Hello, I have the following question. It is about the adresses where the U-boot and Linux Kernel are copyed in the SDRAM from NAND.In my board config file I have:#define CONFIG_SYS_LOAD_ADDR 0x22000000 /* load address */Is that the load address of the U-boot?
No, it's the default address to load the kernel (or other image). Note that this is where the uImage goes, not where the kernel gets uncompressed to (which is specified in the uImage header).
U-Boot is loaded near the top of SDRAM (or the portion of SDRAM that U-Boot has mapped).
BTW, you should use a subject line that is more specific to your question, such as "What is CONFIG_SYS_LOAD_ADDR?" or "Where does the kernel get loaded with <command name>?". "One basic U-Boot question" doesn't give any clues to people skimming the list to see if it's the sort of question they might have the answer to.
Also where is defined the load address of the Kernel because may be I need to leave more free space about the Kernel and RootFS?
CONFIG_SYS_LOAD_ADDR is the default, but you can and should override it in the arguments to the command doing the loading.
