The following command uses output redirection to generate a file
pic32-objdump -dS --stop-address=0x9d000500 calc.elf > calc1.da.txt
It produces the following information (abridged)
9d000018 <main>: */ #include <p32xxxx.h> int main() { 9d000018: 27bdffe8 addiu sp,sp,-24 9d00001c: afbe0010 sw s8,16(sp) 9d000020: 03a0f021 move s8,sp int na, nb, nc; na = 14; 9d000024: 2402000e li v0,14 9d000028: afc20000 sw v0,0(s8) nb = na + 21; 9d00002c: 8fc20000 lw v0,0(s8) 9d000030: 24420015 addiu v0,v0,21 9d000034: afc20004 sw v0,4(s8) nc = na & 0x3c; 9d000038: 8fc20000 lw v0,0(s8) 9d00003c: 3042003c andi v0,v0,0x3c 9d000040: afc20008 sw v0,8(s8) return 0; 9d000044: 00001021 move v0,zero } 9d000048: 03c0e821 move sp,s8 9d00004c: 8fbe0010 lw s8,16(sp) 9d000050: 27bd0018 addiu sp,sp,24 9d000054: 03e00008 jr ra 9d000058: 00000000 nop
This command example shows the program header of an ELF file:
pic32-readelf -h calc.elf
with the following result:
ELF Header: Magic: 7f 45 4c 46 01 01 01 00 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement, little endian Version: 1 (current) OS/ABI: UNIX - System V ABI Version: 0 Type: EXEC (Executable file) Machine: MIPS Version: 0x1 Entry point address: 0xbfc00000 Start of program headers: 52 (bytes into file) Start of section headers: 734844 (bytes into file) Flags: 0x70ff1001, noreorder, pic32mx, o32, mips32r2 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: 98 Section header string table index: 95
