Re: Pi 4 power LED blinking while switched off

That does surprise me. However your TV's behaviour is also unusual - nothing like your switching HDMI channel happened with my setup. So what make, model etc.? Anything else connected to other HDMI ports? Is it a "SMART TV"? Our SMART TV is sometimes "too smart" and confuses a DTV box connection so...

What type/make/model of USB C PSU are you using? (AIUI this issue shouldn't happen with the official PSU and is quite rare - the reports in this thread are the only ones I have seen since early testing before the official PSU was available).
Trev.
I have only using the official PSU.

Re: Pi 4 power LED blinking while switched off

This a logged, "known issue" and seems to depend on whether HDMI is left connected together with a USB C PSU connected but unpowered at the AC mains. This is a big issue for me, because I would like to use a remote controlled AC socket . But if the PSU is remain connected with one wire (the power s...

Re: Pi 4 power LED blinking while switched off

If you remove the HDMI cable or unplug the TV from mains power does the LED stop lighting? If I unplug the HDMI or the power cable on RPi, the LED stop lighting. The power switch is break one wire while switched off. You could try connecting the Pi to different HDMI ports on the TV. Maybe some prov...

Re: Pi 4 power LED blinking while switched off

I have the same issue, when the RPi4 is switched off by power strip and the HDMI is connected, the power LED is blinks every ~30 seconds. It's very annoying because my TV switching the source input automatically when it detects a device on HDMI port. So I cannot using a power switch, because the TV ...

Unfortunately is only shows 30Hz- on my TV and my monitor (both capable to do 60 Hz).
My UHD Samsung TV is only supports 60Hz (basically HDMI 2.0) if the HDMI UHD color option is enabled on the HDMI port.

Re: rpi-bootloader updates for Aug 19?

I don't see why it couldn't be. I can see no reason there could not be a completely automated Boot Eeprom upgrade process The configuration options are included in the binary . If you are not satisfied with the default settings (old and/or new ones), currently the upgrade process is requiring some ...

Okay, can you please confirm me that neither the sdcard or the ethernet goes through this hub?
Thanks!
This is dedicated to the 4 USB ports only, so you can safely disable it.

Re: Make backups of a live running Raspberry Pi?

I usually using the systemback.sh script on Ubuntu/Debian to create restore points, but it's perfectly fine with Raspbian as well. This is just restore point, so you can restore the running system to the previous state (but you may need to edit cmdline.txt and fstab if you perform a restoration on a...

There are currently no user updatable settings in the EEPROM, but that is probably going to change.
Check the documentation, there are three updatable settings (BOOT_UART, WAKE_ON_GPIO and POWER_OFF_ON_HALT) in the version 2019-07-15.

Re: Latest Pi 3 B+ and only Pi 4 linux kernel missing pm_usage_cnt

If you want an unavailable feature, just configure, compile and install your own kernel. See the kernel source and the official documentation:
