MetaWare debugger (MDB) is still used as a primary tool for interaction with target via JTAG. Moreover some very advanced features are not yet implemented in GDB for ARC (and not sure if they will be implemnted sometime soon given complexity and rare need for those features for common user). So if we're talking about development process when U-Boot is loaded in target memory not by low-level boot-loader but manually through JTAG chances are high developer uses MDB for it. But MDB doesn't support PIE (position-independent executable) - it will refuse to even start - that means no chance to load elf contents on target. Then the only way to load U-Boot in MDB is to fake it by: 1. Reset PIE flag in ELF header This is simpe - on attempt to open elf MDB checks header and if it doesn't match its expectation refuces to use provided elf. 2. Strip all debug information from elf If (1) is done then MDB will open elf but on parsing of elf's debug info it will refuse to...
