Hi all,

I had the same problem under linux (Debian woody):

  msp430-gdbproxy --debug msp430
    debug:     msp430: msp430_open()
    error:     msp430: Could not find device (or device not supported) (4)

And I found the reason in the  HIL.c  file.

In two functions:   ReadTDI   and   ReadTDO
there is written the following line:

  ret = ioctl(fd, PPRSTATUS, &ret);
  ^^^|
      This will overwrite the data from the MSP430... chip.

Without the lefthand operand it works better:

  ioctl(fd, PPRSTATUS, &ret);


Have fun ...
             Andre
