Part Number: TMS320F28388D Tool/software: Hi, There is a global structure defined in cpu1 project and our use case is to know the memory address of a member of the structure from cpu2, access those members and read the values stored in them. The structure declaration is given below and the member in question is RawAdcData.w[0] which in turn points to stRawAdcData.RecRPhaseLegBCur : typedef struct { float RecRPhaseLegBCur; float BatLegAVolt; /**snipped**/ } stRawAdcData; #define RAW_ADC_SIZE sizeof( stRawAdcData ) / sizeof( float ) typedef union { stRawAdcData st; float w[ RAW_ADC_SIZE ]; } uRawAdcData; uRawAdcData RawAdcData; As per the linker file, this variable is stored in Global Shared RAM (.bss). I had used below information to obtain from the out file: Get data from .out-file - Code Composer Studio forum - Code Composer Studio ︎ - TI E2E support forums But I could not locate this member variable in the map file. Here's what I did: Obtained from the output of ofd2000: command used: "C:/ti/ccs1270/ccs/tools/compiler/ti-cgt-c2000_22.6.1.LTS/bin/ofd2000.exe" --obj_display=none,sections -v cpu1.out ".bss" Load Address: 0x0000f800 Run Address: 0x0000f800 Size: 0x1a8e Alignment: 2 Loaded Onto Device: Yes Address Unit Size: 16 bits File Offset: 0x1034 # Relocs: 0 Section Type: SHT_NOBITS ELF sh_flags: 0x3 ELF sh_flag: SHF_WRITE ELF sh_flag: SHF_ALLOC TI ext_flags: 0x0 (null) (null) sect_file_ptr = 0x1034 sect_base = 0x0000f800 Looked into the output of nm2000 and could not get the whereabouts of member variable of RawAdcData . Below is what I got: command used: "C:/ti/ccs1270/ccs/tools/compiler/ti-cgt-c2000_22.6.1.LTS/bin/nm2000.exe" -l cpu1.out [5234] |0x00011140|304|GLOB |OBJT |HIDN |8 |RawAdcData There is nothing about " .w[0] " member of union or RecRPhaseLegBCur Please let me know if I missed anything and if you need additional information. Thanks, Rohit
