Hi,
I need one clarification regarding load address, entry point inside the Kernel image & the address to where we load the image.
Assume, the image header is as below.
Image Name: Linux-2.6.38-10700-g846a497 Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 2064396 Bytes = 2 MiB Load Address: 80008000 Entry Point: 80008000 Verifying Checksum ... OK
And I load the image using loadb to address 0x80008000.
Will this work?. Because here Image->load_address == Load_address for u-boot. Now u-boot considers this as XIP Image and will not move os data which actually will be at 0x80008040 to 0x80008000
Please correct me if I am wrong
I have attached the console output for reference.
Thanks & regards Gururaja
