Your code works pretty fine on my board. I remember I have something might
be different in my configuration. I usually can not straight forward use the
code generated by "ecosconfig new vrc4373", I usually modify two things, one
is to delete the "-O2" option for compiler, another is to set both the
serial port drive baud rate to 38400b/s. If I don't delete the -O2 option,
the gdb usually hang there after I type "cont" after successfully download
the code. This problem has been reported by Charles on this list, his work
around solution is not to optimize the code, I follow the suggestion and it
works. I tried several NEC board, the result is the same, I must delete
the -O2 option every time. Jifl, do you apply this usually? or everything
just works fine for your board? I think this option might bring some
differences for our pci1.exe code. But anyway, yours code just works fine on
my board, probably my toolchain is not as good as yours. :) I use
binutils2.10 and egcs20000313 snapshot, insight 5.0. (I follow Charles
suggestion on this list actually.), I am not sure if his pci test program
works fine or not.

Any good suggestion? Please kindly let me know. I will be grateful!
