Rasp Pi 4 8GB will not boot from Retropie SD card

Honda Z50M

@mitu Just before taking the screen shot (rebooted after update)using the SD card that boots ok.

Then inserted Retropie card and still got same error as per screenshot.

My fully updated system shows different values for the start4.elf file:

size 2227200
hash: b9a4da9e63f3e18fc0256e6fca6232f6

What's the output of dpkg -l | grep raspberrypi-bootloader ?
Is the RetroPie 4.7.1 image booting on the 8Gb system ?

@mitu But surely the start4.elf file and other files stored on the sd card will only be updated on the card that's inserted at the time of update?

At the moment Retropie card will not boot as per screenshot so no.

So could I just copy required files from good card to Retropie card?

What's the output of dpkg -l | grep raspberrypi-bootloader ? Using good card I assume?

Maybe you misunderstood my reply - run the upgrade on the system that works (i.e. the non-8Gb Pi) to ensure you have the latest version of kernel/firmware on the sdcard, before using the sdcard on the new 8Gb system.

@mitu Ok but unfortunately can't do that as I no longer have that Pi (Pi 4 4GB)

I know someone who has one so inquiries made to them for their help.

In this case, you can try using copying the newer start4.elf and fixup4.dat from the working sdcard to your existing RetroPie install and boot from it. If it works, run again an update/upgrade to get the latest firmware and kernel.

@mitu ok I'll try that this evening.

Thanks for your advice thus far

Honda Z50M

@mitu Copied those files over and now boots up BUT Emulation station does not detect anything not even a keyboard so I can' get past that to do the update

mitu

@honda-z50m Use SSH to connect and run the update.

@mitu Over ethernet?

How do I find Pi's IP address?

If you don't have WiFi, yes.

How do I find Pi's IP address?

It's right in the RetroPie's menus, though you can just use the name (retropie or retropie.local) instead.

@mitu ok won't be able to access wifi with PI as I can't type password in etc.

Honda Z50M

@mitu ok I'm in

How do I update?

How do I update?

With the same commands as before - using apt.

Honda Z50M

@mitu ok I'm using winscp and all I have at the moment is the root directory how do I open the pi terminal?

mitu

@honda-z50m Doesn't Commands > Open Terminal get your a command prompt ?

Honda Z50M

@mitu Done that typed both Sudo apt-get and sudo apt update but just get a timeout after 15secs

Looks like WinSCP doesn't like how long it takes for the command to complete. Use Putty instead to login and run the upgrade commands and - after the upgrade is finished - reboot by entering sudo reboot.
