Installation of Xpad driver failed.

System: rpi4 (aarch64)

Seems the kernel is 64bit, while the the rest of the system is 32 bit. Add arm_64bit=0 to config.txt and reboot, then try again to install the driver.

EDIT: did you add yourelf arm_64bit=1 to config.txt by any chance ?

@mitu Thanks you, now the installation was succesful with arm_64bit=0. I didn't add anything to the config.txt file.
It looks that something changed from the Raspberry OS.: https://forums.raspberrypi.com/viewtopic.php?t=349291

Edit: i try with arm_64bit=1 and it's failing too.

Yes, that happened some time ago on the Raspi OS bullseye release when the kernel was upgraded to 6.1, but RetroPie uses the old (buster) release, which still uses the old LTS kernel (5.10.x).
Seems like this change was added also to the legacy Raspi OS, which is unfortunate and a poor move for a system which should get only security updates.

EDIT: I've asked in the RPI forums if the change was an error or the bootloader upgrade was intended. We'll see how we tackle this depending on the response.

@mitu I am not sure if this helps very much and yeah I am new but. Same issue and I think the issue is more that the recent update is failing to install the headers. When I look at the file system both folder /lib/modules/5.10.103-v8+/build or /lib/modules/5.10.103-v8+/source are not there. Attempting to reinstall the raspberrypi-kernel-headers package errors out (after a long time but it eventually gives up). Example error that happen are "Error! Bad return status for module build on kernel: 5.10.103-v8+ (aarch64)" and says to consult the make.log. Does this for both xpad and xpadneo. Other errors are the exact same however referencing different kernel numbers. When looking at the log for xpad that specially is for this kernel:

The end result seems to be that after this retroarch no longer recognizes the old controller combos to both exit or go to retroarch menu (my controller still works thankfully). Workaround for that for me has been to manually set hotkey button combos inside of retroarch and save the config

...

The headers are installed, but they're not properly configured for the 64bit kernel:

pi@retropie:~ $ dpkg -l | grep kernel-headers
ii  raspberrypi-kernel-headers           1:1.20230425~buster-1                    armhf        Header files for the Raspberry Pi Linux kernel

pi@retropie:~ $ ls -ld /lib/modules/5.10.103-v8+/build
ls: cannot access '/lib/modules/5.10.103-v8+/build': No such file or directory

pi@retropie:~ $ ls -ld /lib/modules/5.10.103-v7l+/build
lrwxrwxrwx 1 root root 36 Mar  8  2022 /lib/modules/5.10.103-v7l+/build -> /usr/src/linux-headers-5.10.103-v7l+

Just apply the workaround I posted above and reboot, then the drivers can be installed without the build errors.

It looks that is affect and the building of lr-swanstation from Retropie-Extra repo. So, if someone want to install this emulator add the arm_64bit=0 to config.txt file, reboot and then try again.

@mitu Forgive me if this seems obvious but I do not see where the config.txt file is stored in this thread. Where is it?

@stabicron It's on the boot partition of the sdcard and you also can find it at /boot/config.txt from your running system. You can run

sudo nano /boot/config.txt

to edit the file after you exit EmulationStation.

It's going to affect more than one package, there are quite a few emulators that use uname -m to determine if the system is 32 or 64bit and set the build parameters accordingly. There's no point in keeping track of them, since running a mixed 64/32bit kernel/userspace is not a very common configuration.

@mitu Thank you. Just tried it and worked for xpad and a couple of the others that were running into the same thing

@mitu Thanks for your help. Read it yesterday, tried it and it helped my build too. Best Regards

It looks that the change that was added to Raspi Buster Lite, was a mistake. Soon an update will fix this.

The updated packages (kernel/firmware-bootloader) for have been released for Buster, the modifications suggested earlier to config.txt should not be needed anymore.

@windg Nice.
