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.
