This article mainly introduces how to solve the problem that raspberry pie 4 can not be started. It has a certain reference value. Interested friends can refer to it. I hope you will learn a lot after reading this article. Let the editor take you to know it.

Have you had the problem that raspberry pie 4 can't be started?

1. Description

Compared with the previous raspberry pie, raspberry pie 4 adds the way eeprom starts. So when we insert the mirrored SD card and find that there is no response, at this time, we have to check whether the data of eeprom has been changed.

Disconnect the device, remove the SD card device, and then reconnect. If the green LED indicator does not flash, it indicates that the EEPROM is damaged, or the firmware inside is damaged, and a recovery operation is required.

Or sometimes, setting the TFTP startup setting is wrong, so that you can only boot from the network, and the network is not available. At this point, you also need to restore eeprom.

two。 Detailed operation steps

In previous SD cards, you can often see a file called bootcode.bin. In raspberry pie 4, this file is moved to EEPROM, and if it is in the SD card, this file is ignored on raspberry pie 4.

If the green light flashes continuously, it means that the boot loader bootcode.bin is running normally. But the start*.elf file was not found.

If the bootstrap cannot be executed, you need to consider restoring the bootcode.bin firmware in eeprom.

Step one:

Download Raspberry Pi Imager

Https://www.raspberrypi.org/downloads/

Choose for different platforms.

Step 2:

Select Mirror Operation

Select EEPROM

Just burn it to the SD card.

Step 3:

Insert the SD card and power on. See the raspberry pie led flashing constantly, indicating that the recovery is complete.

If you have a raspberry pie serial port connected at this time, you can see the following output

At this point, the EEPROM has been restored and the normal image burned on the SD card can be started normally.
