Illegal Instruction

[kenshaw]

Hi, I'm hoping you can help me figure out this issue. I cannot seem to get any of the armv6l images to work, always ending up with some variation on an Illegal Instruction being reported by QEMU. For example (from here):

+ cd /usql
+ sudo apt install -y git upx tar bzip2 golang

Is this an issue with the current Raspberry PI images? Any help would be appreciated, as I'd like to start producing armv6l and arm64 release binaries for `usql.

The workflow I'm trying to use is here: https://github.com/xo/usql/blob/master/.github/workflows/arm.yml

I was able to compile usql for arm64 (aarch64), but cannot figure out what needs to be done to get this runner working. I will try to do it with QEMU locally, but thought I would reach out here to see if there was any insight you might have into this specific issue.

Really appreciate your work on this project, and thanks in advance!

Thank you for your report.
I was able to reproduce the crash. The cause is that you are specifying a cpu_info describing a 32 bits CPU that is not the one that you are using for emulation.

You should determine whether you want to target Pi Zero or not.
If you do (which seems to be implied with armv6l), proper cpu info is cpuinfo/raspberrypi_zero_w
If you don't (other 32 bits CPUs are armv7l), you should use cortex-a7 for option cpu.

I am updating the documentation as part of #83 and will close this issue accordingly.
