Can someone confirm that the load address for the u-boot is correct - i currently have: UBOOT_KERN_LOADADDR = 0x80001000 UBOOT_KERN_STARTADDR = 0x80001100 The UBOOT_KERN_STARTADDR was obtained from: [mike@f64-current /usr/home/mike/omega2/tftpboot]$ readelf -h kernel.MT7628_FDT ELF Header: Magic: 7f 45 4c 46 01 01 01 09 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement, little endian Version: 1 (current) OS/ABI: FreeBSD ABI Version: 0 Type: EXEC (Executable file) Machine: MIPS R3000 Big-Endian only Version: 0x1 Entry point address: 0x80001100 Start of program headers: 52 (bytes into file) Start of section headers: 5653480 (bytes into file) Flags: 0x50001001, mips32, o32, noreorder Size of this header: 52 (bytes) Size of program headers: 32 (bytes) Number of program headers: 6 Size of section headers: 40 (bytes) Number of section headers: 32 Section header string table index: 29 However the UBOOT_KERN_LOADADDR was from what was suggested earlier and not sure how to work out (by getting to as far as I have on the omega i have just assumed it is and all is ok with it but is one variable i am not sure is correct). The only place i can find values for .text is from readelf but do not know if these values are relevant and what to do with them to confirm if 0x80001000 is correct eg: [mike@f64-current /usr/home/mike/omega2/tftpboot]$ readelf -S kernel.MT7628_FDT|more There are 32 section headers, starting at offset 0x5643e8: Section Headers: [Nr] Name Type Addr Off Size ES Flg Lk Inf Al [ 0] NULL 00000000 000000 000000 00 0 0 0 [ 1] .text PROGBITS 80001100 001100 3520b0 00 AX 0 0 16 [ 2] .MIPS.stubs PROGBITS 803531b0 3531b0 000010 00 AX 0 0 4 [ 3] .rodata PROGBITS 803531c0 3531c0 06d354 00 A 0 0 16 [ 4] set_sysctl_set PROGBITS 803c0514 3c0514 0012b4 00 A 0 0 4 [ 5] set_sysuninit_set PROGBITS 803c17c8 3c17c8 0004e4 00 A 0 0 4 [ 6] set_sysinit_set PROGBITS 803c1cac 3c1cac 0009ac 00 A 0 0 4 [ 7] set_cam_xpt_xport PROGBITS 803c2658 3c2658 000028 00 A 0 0 4 [ 8] set_modmetadata_s PROGBITS 803c2680 3c2680 000518 00 A 0 0 4 [ 9] set_cam_xpt_proto PROGBITS 803c2b98 3c2b98 000010 00 A 0 0 4 [10] set_kdb_dbbe_set PROGBITS 803c2ba8 3c2ba8 000008 00 A 0 0 4 [11] set_ofw_set PROGBITS 803c2bb0 3c2bb0 000004 00 A 0 0 4 [12] set_uart_fdt_clas PROGBITS 803c2bb4 3c2bb4 000004 00 A 0 0 4 [13] set_cons_set PROGBITS 803c2bb8 3c2bb8 000008 00 A 0 0 4 [14] usb_host_id PROGBITS 803c2bc0 3c2bc0 000020 00 A 0 0 32 [15] .interp PROGBITS 803c2be0 3c2be0 00000d 00 A 0 0 1 [16] .hash HASH 803c2bf0 3c2bf0 00b2c8 04 A 17 0 4 [17] .dynsym DYNSYM 803cdeb8 3cdeb8 01cad0 10 A 18 1 4 [18] .dynstr STRTAB 803ea988 3ea988 01cae6 00 A 0 0 1 [19] .reginfo MIPS_REGINFO 80407470 407470 000018 18 A 0 0 4 [20] .data PROGBITS 8040a000 40a000 03d200 00 WA 0 0 8192 [21] .rld_map PROGBITS 80447200 447200 000004 00 WA 0 0 4 [22] set_pcpu PROGBITS 80447240 447240 000d04 00 WA 0 0 64 [23] .got PROGBITS 80447f50 447f50 0019cc 04 WA 0 0 16 [24] .dynamic DYNAMIC 8044991c 44991c 0000c8 08 A 18 0 4 [25] .bss NOBITS 80449a00 4499e4 08a110 00 WA 0 0 64 [26] .comment PROGBITS 00000000 4499e4 010753 00 0 0 1 [27] .pdr PROGBITS 00000000 45a138 04f840 00 0 0 4 [28] .gnu_debuglink PROGBITS 00000000 4a9978 000014 00 0 0 1 [29] .shstrtab STRTAB 00000000 4a998c 00016d 00 0 0 1 [30] .symtab SYMTAB 00000000 4a9afc 04eb40 10 31 12809 4 [31] .strtab STRTAB 00000000 4f863c 06bdac 00 0 0 1 Key to Flags: W (write), A (alloc), X (execute), M (merge), S (strings) I (info), L (link order), G (group), x (unknown) O (extra OS processing required) o (OS specific), p (processor specific) [mike@f64-current /usr/home/mike/omega2/tftpboot]$ On 09/05/2017 15:07, Mori Hiroki wrote: > Hi.
