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: USB problem on Pi 4B

I've got a startech.com S2510BMU33 which uses the ASM1153E chip and it seems to work well on the Pi 4B. ... Time to order more of the startech.com enclosures! I have two types of cable-style adapter, USB3S2SAT3CB with ASM1153E, and USB312SAT3CB with ASM1351 controller chip inside. Both work well in...

Re: Disable Usb Hub on Pi4

Maybe just remove the PCIe interface:

Code: Select all

echo 1 >/sys/bus/pci/devices/0000\:01\:00.0/remove

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:
