器件型号：AM625SIP工具/软件：
您好、
操作系统映像加载到 0x80000000、始终在 SDK 版本为 9.2 及更高版本时工作。
但 除非将加载地址重定位到 0x81000000、否则 SDK10.1 uboot 无法启动操作系统。
我在 SDK 10.1 中怀疑有器件保留了 0x80000000、接近该值。
我在 bdinfo 的输出中检查了保留的条目,但看不到它。
=> bdinfo boot_params = 0x0000000000000000 DRAM bank = 0x0000000000000000 -> start = 0x0000000080000000 -> size = 0x0000000020000000 flashstart = 0x0000000000000000 flashsize = 0x0000000000000000 flashoffset = 0x0000000000000000 baudrate = 115200 bps relocaddr = 0x000000009bf03000 reloc off = 0x000000001b703000 Build = 64-bit current eth = ethernet@8000000port@1 ethaddr = 08:04:b4:31:12:12 IP addr = <NULL> fdt_blob = 0x0000000099ed1300 new_fdt = 0x0000000099ed1300 fdt_size = 0x0000000000012a80 multi_dtb_fit= 0x0000000000000000 This will not be a case any time lmb_dump_all: memory.cnt = 0x1 / max = 0x10 memory[0] [0x80000000-0x9fffffff], 0x20000000 bytes flags: 0 reserved.cnt = 0x4 / max = 0x10 reserved[0] [0x98ecb000-0x9fffffff], 0x07135000 bytes flags: 0 reserved[1] [0x9c700000-0x9d9fffff], 0x01300000 bytes flags: 0 reserved[2] [0x9db00000-0x9e6fffff], 0x00c00000 bytes flags: 0 reserved[3] [0x9e780000-0x9fffffff], 0x01880000 bytes flags: 0 devicetree = separate serial addr = 0x0000000002800000 width = 0x0000000000000000 shift = 0x0000000000000002 offset = 0x0000000000000000 clock = 0x0000000002dc6c00 arch_number = 0x0000000000000000 TLB addr = 0x000000009bff0000 irq_sp = 0x0000000099ecfff0 sp start = 0x0000000099ecfff0 Early malloc usage: 3bc0 / 8000
请帮助澄清这一点。
谢谢！
