at this point I managed to build and debug the test program (fet430_1.c) on
my msp430fg439.
I'm using last eclipse, last zylin CDT and embedded CDT, and last mspgcc
build for win32.
the debug process is working, except some things:
1. each step I got 3(three) error message boxes "An error occured, see error
log for details".
the log transcript (verbose gdb output is on) is at the end of message...
2. there is no way to break executing program, gdb is just hang and gdbproxy
is producing continuous output like this:
debug: MSP430_State()
debug: MSP430_State() 1, (-1 steps)
debug: MSP430_State()
debug: MSP430_State() 1, (-1 steps)
debug: MSP430_State()
debug: MSP430_State() 1, (-1 steps)
debug: MSP430_State()
debug: MSP430_State() 1, (-1 steps)
the same situation as I try to step over some long-executing code, like
this:
i = 50000; // Delay
do (i--);
while (i != 0);
here is the log from eclipse:
