MOunting USB Memory Stick on OSMC Pi

Folks…I’m doing something wrong, I think. I would like to have two USB memory sticks mounted at bootup on my Pi 3B running OSMC (Open Source Media Canter) . If I’m not mistaken the underlying OS is Stretch? The new USB 3 stick is 32 GB formatted vFAT. The old/current is USB 3 16 GB formatted vFat. B...

Re: Unusual Start up Pi B+

Hmmm, tried to repeat the error sequence without success. Darn thing worked the way it is supposed to :-(

I did however, clone the SD card and now have the new one in the Pi. More tests later. Thanks for the ideas....RDK

Unusual Start up Pi B+

I have a Raspberry Pi Model B Plus Rev 1.2 Buster which does not always start up cleanly. If I do a sudo shutdown -h now it shuts down normally but, when I power cycle it to restart, it seems to hang with the power and CPU LED's on solid. If I power off and remove and reinstall the SD card, then it ...

Access SAMBA share behind Firewall

My main network is 10.0.1.0 which is firewalled from my ISP Internet connection by Router/Firewall "A". On that 10.0.1.0 network I have a WiFi router, "B", using the subnet 192.168.1.0.

Re: Serial Port traffic duirng Boot-up

The Nextion support has gotten back to me and have suggested that the 5v power from the Pi is not sufficient/stable enough for the display unit. They suggest powering it from a separate 5v 2.5A wall wart. That is not a problem as I have a tester plug which will separately power the display unit. One...

OS for Pi V3+ via Pi V3?

I have a remote Pi 3 B (Pi 3 Model B Rev 1.2, Buster) monitoring some equipment at a remote location which is not accessible to me right now.

Re: Serial Port traffic duirng Boot-up

Trevor....Thanks for the clarification and the link. Right now the Nextion display is working correctly with "Pi a" after the last cold boot came up normally. Historically it runs for several days before becoming unresponsive (ie it stops listening to the serial traffic). When that happens I will re...

Re: Serial Port traffic duirng Boot-up

Trevor....OK, I'll admit it I'm new to all of this. The USB-to-Serial adapter is plugged into the Pi b and I did not think I should also have it powered from "Pi a" . Should it also be connected to the 3.3V and ground on "Pi a"?

Hippy...I will look into your ideas tomorrow.....RDK

I have putty on another Pi (AKA Pi b ) so I tried the following experiment: 1. I attached the above USB Serial adapter to Pi b and found it in the /dev/tty as ttyUSB0 2. I ran raspi-config on Pi b and enabled both serial options 3. From the " Pi a " which was controlling the Nextion (that display no...

Re: Serial Port traffic duirng Boot-up

Thanks again. Excuse me for being a bit of a novice on this but, that is just what I am!!! I have another Pi on which I can install the SIGROT software. I assume I have to modify the raspi-config setting on that Pi so it can read the serial traffic from the USB-serial device? Life is an experiment a...

Re: Serial Port traffic duirng Boot-up

Thanks for the idea. I have this serial to USB adapter (DSD TECH USB to TTL Serial Adapter with FTDI FT232RL Chip) which I think is what you were suggesting.
