segfault about ticker

[thaihugo]

This probably a bug with 16K pages. If you use the kernel=kernel8.img in the /boot/firmware/config.txt (the one that is actually used on the RPI4) it willl work because this is a 4K page kernel. I've tested this solution myself.

To the developer: This bug is related to the ability in newer kernels to work with 16K memory pages. It means that something in your components is probably not happy with this king of configuration. I hope it can shed some light on what's happening.

I don't have access to a system to replicate confirm the fix / replicate this issue but I believe it is related to upx and this issue. I've upgraded the version of upx before building the latest release v4.6.3 which should fix the issue. When you have a moment, give the latest version a shot and let me know if it fixes the problem.

The new v4.6.3 indeed solves the problem. The build runs perfectly on a 16K page kernel. Thanks for solving this so fast!

FYI. I am running the same version of ticker on the same O/S on a rPi 4 and it works well

Thanks for reporting the issue and the suggestion on the root cause. I'll take a look into fixing it in the next week or two

Thank you for taking the time to respond to this problem.Been using ticker for years on rPi. It's regrettable it no longer runs. Do you know if i change the kernel page size in config.txt will result in any performance issues on the rPi5 ?

Officially, it would be around 10% performance lost approximately. But from my experience, you can't really fell the difference if you are not maxing a CPU with an heavyweight app or an emulation. For desktop work, you will probably forget the speed from 16k pages kernel after a few minutes. Le 2 juin 2024 11:47:21 UTC, herby-popnecker ***@***.***> a écrit :
