Hi Kim, Dave, The current recommended practice on the denx.de wiki is to have a 12K FDT blob (0x3000). My latest personal convention for memory locations is to put the FDT blob at a semi-arbitrary base address and set the loadaddr 32K higher (could use 64K if we want to be paranoid about blob growth). The advantage is that the kernel can grow or shrink (ha!) fairly often, but the blob should remain fairly small and fairly constant. This is better than dropping pieces all over memory. This is what I've been running lately: setenv fdtaddr 400000 setenv loadaddr 408000 setenv ramdiskaddr 1000000 Best regards, gvb ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
