Bochs keeps reseting when calling C++ code.
Posted: Tue Jul 20, 2021 1:10 pm
Hello everybody. I'm following a youtube tutorial on how to make an operating system and I came across an error that I'm not getting over. Basically, I have a bootloader that starts a program outside of the first bootsector (ExtendedProgram.asm). This activates protected mode and then long mode. Then, as shown in the code below, I call a function written in c++. The problem is that when I make the call and start Bochs (if I remove the "call _start" line, the program runs normally), it alternates between a black and blue window and the console is spammed with messages (shown below).
Does anyone know how to fix the problem?
Thanks in advance.
