•CROSS_COMPILE path
•MS_SIZE_FLAG is set to _8MB_SIZE_ (because of limitation of Accelent board for Mass storage demo)
3.3.2.14.OS Image Creation
To compile the kernel and create the final image to be downloaded into the IDP target, use the command:
#make dep zImage modules modules_install 1362_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.
3.3.2.15.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
3.3.3.Accelent IDP 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.
1.The boot loader boot.bin (from the accelent CD) does not support ISP1362
2.To load the new kernel and root file system from the development environment, copy the
nk_jffs_flash.bin from the earlier section as nk.bin to the CompactFlash card, and boot up the Accelent IDP. Follow the instructions on the Quick Start Guide IDP for Intel PXA250 Applications Processor Linux OS document for detailed loading/booting instructions.
3.Log on to the Accelent IDP as root and execute the following command (This is applicable for the demo environment setup only)
#cd /home/1362/objs #./init_setup
This will make the initial setup for the Accelent IDP for ISP1362 Linux stack. Note that you need to execute this script for the first time only. Connect the Accelent IDP to the Linux host system as a mass storage device, and perform the following on the host system:
4.Initialize and load the ISP1362 stack on to the target system as mentioned in Section 4.2 and connect the Accelent IDP to the host Linux PC as a mass storage device.
