Hi,
Since the board doesnot have the nework to test from the net, I tried that to check whether I'm doing the right thing or not.
The board has 512K of flash, onto which I'm writing the U-boot (its of 64K), and in the remaining space, I'm writing the kernel (which is around 350K, and its only for the testing).
Now to boot from the image, I'm planning to do the following,
1> Copy the Image from the flash to the RAM, 2> and then give the control to the image location in RAM (using the bootm command).
the bootm command expects a image file created from a binary with tools/mkimage. e.g.:
mkimage -n 'Kernel Ramdisk Image' -A ppc -O linux -T kernel -C none -e 00400000 -a 00400000 -d zImage.bin zImage.img
If your kernel image in the flash memory was created with the mkimage tool just start it with: => bootm 0xYourflashaddress
or test it with: => imi 0xYourflashaddress
the should produce a output similar to: ## Checking Image at 04000000 ... Image Name: Kernel Ramdisk Image Created: 2004-11-30 9:54:16 UTC Image Type: PowerPC Linux Kernel Image (uncompressed) Data Size: 3010560 Bytes = 2.9 MB Load Address: 00400000 Entry Point: 00400000 Verifying Checksum ... OK
Please confirm me whether I'm doing the right thing.
that should to the trick...
Cheers Simon
