I want to get name,type,address of global variable from AXF(.AXF is the executable file of keil MDK),I have gotten variable name、address and rough type(eg:object represent variable),The question is how to get specific variable type（eg: int,char..）， My development environment is keil MDK 5.36 (compiler version 5).
C:\Users\10004265\Desktop\RTC_no_debug_str\Project\MDK-ARM\obj>readelf -S YD_DEMO.axfThere are 16 section headers, starting at offset 0x4ebac:Section Headers: [Nr] Name Type Addr Off Size ES Flg Lk Inf Al [ 0] NULL 00000000 000000 000000 00 0 0 0 [ 1] ER_IROM1 PROGBITS 08000000 000034 0013c8 00 AX 0 0 4 [ 2] RW_IRAM1 PROGBITS 20000000 0013fc 00004c 00 WA 0 0 4 [ 3] RW_IRAM1 NOBITS 2000004c 001448 00042c 00 WA 0 0 8 [ 4] .debug_abbrev PROGBITS 00000000 001448 000584 00 0 0 1 [ 5] .debug_frame PROGBITS 00000000 0019cc 000978 00 0 0 1 [ 6] .debug_info PROGBITS 00000000 002344 008890 00 0 0 1 [ 7] .debug_line PROGBITS 00000000 00abd4 0028cc 00 0 0 1 [ 8] .debug_loc PROGBITS 00000000 00d4a0 000c24 00 0 0 1 [ 9] .debug_macinfo PROGBITS 00000000 00e0c4 03695c 00 0 0 1 [10] .debug_pubnames PROGBITS 00000000 044a20 0009aa 00 0 0 1 [11] .symtab SYMTAB 00000000 0453cc 001e00 10 12 285 4 [12] .strtab STRTAB 00000000 0471cc 001bf8 00 0 0 1 [13] .note NOTE 00000000 048dc4 00001c 00 0 0 4 [14] .comment PROGBITS 00000000 048de0 005d10 00 0 0 1 [15] .shstrtab STRTAB 00000000 04eaf0 00009c 00 0 0 1Key to Flags: W (write), A (alloc), X (execute), M (merge), S (strings) I (info), L (link order), G (group), T (TLS), E (exclude), x (unknown) O (extra OS processing required) o (OS specific), p (processor specific)
you may use fromelf.exe combined with the right command line options, instead of readelf:

That is great,the problem is solved .thank you ,Chen Tang.
The problem is almost solved,but the variable type is not perfect to me,I want to get type encode value (a number) instead of a type string.The below is my print using fromelf -a xxx.axf
address size variable name type0x08001ab0 0x10 AHBPrescTable array[16] of const volatile uint8_taddress size variable name type0x20000004 0x4 SystemCoreClock uint32_taddress size variable name type0x08001aac 0x4 ADCPrescTable array[4] of const volatile uint8_taddress size variable name type0x08001ac0 0x10 APBAHBPrescTable array[16] of const volatile uint8_taddress size variable name type0x20000060 0x2 nTime u16
hello，Chen Tang,I consult a question,struct nested struct array ，the software readelf can not parse deeperly，for example，in the lash two line, stCfgInfo.stTxComIdCfg : array[4] of STRUCT_TX_COMID_CFG can not parse deeperly.Thank you !
