Re: [PI4:] how do I move the filesystem to a USB stick/Drive

Let us know what you'll find as the adaptator of your dreams. Good luck at hunt.
The point is that only this quirk allowed my Pi4 to boot with rootfs on the external drive. Maybe a Pi issue rather than an adaptator one. It works seamlessly for additional drive (IIRC) or with windoz

Re: [PI4:] how do I move the filesystem to a USB stick/Drive

I've just this minute figured out why it wouldn't work.... So, found out that it would work using the PARTUUID method as per the guides etc but only when plugged into the USB2 socket.

Pi4 raspbian buster : minissdpd fails to start on boot

Hi everybody I need to punch a port forward in the dsl-router behind which I'll drop my headless pi, for ssh access. As I'd rather like not to deal with port-forward in this router, I assume at a first glance it has uPnP enabled, so I first installed miniupnpc then later minissdpd . Also I'd rather ...

Make syslog lighter

Hi I have a software that fills my Pi log too much with ip connections tracking and a script I wrote that I would also startup not logged by cron. I searched around and read rsyslog would be configured by other files than /etc/rsyslog.conf . I have a file /etc/rsyslog.d/20-ufw.conf , so I created an...

Can't Reboot from pishutdown GUI after renaming pi user

Hi This is with latest raspbian and pishutdown 0.11 I didn't check for shutdown, only reboot, because the pi is remote ATM and no easy way to wake it up back.

Hi Dougie Thanks for reply. Even I didn't understand it helped me to guess a solution by looking with more attention to the ps output below. I'm not sure I understand.

Hi I wanted to compare pgrep -c ssh to a static number to prevent my Pi from shutdown by cron script.

Re: HOT Raspberry Pi 4 - 4GB

The good point for the flirc is it is a very good mechanical stand (path from SoC case to ambiant temperature) to attach another heatsink if we need more passive cooling. See my tweak above.

Re: Which SSR type to drive the official RPi4 wallet supply ?

2. Regarding switching off, if the SSR in off-mode is passing enough power that the oscillator in a switched mode PSU is oscillating then the SSR is, in my book, not off. You're right, I gave a try and the leakage current was enough to make the PSU to reach 5V on its output roughly every 20s which ...

When I first setup my Pi I had many things to change so I did it step by step (newb).

Which SSR type to drive the official RPi4 wallet supply ?

Hi What type of SSR should I select ? A synchronous one (i.e. zero-cross) or generic asynchronous? Did the designers perform any tests with this (required min/max rated current, maximum off-state leakage current to prevent the wallet to feed the Pi even when off-state) ? My goal is this : assumed th...

It won't boot OOTB even with the quirk. You'll also need to adapt /boot/cmdline.txt this way: usb-storage.quirks=152d:0578:u dwc_otg.lpm_enable=0 console=tty1 root=PARTUUID=8f4f4a26-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait And maybe also /etc/fstab (but this I'm not really sure)...

PS : a reminder : the USB3 / SATA JMS578 enclosure I talked about above (ConnectLand branded) has a PCB inside which is marked "Atatech HD301 v1.8".
As the onboard led was far too blue shining although tiny 3V3 through 330ohm=1mA, I just cut it a leg with no bad side effect.
