[ECOS] mips64vr4300 gdb-stub problem
Fri Apr 14 02:19:00 GMT 2000
Hi, all. I've successfully built the Gnu tools for mipsvr4300 and the tests( in Nt4.0). And I can download the executable file to the 4373 board with the gdb stub, but I can't get the correct result, it seems that the program keeps running, without stop. The following information is result I get, any help is appreciated, thank you!
bash-2.02$ mips64vr4300-elf-gdb -nw thread_gdb.exe
