Hello
I'm having some trouble whit Micro-Blox LPC 2478. I'm loading uLinux.bin to the flash address 80000000 and cramfs.img to the addres 80200000. This is oke but when it extracts to the ram i suppose then its starts at address a1500000 for the linux and at address a1800000 for the romfs.img but the romfs image is more than 2 mbyte because the ram is only 32 mbyte so it doesn't fit in the ram. How can i change where to extract the linux kernel and the file system, and mount to linux ? Thanx.
