Scott Tsai's Embedded Linux Tutorials

1. How to Handle a Linux BSP: from u-boot to "Hello World!"
• Configure a minimal Linux system capable of running a "Hello World" C application from the pack of software that your chip vendor calls their Linux "Board Support Package".
• Go through a "board bring up" process on an emulated ARM hardware platform
• Configure and build the u-boot bootloader, the Linux kernel, the busybox minimal application environment and how to get dynamically linked executables to run.
• Uses the qemu emulator to emulate an ARM hardware platform that loads all software over the network.
2. Embedded Linux Application Debugging: gdbserver, duma, mtrace and oprofile
• Covers remote debugging, buffer overflow and memory leak detectors and the oprofile whole system profiler
• The "mtrace" mechanism covered is only present in glibc/eglibc and not uclibc or bionic though. Developers using Broadcom BSPs and Google Android should look to dmalloc.
3. The Little Languages of Linux
• Covers basic shell scripting
4. The Linux Initial Ram File System
   • Bundle files and applications into the Linux kernel image or do all the setup required until a complicated storage device that contains the "real" root file system can be used.
   • How to build an initramfs image with device nodes without requiring root privileges for "mknod".
5. KGDB Tutorial: using the gdb protocol stub built into the Linux kernel
