Decided to give Channels DVR another try after seeing the RPI info. Purchased the recommended hardwire identified on the website including the WD 4TB USB HDD.
Problem... after using the Raspberry Pi Imager to enable the RPI 4 USB boot and then burning the custom RPI image to the USB hard drive, I cannot get the RPI to boot. The RPI initiates the boot sequence and the HDD is accessed, but after a brief screen flash (see below ) the TV screen goes black and after a second or two the cycle repeats. So I have no clue what will fix the problem.
I did successfully install the Channels Server after booting from a Raspian SD card and subsequently using the terminal to execute the website Linux command:
curl -f -s https://getchannels.com/dvr/setup.sh | sh
So I'm reasonably confident my RPI 4 and network are working okay. Just don't know how to get the RPI 4 to boot from the USB HDD? Unfortunately I don't have a spare USB HDD available or I would have attempted another install using another USB drive.
Here are the only specifics (quick photo of the TV screen during the boot process) I've been able to capture re the failed USB HDD boot:
Appreciate any help. Really was hoping the RPI 'turnkey' was user-friendly and low maintenance. Have an older Dell Optiplex i5 I can resurrect if needed, but the simple RPI is really appealing.
Thanks
