Hello, Excellent tutorial! I am getting "Cannot access memory address at 0x80b5e024" error like in the video at 1:37:30. Is there a way resolve it? (gdb) info mem Using memory regions provided by the target. There are no memory regions defined. (gdb)

Update, setting the breakpoint type to hard kinda fixed this issue! telnet 127.0.0.1 4444 > gdb_breakpoint_override hard Is there a way to make it work with soft breakpoints since hard breakpoints are very limited. Thanks

The kernel config CONFIG_STRICT_KERNEL_RWX has to be turned off in order to work with soft breakpoints. This config will make the kernel region read-only and we don't want that!
