Use BDI2000 to debug Linux kernel and modules Hansel@163.com2007-12-22 BDI2000 is a JTAG debugger with high cost performance. It supports multiple embedded processors such as ARM, MIPS, and XSCALE by loading different firmware. What I use isThe mips version of bdiGDB, that is, it can be simulated as a gdbserver and used with gdb for source code-level debugging. T

Linux kernel interacts with users. Linux can output information through the serial port during the startup process, so that you can clearly understand the Linux Startup Process. Although it is not a task that must be completed by bootloader, output via serial port is a powerful tool for

integrated more quickly and more patches can be added to the kernel. As the Linux kernel developer community expands, it is very important to modify the Controller to help keep track of all changes. Since everyone can integrate these changes into the main Linux kernel, BitK
