?

Well yeah. As a matter of course you should set unique hostnames for each pi on your network. You'll have difficulty accessing them by name if you don't.

That's difficult to say without more information.

Essentially you add a new line for the HDD you want to mount.

Reading the documentation for fstab and the mount command would be a good starting point.

Try

Code: Select all

man fstab
and

Re: Power on / shutdown RPI time or network

There's no sleep mode so no remote wake either. A shutdown pi with power can be booted by briefly shorting the run header or pulling GPIO 3 to ground. Both of which require external hardware. Be aware that a pi will continue to draw power (though much less) even when the OS is shutdown. I'd go for a...

That's expected behaviour. There is only one USB port on the SoC. It can do either slave/device mode (e.g. ethernet gadget) or host mode (ZERO4U) at a time. If dwc2 is loaded and in dual role mode it can hot swap but be aware that using a USB hub in this configuration will kill performance on the ze...
