Looks like PHP fpm 8.4 is not compatible with 32bit

Unfortunately your device does not support 64bit OS. Some people say you can run it with php8.2, so you would need to downgrade and test that.

Joulinar · 16 October 2025 15:45

I’ve informed our developer @MichaIng

MichaIng · 16 October 2025 16:33

32-bit is not the issue, but ARMv6. See here:

Great, in the last thread folks found a solution (altering build config) that totally makes sense. The Debian sources enforce VFPv3 floating-point instructions, which are not supported by ARMv6, but VFPv2 needs to be used. I added the info to the Raspbian bug report. I really hope Raspbian maintainers find some time to implement it quickly.

Joulinar · 16 October 2025 16:45

Should we block the update on armv6?

MichaIng · 16 October 2025 16:54

I was thinking this would be solved soon after RPi OS Trixie release, but people seem to be not aware (anymore) that 32-bit RPi OS is still Raspbian, i.e. where such issue needs to be reported, or where existing issues need to be pushed to get more traction.

Hence yeah makes sense. I just added the warning for PHP on ARMv6. Good that we still link the dev version of the script everywhere.

Issue solved, new ARMv6 compatible packages have been merged to Raspbian.
