Re: FYI: raspi-config not used in GUI

The raspi-config tool configures the Pi in the same way as the "first run" wizard you are talking about. The issue you have encountered is that unless you at least press "cancel" at the first opportunity in that wizard, it will start up again the next time the Pi boots. You can safely press "cancel"...

Re: Updated 64-bit Gentoo Image for RPi3 Released (now also for RPi3B+ and RPi4B)

That post refers to the old USB controller on previous models of Pi, not the new VLI chip on the Pi 4B. There are some issues with USB on the Pi 4B, but not the ones 6by9 referred to in that post. The VLI chip is much more capable than the old controller built into the SoC. (There also seems to be ...

Re: rpi-bootloader updates for Aug 19?

I am wondering if usb boot has been enabled for RPi4b. This statement from a Moderator as recently as two days ago, in response to the question "When can we expect USB boot for the Pi 4?

Re: Updated 64-bit Gentoo Image for RPi3 Released (now also for RPI3B+)

As this release comes early in the lifecycle of the RPi4, expect to find a number of bugs and issues with it! In particular, one major issue, (due, as I understand it, per this post by 6by9, to a lack of FIQ fast interrupt handling on aarch64) is that isochronous transfers over USB are likely to be...

I wasn't aware that the 4B doesn't suffer from this limitation. Good to know but can you provide a supporting link please. Which limitation do you mean?

Removing heat sinks from an old Pi

I've just taken an old Pi 1B rev 1 out of service as a temperature monitor. It's got heat sinks stuck onto the POP RAM, LAN9512 and linear voltage reg with tape.

Re: Any workaround for USB HUB STT?

It sounds like you may be hitting the limit of the total number of USB devices the Pi 3B+ can use at the same time. I'm not sure if changing to a multi-TT hub would help. If you want to try a multi-TT hub then I have successfully used the D-Link DUB-H7 revision B1 (https://eu.dlink.com/uk/en/product...

Try removing and re-seating the display ribbon cable at the Pi end, making sure it is inserted fully in the socket and there are no greasy fingerprints on the contacts.
