Good question, I don't see any reason why someone could not simply follow that example. bdinfo also prints the relocaddr on ARM: DA850-evm > bdinfo arch_number = 0x0000086D boot_params = 0xC0000100 DRAM bank = 0x00000000 -> start = 0xC0000000 -> size = 0x08000000 ethaddr = 00:08:EE:03:D6:D2 ip_addr = 192.168.1.3 baudrate = 115200 bps TLB addr = 0xC7FF0000 ==> relocaddr = 0xC7F53000 reloc off = 0x06ED3000 irq_sp = 0xC7E22F70 sp start = 0xC7E22F68 FB base = 0x00000000 I'm not proposing that others do not get the relocaddr by other means. My intention was only to share the current recipe I am using to debug after relocation.
