I'm trying to learn, but couldn't pass the following stage: I have a s3c245 based board, I have a working compressed kernel image zImage, this image boots properly via u-boot-1.1.6, however I simply failed to load (i.e., boot vmlinux) via u-boot directly from SDRAM. more details: 1. I let the target boot until the message of " Hit any key to stop autoboot: " for which I hit enter, (this initialized the board enables MMU, I-Cache, .. etc); 2. board info as seen by u-boot # bdinfo arch_number = 0x00000648 env_t = 0x00000000 boot_params = 0x30000100 DRAM bank = 0x00000000 -> start = 0x30000000 -> size = 0x04000000 DRAM bank = 0x00000001 -> start = 0x38000000 -> size = 0x04000000 ethaddr = ...:5B ip_addr = ...200 baudrate = 115200 bps 3. laod vmlinux to SDRAM : tftp 30008000 vmlinux TFTP from server ...210; our IP address is ...200 Filename 'vmlinux'. Load address: 0x30008000 Loading: T ############ ..... 4. # bootm 30008000 ## Booting image at 30008000 ... Boot with Image do not support this address : 30008000 Starting kernel ... and nothing happens it probably crashed somewhere, why zImage works while vmlinux does not? thanks, ferar
