Most likely u-boot is running at 0x23f0.0000. Usually the initial bytes are used for special purposes (I don't remember the details but irq vectors might be located there), so anything in-between should work. Try 0x2010.0000 (1M within the RAM area) or whatever. In short: yes, it depends on the detailed memory map. A good choice, if you don't want to know the details, is the address where you load the kernel image (it's on the manual, or default boot command). Note: not the flash address, but the load address in the range 2000.0000-2400.0000; it usually is 32k in the ram, but whatever it is, that is a safe address. 0 and 0xc000.0000 are definitely not good. > If I find the right address and use it on the -Ttext link time and > on the tftp load and go command, my original program should work? Yes.
