Hi John,
With try and error i got the elf for the examples.
I tried to run with gdb but i constantly getting this error "Program
recieved signal SIGBUS, bus error". And some times it freezes at the
"Continuing".
I tried to reset the board as it was suggested before running the
example but no use. Any thoughts people ? Does anybody seen similar
error ?
Thanks
Kishore
