LH7A40x Linux Board Support Package (BSP)

NXP provides a Linux Board Support Package (BSP) that supports most of the peripherals of the LH7A40x microcontrollers as well as several target boards. This board support package is maintained by NXP Semiconductors and is periodically updated with issue fixes or new features.

The Linux LH7A40x BSP has the following kernel features:

• Support for Linux kernel 2.6.29.6
• Support for the Logic PD LPD7A400 and LPD7A404 boards
• Compact Flash support
• AC97 audio (playback) support
• 10/100 ethernet/PHY support
• Support for 3 UARTs
• Support for the LCD controller
• USB host support
• Touchscreen support

The Linux LH7A40x BSP has the following bootloader features:

• Support for Apex-1.6.8
• Ethernet boot support
• NOR support

The Linux kernel patches are available as separate downloads for users who wish to develop their own Linux system. A complete Linux system can also be built with the Linux Target Image Builder (LTIB), which will handle most of the tasks of gathering packages and patches, configuring images, building the root files, and deploying the image to the target board.

• LH7A40x Linux BSP User's Manual, V1.00 (Oct 23, 2009)
• LH7A40x Linux Kernel (2.6.28.96) Patches (Oct 23, 2009)

The easiest way to get started with Linux and the LH7A40x microcontrollers is to download the LH7A40x Linux User's Manual (above) and follow the steps to build and deploy a complete Linux system on the LPD7A40x board. The User's Manual will provide the quickest and easiest method to get the necessary tools and software and build the necessary images and root filesystem.

Users who have had prior experience building and deploying a complete Linux system can download the Linux kernel patches (above) and the Apex bootloader (below).
