1 Overview

The Software Development Kit or SDK is provided to give the end users an environment where they can develop their own applications and images. This document is intended as a complete, step-by-step guide to create the SDK environment on the 2GB CF and does not contain instruction on how to create an application using SDK. Please note that the SDK is also referred to as development environment in this document.
Please also refer to UM_SDK.pdf (SDK User’s Manual) how to setup/use SDK.

2 Environment

This chapter explains kernels, programs, settings and so on. The contents of this chapter have been applied to SDK.

2.1 Patches to kernel

Before kernel compilation, patches are first applied to the kernel. The following sections lists the patches applied to the kernel.
Note: All patches have already been applied to /usr/src/linux on SDK. The patch files are stored on
/buildtree/src/kernel/patches.

2.1.1 BigPhysArea Patch

XCI-SX1 SDK / SDK Technical Manual
Applying this patch allows the user to allocate a large area of contiguous memory during boot up time which can be allocated or deallocated by the kernel driver that needs it.
BigPhysArea
Patch Application:

2.1.2 Network Driver Patch

The network driver has to be patched to enable a more stable Ethernet device driver for the target hardware (RTL8100C).
Network Driver Upgrade
Patch Application:
cd /usr/src/linux patch –p1 < [source]/bigphysarea.diff
Where: [source] – path where the exploded patch is located
cp 8139too.c /usr/src/linux/drivers/net/
NOTE: This command must overwrite the existing 8139too.c in the MVL3.0 kernel tree.

2.1.3 BootSplash Patch

To display a boot logo and progress bar during boot-up, this patch should be applied to the kernel. Applying this patch enables the user to display the desired effect during boot up.
XCI-SX1 SDK / SDK Technical Manual
Bootsplash Patch
Patch Application:

2.1.4 Keyboard Patch

The keyboard patch applied is to adjust the keyboard repeat interval and delay. The other patch is a Kernel modification to avoid the occurrence of “pc_keyb: controller jammed (0xFF)” error message.
Keyboard Patch
Patch Application:
Keyboard Repeat
“controller jammed”
error
cd /usr/src/linux patch -p1 < [source]/bootsplash-3.0.7-

PS/2 keyboard support CONFIG_PSKEYBOARD PS/2 keyboard support is optional and can be omitted on some systems, for example, some IA32 systems which use IrDA keyboards. If unsure, say Y.
Bus Mouse Support CONFIG_BUSMOUSE Say Y here if your machine has a bus mouse as opposed to a serial
The CONFIG_PSKEYBOARD kernel option should be disabled.

2.1.5 MVL Patches

In addition to applied kernel patches, below is the list of MVL3.0 updates that were applied into our kernel:

2.2 Kernel Configuration and Installation

2.2.1 Kernel Configuration

After applying the required patches to the kernel, it is time to set the kernel configurations. Please make sure that the following configurations are set before building the kernel.
Kernel Configurations
Kernel Features Remarks
ext3 file system
Minix file system Minix’s compact feature makes it ideal for read-
romfs
tmpfs
USB input device support Used for USB I/O Video4Linux Used for the camera module ATA/IDE Used to support IDE CF media Network options’ UNIX domain sockets RAM disk and initrd Used to allow an initrd image load and act as
Loop back device
To enable journaling on an IDE device such as a CF. A journalized file system is required in order to protect the CF’s XIP partition during abrupt hardware on/off events.
only and load-on-boot-time-only partitions Also known as cramfs. It is ideal for storing run­time, read-only data. This dynamic ramdisk fs is used for storing volatile data (such as contents of /tmp and the like)
To allow network communication
the embedded environment’s main file system Used as mount device for cramfs images
UNIX98 PTY, Standard/Generic Serial, and Virtual Terminal supports
Used for serial console terminal requirements
