Device: Powkiddy RGB30
OS: JELOS RK3566-BSP
Build system: JELOS build system with docker
Build options: platform=unix CPU_ARCH=arm64 HAVE_DYNAREC=1 DEBUG=1

Hello. I get a segmentation fault when trying to load games with gpsp through the retroarch interface. However, when I load the core and game directly from command line, it runs fine.

This is gdb output, which I got with some help, I'm not very experienced with gdb so forgive any lack of information:

I could be wrong but it looks like it's crashing when trying to load the BIOS file (gba_bios.bin).

When running through the command line it may be falling back to using the Built-In BIOS instead. Could you try changing your gpsp config in RA to specifically use the Built-In BIOS and see if you still get the same issue? Could be a bad BIOS dump file.

Uhm this crash is very suspicious. Had a similar issue on MIPS back then. This is happening before any emulation happens (during the dynarec init code). It could be a mmap() issue, where memory is mapped in the wrong areas.
The address "0x722061207075206b" seems to be mapped very far away from the main .text section (0x7fedfcca2c).
