Debugging code can sometimes take longer than writing it. So how do we use QEMU + GDB to debug RISCV programs? To document this process, we will write the following assembly code using the ADD instruction as an example. We will put 1 into register x2, 2 into register x3, and then add the values … Read more
Last year, I had a colleague who debugged C++ programs very impressively from the command line, which made me quite envious. I planned to write an article introducing how to use gdb for debugging in the command line, but I procrastinated for a long time. This time, I can’t delay any longer. Installing GCC and … Read more
