In this hands-on workshop, you have a chance to learn some cool tricks working with Linux kernel code. KGDB, the kernel debugger, allows you to debug a kernel running on a different architecture, remotely, just like you would debug a program running in userspace. A powerful trace infrastructure makes it easier to spot issues in time-sensitive systems, when setting a breakpoint is not an option.
1. General information
Day 3: Boards: 30
Day 4: Boards: 10
Cost: free
Registration: just come early, or PM myself (@wooe) on Twitter latest 28.12 23:59:59 if you would like to reserve a seat and board for yourself.
We will provide target boards based on NXP i.MX6ULL Cortex-A9 processors (SoMLabs VisionSOM + VisionCB) to be used during the training, cables, memory cards etc. Participants will be given a voucher code to order the kits at a discounted price.
2. Agenda
- Introduction and VM set-up
- Simple kernel driver that blinks LEDs
- Debugging with KGDB over a serial line
- Tracing
3. Prerequisites
- Linux console basics
- entry-level programming experience
The hands-on does not require you to write your own code, only un/comment.
4. Preparation
Bring your own laptop running Linux or Windows 7, 10. You will need a free USB-A port and an Ethernet port.
In order to get up and running quickly, it is recommended that you install VirtualBox with the Oracle Extension Pack.
For Windows: https://www.virtualbox.org/wiki/Downloads
Linux: use the package manager and documentation for your distro
There will be some time to do this during the hands-on, so don't worry if you come without VirtualBox installed.
5. FAQ
Q: Can I use a Macbook?
A: Sure, but we may not be able to help you get the VM set up if you are not running Linux or Windows. You can always team up with someone using a PC.
A: You forgot about Windows 8
Q: Are you still using Windows 8? ;)
