Using XELK[edit | edit source]
Q: I've received the XELK package. How am I supposed to start working with it?[edit | edit source]
A: You can follow the steps listed below:
- Check the kit contents with the packing list included in the box
- Insert the SD into the card slot on the carrier board
- Connect the power supply adapter and the serial cable
- Start your terminal emulator program
- Switch on the power supply
- Monitor the boot process on the serial console
- Install and configure the development environment as described in the XELK Quick Start Guide.
Q: How can I update the XELK version?[edit | edit source]
A: All XELK source trees (U-Boot and Linux kernel) are provided as git repositories. This means that these components can be kept in sync and up to date with DAVE Embedded Systems repositories. Once the a git account is enabled, the developer can clone the repository and synchronize a source tree using git commands. For further details, please refer to XELK Updates.
Q: Where can I found the XELK Quick Start Guide document?[edit | edit source]
A: this document is included in the XELK distribution and can be downloaded from XELK_Quick_Start_Guide
Q: How can I configure the Axel system to boot from network?[edit | edit source]
A: Booting from network is very helpful during the software development (both for kernel and applications). The kernel image is downloaded via TFTP while the root file system is remotely mounted via NFS from the host. It is assumed that the development host:
- is connected with the target host board through an Ethernet LAN
- exports the directory containing the root file system for the target through the NFS server
- runs a TFTP server.
- has a proper subnet IP address
For detailed information, please refer to Configuration net_nfs
