The gdb debugger can connect to the target with command 'target bdm /dev/bdmcf0'. my problem is the debugger can display only basic CPU registers, the eMAC registers such as MACSR, ACC0, ACC1 can't be accessed. The 'info reg' command also results the basic registers. How can I tell the gdb to read and modify eMAC registers? thx Chao Xiang
