Hi, Jifl,

Could you please do me a favor? As you may know, I still have trouble to use
my tool chain with "-O2" option. I believe Nick's point is correct, since
the RAM startup code doesn't initlize the MMU. I have tried to include the
hal_mmu_init in the RAM startup code, the progrem just hang somewhere, it is
not so good to initialize the TLB twice, I guess. I think to rebuild the
gdbstub will be a better solution, I hope I can have a optimized stub code,
could you help me build me and send me a gzipped code privately? Thanks a
lot!
