Thank you. The assemble's support is just enough for me. How about the gdb's support for eMAC? I have a MCF5249EVB, and I built m68k-bdm-elf-gdb version 6.1.1. The gdb can connect to target. But only regular CPU registers can be accessed. The result of the command 'info regs' lacks all eMAC registers, such as MACSR, ACC0, ACC1, etc. Would anybody tell me how to make the gdb know the eMAC module? thx.
