I may have described some problems in my previous question. To eliminate that problem I had to flash my sd-card with the latest buster release. After that I am frequently facing these problems, 1. While using Facebook with Chromium I am getting a lots of processor throttling(Red bars with less power symbol) 2. I found that chromeium is making a lots of processes into the task manager 3. I am getting low power signal frequently after this update.Also the temperature is spiking too. How am I supposed to fix this problem!!

  • Which Pi are you using? What power supply?

  • Raspberry Pi 4B, 5V-2.4A Oct 20, 2019 at 16:37
  • Buy the official 5.1V 3A psu raspberrypi.org/products/type-c-power-supply What temperature is your CPU ? How much memory has your Pi4 got?

  • I found that chromeium is making a lots of processes into the task manager - yeah, Chrome/Chromium tends to be s resource hog Oct 21, 2019 at 8:26

I am getting low power signal frequently after this update.

An update cannot cause this. What can is overclocking, or a weak power supply.

"What power supply?" 5V-2.4A

Get the official power supply.

Raspberry Pi 4B

They recently released an EEPROM update for the Pi 4 which reduces power consumption by up to 0.3 amps.
Just run these commands in the terminal to install it:

wget --no-check-certificate 'https://docs.google.com/uc?export=download&id=1PXwrnhAXKB1hb5J6_EfPy5zLQkqnbGba' -O vl805_update_0137a8.zip
unzip vl805_update_0137a8.zip
chmod a+x vl805
sudo ./vl805 -w vl805_fw_0137ab.bin
sudo reboot now
  • can it be done with apt ? Oct 23, 2019 at 22:21
  • No. apt deals with packages in linux. The EEPROM is low-level bootcode for only the Pi 4, similar to BIOS on a Windows computer.

  • I found the pakage from apt today. A big save. it was an eeprom-image Oct 24, 2019 at 6:01
  • Sorry I misunderstood. I thought you were asking if an apt update would update the EEPROM, and no it won't. But yes, you can use apt to install an EEPROM-updating tool. For pothers who see this, the tool is called rpi-eeprom, and the images are in a separate package called rpi-eeprom-packages.
