Philips Semiconductors ISP1362 Linux Stack User’s Guide

CROSS_COMPILE = /pub/usr/ bin/arm-linux-

The cross compile path (/usr/include/arm/2.95.3) depends on where the tool chain is installed and the version of the tool chain and from where the tool chain is downloaded.

Similarly edit the Rules.Make of ISP1362 source (/usr/src/AccelentIDPRev4/linux/1362/source) for any changes

•The kernel source directory is different from the one specified above.

•Compile time flags. Refer to section 5.1. If you want any configuration changes. Make sure that PXA250_KIT hardware option is enabled with PXA250_REV4.

•CROSS_COMPILE path

•MS_SIZE_FLAG is set to _8MB_SIZE_ (because of limitation of Accelent board for Mass storage demo)

While configuring the kernel (use menuconfig), enable the following options:

USB core support

USB OTG support

USB Audio Support

USB mass storage support

USB pegasus

USB CATC

USB KAWTH

Save the configuration and exit

#make dep zImage modules modules_install jffs_rootfs jffs_image

As a result, a number of files starting with "nk_" will be created in the root Linux directory:

•nk_jffs_flash.bin: This image includes the kernel and root filesystem

•nk_kernel_flash.bin: This image is just the kernel image, useful if you already have a good root fs image and just need to reflash the new kernel.

•nk_kernel.bin : This is an image that will be loaded into RAM from the card without flashing into ROM. It’s quite useful for debugging or preserving your flash image.

Whichever image you choose to use, copy it to the PCMCIA card and rename it "nk.bin". The card filename must be nk.bin or the bootloader, which is WinCE bootloader, will ignore it.

3.2.2.7.Serial Communication for Debug Output

On the host PC running Linux, minicon can be used to receive debug output (generated by printk) from Accelent IDP. A null-modem cable is required to connect FFUART(J5) port on Accelent IDP board and a COM port host PC. Set Baud rate to 115200, data bits = 8, Parity = none, Stop bits = 1, Flow control = hardware.

3.2.3.Accelent IDP (Rev 04) Target Setup

Follow the instructions given in the Quick Start Guide IDP for Intel PXA250 Applications Processor Linux OS document from the Accelent CD to set up the Accelent IDP.
