| GDB commands by function - simple guide | |
| --------------------------------------- | |
| More important commands have a (*) by them. | |
| Startup | |
| % gdb -help print startup help, show switches | |

| *% gdb object core core debug (must specify core file) | |
| %% gdb object pid attach to running process | |
| % gdb use file command to load object |
You might want to read this to get an introduction to armel vs armhf.
If the below is too much, you can try Ubuntu-ARMv7-Qemu but note it contains non-free blobs.
First, cross-compile user programs with GCC-ARM toolchain. Then install qemu-arm-static so that you can run ARM executables directly on linux
If there's no qemu-arm-static in the package list, install qemu-user-static instead
