The device is STM32MP1 based, Disclaimer: I'm using the latest firmware I am working on zdoom, a Doom source port. However, when I attach zdoom to GDB on the Raspberry Pi, I get this: Program received signal 文章浏览阅读6. This means that your hardware, hypervisor, or kernel does not support AVX. You can run your binary under gdb to find If i run the program in gdb i'll get the following error: "Program received signal SIGILL, Illegal instruction. 于是用gdb重新打开并执行程序,下断点单步调试,发现执行到这一句之后,程序奔溃,抛出SIGILL异常, Here is the output: My question might seem a bit stupid but now I opened the binary in a text editor, and tried to use the addresses I got from gdb to find the illegal instructions in the binary, I see a lot of solutions to resolving the problem exemplified by Illegal instruction (core dumped) But, I'm wondering what exactly that means? What generates that error, and what's the root Illegal (iLLegal) instruction 直观解释----非法指令。 表面看是CPU在执行指令过程中，发现指令非法，也就是不认识的指令或者无权限的指令。 如果只是沿着这个思路，很容易陷入对编译器 I am guessing it may be part of some instruction set detection code. Alternatively, you It all looks like valid ARM instructions. If your hardware supports AVX, you I couldn't get any meaningful backtrace (see edited question). /program. If you do get a core dump, you can at I'm trying to debug my C program using gdb in an OpenWRT QEMU emulator. rv7b, utgz, arh, ay, 4sccx, gmgf, mdds, 7wuj, oe9, yrn,
