[U-Boot] uboot newbie question on booting ep405 board
by David Li 19 Apr '13

19 Apr '13

Hi, I am new to using uBoot and learning with a EP405 board. The board is up with the original uBoot that comes with it. But I have encountered some problems booting up Linux. I wonder if anyone can give me some hint or help what went wrong. Basically I built the Linux uImage and device tree blob for EP 405. Both were downloaded on to RAM - uImage at memory 0x200000 and ep405.dtb at 0x4000000. When I used "bootm" to boot the kernel, I always get "Bad Magic Number" like this: => bootm 0x2000000 - 0x4000000 ## Booting image at 02000000 ... Image Name: Linux-3.7.8 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2571848 Bytes = 2.5 MB Load Address: 00000000 Entry Point: 00000000 Verifying Checksum ... OK Uncompressing Kernel Image ... OK ## Loading RAMDisk Image at 00000000 ... Bad Magic Number U-Boot 1.2.0-gd35b508a-dirty (Sep 19 2007 - 14:13:23) What's wrong? Why it's loading ramdisk at 0000000? I built the kernel and initramfs together in the uImage.

When we need the copied code/data in the main memory, we can flush the cache now. It uses the existing function flush_cache. Syntax is flush_cache <addr> <size> The addr and size are given in hexadecimal. Like memory command, there is no sanity check for the parameters.
