We will get a custom Au1200 based board soon thus I want to speed up on using BDI2000, gdb and Yamon. I halt the Db1200 at somewhere in the reset code using BDI telnet interface. Then connect to the target. But I cant single step reset code because gdb complains warning: GDB can't find the start of the function at 0xbfc005a0 GDB is unable to find the start of the function at 0xbfc005a0 and thus can't determine the size of that function's stack frame. ... This continues until a C-like environment is setup, c_entry(). What I want to learn is is there a way to single step the reset code? Or I am on my own and be careful when writing/chaning code during this phase? What's your usage patterns here guys? Thanks... -- Bora SAHIN
