I assume this has to be a simple problem. I am trying to get
msp430-gdbproxy to work on a gentoo linux system. The base PC works as
I have used the FET tool with the IAR distribution on the machine with
dual boot (Win98).
It looks like msp430gcc is running. But I am stuck on the gdbproxy. I
have parport0 with group users, ppdev loaded as a loadable module.
msp430-gdbproxy is group users also.
When i run it i get:
debug: msp430: msp430_open()
error: msp430: Could not find device (or device not supported) (4)
there is a significant delay between the first and second line (NB if
libHIL.so is not found, ppdev not loaded, or a non-existant port is
requested the error message is immediate)
To get that far it appears you have msp430-gdbproxy talking to the
parallel port OK, but not actually finding the MSP430 device.
Some people find that if their parallel port is not set to SPP (old
original non-DMA parallel port mode) in the BIOS odd things happen. I
haven't found out why. Some people find some modern machines let the
software wiggle the parallel port bits at enormous speed, causing
trouble. This problem may be related to the first one. Some people find
that if the mod TI documented for the early FET tools is not implemented
some things works and some things don't - i.e. performance can be a bit
erratic.
The IAR and mspgcc tools actually use the same JTAG access library, but
the parallel port access code is not common. There may be timing
differences in that which cause different behaviour between the various
software tools on the same machine. Could one of these issues explain
your problem.
These issues really need sorted out..... when I find the time.
I am trying to use a msp430F149.. being an old part.. I expect this is
supported.
It is supported.

Steve
